  • Green Transportation for a Greener and Cleaner Planet

    Green Transportation for a Greener and Cleaner Planet

    Green transportation refers to sustainable methods of travel that don’t create greenhouse gases or contribute to air pollution. Walking and cycling to work or using commuter rail are great ways of going green while saving money and getting exercise!

    Transportation accounts for 29% of greenhouse gas emissions in the US. To lower that figure, consider taking public transit, driving less frequently or carpooling with coworkers.

    Alternative Fuel Buses

    Utilizing alternative fuel buses is one way to lower carbon emissions and air pollution in urban settings. Bus fleets now come in various alternative energy forms, including bio-diesel, compressed natural gas (CNG), propane and electric. Beyond their environmental advantages of reduced CO2 levels, these buses also represent more cost-effective operational and maintenance expenses savings for transit agencies.

    Public transit systems across the nation have already implemented hybrid-electric buses and more are considering this transition. According to APTA, 16.7% of buses in the U.S. currently utilize alternative fuel sources – CNG/LPG dominate this category with 74% use; biodiesel makes up 7.4%, hydrogen/propane make up smaller portions while hydrogen can also be found as an option.

    Hybrid electric buses reduce carbon dioxide emissions by 24% when compared to diesel-powered buses while simultaneously reducing nitrous oxides by 50% and particulates by 90%. Although hybrids initially cost more than diesel-powered buses, Lee County Transit quickly recovers the additional expense through reduced fuel usage costs as well as lower brake maintenance expenses.

    UCLA is also conducting trials with electric buses that can travel up to twice as far. Not only will these help UCLA meet its goal of zero net greenhouse gas emissions by 2025, but will also support sustainability research initiatives at the school.

    This study’s objective is to create an analytical framework capable of automatically creating a comprehensive conversion plan tailored specifically for each transit agency, taking into account their fleet characteristics and operational conditions. The plan will encompass lifecycle costs as well as emission reductions compared to diesel-powered buses using alternative fuels; additionally it can measure vehicle performance along designated routes.

    Electric Vehicles

    An increasing number of people are opting to drive electric vehicles (EVs) as an environmentally-friendly transportation alternative. EVs run on electricity stored in their batteries and produce no tailpipe emissions, significantly cutting air pollution and greenhouse gas (GHG) production. Furthermore, technology surrounding EVs continues to advance – new battery technologies have increased range while charging times are becoming shorter, making EVs even more practical than ever.

    Cities and businesses alike are taking steps to reduce their environmental impact as more people opt for electric vehicles (EVs). One bus rapid transit system in Guangzhou, China reduced carbon dioxide by 86,000 tons within its first decade of operation alone! Furthermore, public transportation systems are turning toward renewable sources like wind or solar to power their buses and trams fleets.

    Greener vehicles are revolutionizing the logistics industry, particularly through electric and autonomous delivery vehicles. Amazon and UPS are investing in electric vans as an environmentally-friendly alternative to diesel-powered vans for last mile delivery, cutting carbon emissions and fuel costs while making deliveries in cities with lots of charging stations.

    Change towards eco-friendly transportation will take time; some individuals still may resist changing from cars to public transit or biking despite its obvious advantages. Employers can encourage employees to use sustainable forms of transport by offering incentives like reimbursements, free transit passes or carpool discounts as a way of showing employees they care about the environment and are taking measures to minimize their impact. Furthermore, companies can invest in telematics solutions which monitor vehicle performance and driver behaviors real time, in order to identify areas for improvement and identify opportunities for change.

    Bike Share Programs

    Bike share programs offer an eco-friendly solution to transportation by helping to lower emissions from vehicles while simultaneously encouraging active modes of travel – both of which have beneficial effects for public health and the environment.

    These systems work by offering people access to a fleet of bicycles for up to an hour at a time, returning them at any station within their bike-sharing network and becoming ever more popular worldwide.

    Studies conducted recently revealed that cities with active bike-share programs experienced less congestion and air pollution, as well as reduced fatalities and injuries from traffic accidents. Furthermore, these programs tend to be cheaper than driving or taking taxis.

    Although bike share programs bring many benefits, they do present certain challenges. Bike share companies have been accused of having an adverse impact on the environment; as well as vandalism and public backlash which forced some companies to pull their bikes from service.

    However, there are ways to overcome these issues and ensure bike-share programs remain sustainable. For instance, using a non-profit organization as part of their management of bicycles could ensure that supplies remain under control without oversupply issues arising.

    Un effective strategy to ensure sustainable bike sharing programs is to make them accessible for everyone, such as by positioning bikes in neighborhoods of need or offering incentives to low-income residents, working with community leaders to explain why such programs will benefit their area, or improving bicycle infrastructure to create safer cycling environments.

    Carpooling

    No matter the state or type of school your school operates, encouraging carpooling between students and staff members is an eco-friendly transportation option that will benefit both them and our planet. Each carpool reduces air pollution, traffic congestion, fossil fuel consumption and greenhouse gas and toxin emissions significantly.

    Carpooling can be an economical and eco-friendly solution to transportation costs; not only will you save on gas but you can use all available seating capacity in your vehicle! If you live or work close together, carpooling may be an attractive solution to getting to work faster and at less expense than driving alone.

    Finding a carpool partner may seem difficult for some individuals. Luckily, there is now an increasing number of websites and apps dedicated to helping users locate potential carpool partners as well as tools that allow for scheduling and payment management. Carpooling not only saves money and lowers carbon emissions; but can also increase workplace satisfaction and foster teamwork between coworkers.

    Carpooling also benefits commuters by reducing wear and tear on their vehicle, which can be costly to repair and maintain. Sharing rides can save up to $500 annually in vehicle maintenance and fuel costs alone! Furthermore, by decreasing traffic flow on roads, carpooling reduces parking requirements at schools and businesses – an advantage in areas without public transit access or no available options at all! Utilizing an all-inclusive rideshare program such as easygreencarpools will give employees an eco-friendly alternative for single occupant commuter trips while simultaneously cutting parking space needs while simultaneously cutting employer-provided parking costs!

    Natural Gas

    Natural gas, specifically methane, is one of the cleanest-burning fossil fuels available today, producing far fewer greenhouse gases and emissions than diesel or gasoline vehicles, significantly improving urban air quality while saving public transport operators money due to its reduced costs. Switching public transport over to natural gas could provide enormous potential for greening our planet.

    Public transit buses powered by natural gas emit up to 25% less carbon dioxide (CO2) emissions compared to their diesel counterparts, leading to decreased pollution and greenhouse gases emissions as well as lower levels of harmful air pollutants such as particulate matter and nitrogen oxides that contribute to poor air quality.

    Natural gas provides an eco-friendly energy alternative that emits significantly less CO2. The United States boasts vast reserves of this eco-friendly alternative to other fossil fuels; an expanding pipeline infrastructure will increase access.

    Renewable natural gas provides another green transportation option, produced from organic waste products like animal manure and landfills. Clean Energy currently utilizes this form of natural gas to power more than 25,000 trucks, buses and refuse trucks nationwide every day!

    However, continuing our reliance on natural gas will still damage the climate. Scientists have demonstrated that methane leaks from natural gas supply chains have an even larger warming impact than previously assumed. Thus, it is imperative that we transition toward carbon-free sources like wind and solar as soon as possible while simultaneously using energy efficient appliances and driving hybrid or electric vehicles – this way we can reduce dependence on fossil fuels while mitigating catastrophic climate change.

  • 5 Ways to Get Involved in the Climate Crisis or Global Warming.

    5 Ways to Get Involved in the Climate Crisis or Global Warming.

    Global warming is at an all-time high and world leaders need to act now if we want to avoid irreparable damage to the planet.

    Scientists warn that if temperatures continue their current path, Earth could reach tipping points — irreversible environmental changes — which may prove devastating for people, wildlife and natural ecosystems alike.

    Adaptation to climate change impacts is vital in protecting lives, livelihoods, homes and communities while alleviating suffering for the most vulnerable people. Furthermore, adaptation helps save and enhance natural defenses like mangroves reefs and wetlands that act as natural barriers against extreme events.

    1. Get involved in your community

    The climate crisis is an international challenge that must be solved collectively. It impacts every community, individual and natural ecosystem around us – leading to weather extremes, natural disasters, rising sea levels, loss of biodiversity, food and water insecurity, health risks, economic disruption and displacement; also having an especially harsh effect on poorer communities worldwide.

    But we can take steps to address it by working together on practical local solutions. Community groups have already been formed to combat this problem, with people from different backgrounds coming together to create an environmentally-friendly economy that is equitable. Solutions range from encouraging companies to adopt green policies, supporting public lands and stopping offshore drilling.

    One key part of combatting climate change involves switching away from fossil fuels towards renewable sources like solar and wind energy, since keeping global warming below 1.5 degrees Celsius requires substantial emission cuts across the economy.

    Every person can make an impactful statement against climate change by taking simple, everyday steps – like switching to a green electricity provider, taking sustainable transportation options or reducing meat intake – which will all have positive ripple effects in society.

    Voting and supporting candidates who support climate justice are also crucial steps toward creating change. Doing so enables elected officials to pass laws limiting carbon emissions and forcing polluters to pay their fair share, or you can donate money directly to environmental nonprofits like Greenpeace that work in your region – especially smaller nonprofits which may not receive as much national publicity, yet still need funding in order to do their work effectively.

    2. Support a local sports team

    With increased focus on carbon emissions reduction, many sports teams have taken steps to minimize their environmental footprint. This may involve replacing plastic straws with biodegradable ones or encouraging fans to bring reusable cups. It could even involve setting up community recycling stations at stadiums so it becomes easier for fans to dispose of waste properly.

    No doubt about it: the planet is in trouble and climate change has become a rising concern. Scientists and activists alike are demanding immediate responses to this problem, prompting media reports to begin using phrases like ‘climate crisis’ to highlight climate change’s dangers while creating an urgency around this matter.

    Sponsoring a local sporting team can be an excellent way of showing your commitment to your community, while encouraging young people to engage with sport from an early age. Furthermore, this action may increase visibility among potential customers while simultaneously helping promote your business and expand customer reach.

    Some teams even host hit-a-thons or shoot-a-thons where fans can donate a set amount per hit or goal scored by players – it can be an exciting way to raise funds for their team while encouraging fans to come watch their favourite players! This can also be used as an effective way of engaging fans who come out just for this purpose!

    One way you can show your support for climate action is to reach out to politicians. There are several organizations offering templates on how to write engaging letters or emails directly to politicians highlighting why climate action matters for your city, region or nation.

    3. Go green

    There are various ways you can go green, from switching to a renewable energy provider or recycling more. While these individual actions are beneficial, we must go further by calling for policy change – telling our MPs, local councillors and city mayors we want climate action now!

    They can create policies to reduce carbon emissions and promote sustainable living, including green spaces, public transport, cycling infrastructure, air quality monitoring and waste management. They can introduce subsidies for clean energy sources while setting prices on carbon emissions to protect natural carbon sinks. Finally, they could invest in climate solutions that benefit everyone such as energy efficient homes, green jobs and local food production.

    Pressure must also be exerted upon them to back international climate action, particularly among developing countries who are most at risk from global warming’s effects. This requires them to commit to fair climate finance allocation, climate justice framework and an equitable transition path for low-carbon economies involving vulnerable communities.

    Ask them to commit to reducing their carbon footprint through small steps such as switching off lights and appliances when not in use, cutting down on meat consumption (one of the major polluters of our atmosphere), shopping locally, and purchasing paper products with 100% recycling content. And if they own investments or pension funds, join a growing movement among people to divest from fossil fuel companies by diversifying them with climate-friendly alternatives.

    Share what you are doing to motivate friends and family to take action as well. Doing this can disprove the myth that nobody cares about climate change, making it easier for others to take part too.

    4. Volunteer

    Joining a social movement focused on environmental activities can have an immense impact. There are plenty of environmental-focused groups out there – so find one that resonates with you and join! Some great options to begin include Youth Strike 4 Climate, Possible, The Woodland Trust, Conservation Volunteers, Extinction Rebellion.

    One of the easiest changes you can make to reduce your carbon footprint is eating less meat – not only is this good for the planet, but it’s much healthier too! Eating plant-based diets are one of the key ways of doing just that!

    Speaking with your MP or local councillor is another effective way of getting involved. They have the power to pass laws that will help address climate change. Activism on climate change should be of importance not just as a vote-winner but as part of creating healthy futures for their communities.

    Climate change is a global threat that will impact us all; however, there are solutions available that may help alleviate its adverse impacts – from saving forests to powering homes with renewable energy sources, from combatting deforestation to rewilding landscapes, blocking oil tankers to fracking sites or blocking oil tankers from crossing borders.

    But for these solutions to take effect, governments and corporations around the world must place climate change at the heart of their policies and business practices – this means confronting polluting industries head on while simultaneously working toward net zero emissions as quickly as possible.

    5. Make a difference

    There are various ways we can make an impactful statement; some more dramatic than others. It’s up to each of us as individuals, families and communities to decide how best we can contribute.

    It is evident that carbon emissions must be reduced and ecological restoration supported, with production and consumption patterns altered, low or zero emission transportation modes utilized, sustainable land management implemented and biodiversity protected and ecosystems conserved. Furthermore, we must enhance natural carbon sink capacity while increasing their resilience.

    One of the easiest things we can do to combat climate change is talk with our family and friends about it and educate them. Voting for politicians who take action against it is also crucial, so get to know your MP and local councillors – their decisions have an effect on green spaces, roads, cycling infrastructure, recycling bins, waste collection services and energy efficient homes – among many other issues.

    Make your voice heard and influence politicians by joining campaign groups such as Power for People. Take it a step further by switching your home energy provider to Good Energy or Ecotricity which both source their electricity from renewable sources.

    Saving water is another easy and efficient way we can contribute to environmental protection. Pumping, heating, and treating water consumes considerable energy; by cutting back our usage – such as taking shorter showers or only choosing energy-efficient appliances and fixtures – we can save energy while lowering greenhouse gas pollution levels.

    If your savings are currently invested with banks such as Triodos or Ecology Building Society, consider switching them over to more sustainable banks like Triodos or Ecology Building Society that invest in renewable initiatives instead of fossil fuel projects.

  • Climate Change and Climate Crisis – What can we do to make a difference?

    Climate Change and Climate Crisis – What can we do to make a difference?

    At some point in their childhoods, almost every child will encounter climate change hazards like air pollution, cyclones, disease and heatwaves; those in poverty tend to bear the brunt. Such threats threaten vital services like clean water supply, nutritious meals and secure shelter that are integral components of child wellbeing.

    Humans are contributing to global temperatures rising by burning fossil fuels such as coal, oil and gas which emit greenhouse gases that trap solar heat within Earth’s atmosphere and cause it to build up over time.

    What is climate change?

    Climate change occurs when Earth’s natural processes shift, altering everything we depend on – from global temperatures rising to weather patterns shifting and sea level rise. Climate change is caused by humans adding heat-trapping gases such as carbon dioxide to the atmosphere via activities like burning fossil fuels for factories, cars and airplanes, clearing forests or using agricultural land for growing crops.

    Gases blanket the Earth like a greenhouse, trapping solar radiation and warming it further. Some of these emissions come from forests and wetlands burning or when coal, oil and gas are burned for electricity production; others include methane, nitrous oxide, CFCs and HFCs – chemicals used in refrigeration or aerosol sprays – along with CFCs/HFCs used in refrigeration or aerosol sprays used throughout refrigerators or aerosol cans used in refrigerators – CFCs/HFCs have increased temperatures worldwide by over one degree Celsius since 1900 due to these emissions.

    Warming due to increased greenhouse gases has had wide-reaching climate-related repercussions, including warming air and ocean temperatures; melting of Arctic, sea, and mountain glacier ice; changing rain patterns; and changes to wind, snowfall, and cloud cover.

    These climate change impacts are expected to worsen unless greenhouse gas emissions are reduced significantly. According to experts, keeping temperature increases below 1.5 degrees Celsius or even less is the optimal way to mitigate climate change impacts.

    Climate change affects people worldwide, from those displaced by storms and floods to farmers whose crops fail due to changing weather patterns. Because the global climate is interdependent, impacts in one part can have far-reaching repercussions for everyone – for instance when food prices spike due to crop failures caused by drought. It is for this reason that climate change needs to be tackled collaboratively – hundreds of countries signed on to the Paris Agreement which pledges to limit future climate change while strengthening energy security.

    Why is climate change happening?

    Scientists overwhelmingly acknowledge that human activities are driving climate change and already causing negative consequences worldwide. Burning fossil fuels such as coal, oil and natural gas emits vast quantities of greenhouse gases – such as carbon dioxide (CO2). This heat trapping effect traps solar heat on Earth to raise temperatures around 1 degree Celsius worldwide since 1904.

    These warming trends will only worsen without significant reductions in greenhouse gas emissions, and it would be wise to limit temperature rise to 1.5C to reduce most of its harmful impacts and avoid passing so-called “tipping points”, where changes accelerate beyond what would normally be deemed safe.

    Climate change presents many risks for all species and humans alike, from rising temperatures and extreme weather events that disrupt habitats to altered food sources and migration routes, all the way through to changing ecosystems that support life on this planet.

    Climate change poses serious health and economic threats for humans. Rising temperatures increase the incidence of heat-related illnesses like heart and lung disease; air pollution caused by wildfires or climate change-related pollutants exacerbates respiratory ailments like asthma or hay fever; rising sea levels threaten coastline communities with flooding and erosion; more intense storms may damage critical infrastructure resulting in population displacement;

    Climate change impacts every community differently; those with more resources may be better able to shield themselves from certain impacts and adapt accordingly, while climate crises disproportionately afflict low-income and marginalized people worldwide.

    Climate change exacerbates existing inequalities. While wealthy nations have historically produced most greenhouse gas emissions, they’re also at least partly responsible for its costs and effects – especially as our planet warms, especially those living in low-income or Indigenous communities, or those relying on natural resources like fisheries or forests that are being degraded by global warming events. As our planet heats, those most at risk will bear its consequences the hardest – including those dependent on these natural resources like fisheries or forests which are being degraded due to global warming events.

    What are the impacts of climate change?

    Climate change is already having a global impact, negatively affecting human health and well-being. As temperatures increase and temperatures reach dangerous “tipping points”, which define how much warming Earth can take without suffering negative repercussions like biodiversity loss, water shortages or rising sea levels.

    Globally, climate change has already had devastating consequences, decreasing food production and fueling hunger and malnutrition. Furthermore, freshwater availability is falling drastically, increasing water-borne disease risks, as well as damaging homes, roads and infrastructure with floods and storms.

    Climate change is making accessing healthcare services increasingly challenging. Over 930 million people – roughly 12 percent of the global population – currently spend at least 10 percent of their household income on healthcare costs, yet climate change threatens efforts towards universal coverage. Climate shocks due to heatwaves, droughts, floods or wildfires exacerbate existing barriers and make life even harder for some communities, leading to poverty or increasing health disparities between and within populations.

    People living in poor nations that have contributed less to climate change are particularly susceptible to its impacts, as they lack resources necessary to respond and adapt. Their livelihoods also rely more heavily on an intact natural environment as many work in agriculture or other ecosystem-based economies.

    Climate change exacerbates existing inequalities by compounding existing disparities and disproportionalities, especially between low-income communities and communities of color. Droughts and flooding may wreak havoc with food supplies and access to medical services; droughts increase mortality rates, restrict crop yields and lead to decreased human productivity – leading directly to more disparate treatment of vulnerable groups such as vulnerable communities of color.

    Good news is that we possess both the technology and expertise to dramatically lower carbon emissions and stop climate change. While achieving this will take international cooperation and transformational actions, it is doable and necessary if we want to avoid climate change’s worst impacts and protect natural systems for generations to come. It is time for real, immediate, transformative action!

    What can we do to make a difference?

    Over 97% of scientists agree that human activities are responsible for climate change – burning fossil fuels like coal, oil, and gas as well as cutting down forests (which play an integral part in maintaining global carbon management systems) to produce greenhouse gases such as CO2. Such greenhouse gases trap solar heat in the atmosphere and cause global warming by trapping heat in its orbital path before dispersion back onto Earth; furthermore they cause glaciers and ice sheets to melt, sea level rise, and changes to rainfall patterns.

    Climate change impacts us all; its impacts include more frequent and intense heat waves, reduced availability of fresh water and food supplies, biodiversity loss acceleration and conflict over land resources that drives mass migration as well as international peace and security threats.

    The global community has reached consensus that warming should not exceed 1.5 degrees Celsius, otherwise its consequences – such as heatwaves, flooding, drought, water shortages, wildfires, species extinction and crop failures – become harder to manage.

    Countries must act immediately to halt climate change’s harmful impacts, by ramping up efforts to cut emissions by setting more aggressive reduction targets and investing more heavily in renewable energy sources. They should also support developing countries in doing the same by sharing knowledge, expertise and financial assistance.

    Human health is also vulnerable. Climate change endangers essential ingredients of good health – clean air, safe drinking water, nutritious food supply and adequate shelter – and makes disease more prevalent. Malnutrition, diarrhoea and malaria become even more pervasive due to climate change; decades of progress made towards public health initiatives are at stake due to this threat.

    Reversal of current trends is imperative, with countries making an immediate commitment to shift away from fossil fuels and stop wasting precious time. It is both morally and economically imperative to act now – failing to do so, future generations may pay an even higher price than anticipated.

  • The Carbon Culprit – Understanding the Role of CO2 in Climate Change

    The Carbon Culprit – Understanding the Role of CO2 in Climate Change

    The greenhouse gas carbon dioxide blankets Earth’s atmosphere, preventing heat energy from escaping. That extra heat raises temperatures, warming the planet and disrupting nature’s usual balance.

    This animation, by Carbon Brief, shows national responsibility for historical emissions. It ranks nations by their total cumulative CO2 emissions from fossil fuels and land use change since 1850, including those emitted under colonial rule.

    1. The Carbon Cycle

    Carbon is a vital element for all living organisms and is found in various forms throughout the natural world. The carbon cycle describes the continuous circulation of carbon between Earth’s reservoirs – the atmosphere, oceans and soil. Carbon atoms are constantly moving between these reservoirs through processes such as photosynthesis, respiration and decomposition of living organisms, and volcanic eruptions.

    As greenhouse gases, carbon dioxide and other GHGs trap radiant energy from the sun within the atmosphere, warming the planet by increasing its average temperature. This is known as the greenhouse effect and it is essential to the existence of life on Earth, but it can become dangerous if concentrations of GHGs increase too much.

    GHGs are emitted into the air when carbon-containing matter is combusted, such as when fossil fuels like coal, oil and gas are burned. This causes CO2 levels in the atmosphere to rise, which is then absorbed by the ocean and land, leading to a positive feedback loop that amplifies climate change.

    Normally, natural processes keep atmospheric CO2 levels in balance. However, since the onset of industrial times, human activities have caused a significant rise in CO2 levels. This is because burning fossil fuels releases carbon that’s been locked away in geological formations for millions of years, transferring it from the slow to the fast (biogenic) carbon cycle. This influx has led to excessive levels of atmospheric CO2 that the biogenic carbon cycle can’t cope with, and which is driving climate change.

    Figure 1 shows the long-term trend of atmospheric CO2 observed at Mauna Loa since 1958. While the trend is clearly upwards, there are also a series of wiggles within the data. These are caused by seasonal cycles in photosynthesis, which cause the levels of CO2 in the atmosphere to rise and fall each year.

    Human activity is causing CO2 levels to rise at a rate faster than they have in the past 3.6 million years, and this has triggered the climate change we are currently experiencing. This figure shows the total cumulative emissions of CO2 from human activities since 1850, broken down by country and source (in billions of tonnes). The breakdown includes fossil fuels, cement, land-use change and forestry.

    2. Fossil Fuels

    Fossil fuels are a group of non-renewable materials that can be burned to produce energy. They include coal, crude oil, natural gas and other hydrocarbons that formed from the fossilized remains of plants and animals.

    When fossil fuels are burnt they release carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat from the sun and cause the world to warm. They also disrupt the Earth’s natural climate processes. This is causing a number of problems, including ocean acidification, loss of biodiversity and severe weather events.

    In the United States, coal, oil and gas provide 81 percent of our energy. They are responsible for nearly three-fourths of the CO2 emissions from human activities since the beginning of the industrial revolution. Fossil fuels are a non-renewable resource, and waiting millions of years for new deposits to form is not an option. This means that we need to make a transition to renewable energy sources and increase efficiency in our existing buildings and vehicles.

    It’s important to understand who is responsible for emissions because of the global nature of our economy and the complex ways that countries trade with each other. Emissions accounts that take into account consumption give full responsibility to the people who use the products that are made with fossil fuels, and tend to reduce the total for major exporters. However, there are practical challenges to obtaining such accounts, which require detailed trade tables and have only been available for the years since 1990.

    A key issue is that countries themselves are arbitrary boundaries, created by accidents of history, geography and politics. This makes it difficult to compare the historical responsibility of different nations.

    One way of looking at this is to use a method called “normalisation”. This involves splitting total emissions into categories according to the population of each country. This allows the share of a country’s emissions to be compared across countries with very different populations.

    Carbon Brief has normalised country shares using the historical timeseries published by CDIAC and aggregated with other useful information by Our World in Data (OWID). The chart below shows the 20 largest contributors to cumulative emissions (1850-2021) and also breaks down the total into those from fossil fuel use and land-use change and forestry (green). A further chart shows these breakdowns for each of the years since 1990.

    3. Energy

    The energy we use to do work — like walking, cycling, driving cars and trucks, running factories and ships, and baking bread in ovens — depends on the chemical energy of fossil fuels. But this energy isn’t free — it comes with a cost in the form of greenhouse gas emissions.

    Historically, fossil fuels have been the primary source of human-caused CO2 emissions. But a growing proportion of global energy consumption now stems from renewables and nuclear power, which are less carbon-intensive than fossil fuels. The renewables and nuclear sectors also produce fewer other types of harmful greenhouse gases, such as methane, nitrous oxide and sulfur dioxide.

    It’s important to understand that there is a direct link between the total amount of CO2 humans release and the planet’s warming – and that it doesn’t matter if those emissions happen now or in the past. This is because the climate system is a long-term player, with impacts that persist far beyond our own lives.

    The carbon cycle has natural’sources’ and’sinks’ for CO2. Volcanoes belch CO2 into the atmosphere, but a broader system of plants, oceans, and soils absorb and store it. Over time, the carbon sinks replenish themselves, but the rapid pace of human activity has overwhelmed them.

    For this reason, the global climate system now has a ‘carbon budget’ that determines how much further the world can warm before it goes too far. This budget is the total amount of CO2 humans have already released into the air. If emissions continue at current levels, the budget for a two-thirds chance of keeping temperatures below 1.5°C would be used up within 10 years – and the remaining two-thirds chance in 2050.

    Countries can take steps to reduce their historical emissions by using renewable and nuclear energy sources, and reducing their transport and heating and cooling demand. They can also invest in clean energy technologies, such as carbon capture and storage, which involves capturing the CO2 from fossil fuels before they enter the atmosphere, and storing it deep underground at a suitable geologic formation.

    It’s also important to recognise that a country’s ranking in the chart above – and its per-capita ranking – depends on the methodology chosen. While Carbon Brief’s approach to normalising a country’s ranking by population is fairly straightforward, other methods can lead to markedly different results and should be considered carefully.

    4. Renewable Energy

    The rise in atmospheric CO2 is largely due to human activities. The burning of fossil fuels such as coal and oil, and deforestation have added a significant amount of heat-trapping greenhouse gases to the atmosphere. These gases trap the Sun’s heat in the atmosphere and change the climate.

    Scientists are working on ways to reduce these changes by developing renewable energy sources. One way is to turn carbon dioxide into a useful fuel substitute by using it as raw material in the production of biofuels like ethanol and biomass. Another method is to capture the CO2 produced when fossil fuels are burned and store it deep underground.

    These methods have the potential to slow, halt and even reverse global warming. But the key to a successful outcome will be implementing them on a large scale. This includes replacing a substantial proportion of cars with zero-emission vehicles, and providing access to clean energy for all, including remote, island and coastal communities.

    Renewables such as wind and solar photovoltaics (PV) are increasingly popular, and the technology continues to improve and get cheaper every year. They are a vital part of the solution to climate change, but they will need to be matched by increased deployment of nuclear power and other low-carbon technologies, along with better batteries to store energy.

    Observed changes in the Earth’s climate system, such as rising global air and ocean temperatures, melting of snow and ice, and long-term sustained reductions in regional weather patterns, are caused by extra heat being added to the atmosphere by humans through the use of fossil fuels, land-use change, agriculture, and deforestation. These human-caused inputs increase the concentration of heat-trapping greenhouse gases in the atmosphere.

    The US is responsible for the highest total cumulative emissions of CO2 since 1850, as shown in this animation from Carbon Brief, which also ranks countries by their contribution to the global total and separates them into emissions from fossil fuels and land-use change/forestry.

    A recent study has suggested that adding genetically modified E coli bacteria to sugar cane fields could make the plant produce three-fourths as much ethanol per hectare, and thus emit less CO2. This would reduce the need to harvest sugar cane for ethanol and cut the rate of deforestation in tropical nations where it is harvested.

  • Deforestation Dilemma – The Alarming Impact on Climate Change

    Deforestation Dilemma – The Alarming Impact on Climate Change

    Human consumption, population growth and global trade have created a demand for natural resources that exceeds what the earth can replenish. Deforestation and forest degradation are key causes of this climate change imbalance.

    People depend on forests for food, water, medicine and wood. When forests are lost or degraded, it sets off a chain of events that affects life both locally and around the world.

    Soil Erosion

    When land becomes eroded, the top layer of soil, which is high in organic material, loses its fertility. It is carried away by wind or water and deposited elsewhere. Erosion reduces cropland productivity and can even lead to the pollution of nearby waterways, lakes and wetlands. This erosion process is most accelerated by human activities, including overplowing and unsustainable agriculture methods.

    Farming practices, especially tillage and the use of fertilizers, contribute to erosion. In addition, grazing animals also destroy the soil through their feeding habits. Erosion also increases with weather extremes, such as heavy rainfall and snowmelt. Moreover, bare lands are more vulnerable to erosion because they lack the protective cover of vegetation and the ability to retain moisture and nutrients.

    The speed of soil erosion depends on the weather and soil characteristics, such as aggregation, infiltration, ground cover and slope. In general, more textured soils with high organic matter are less susceptible to erosion than sand and gravel-based types. In addition, knolls and shoulder slopes experience more erosion than flat areas because they have greater surface friction.

    There are different types of soil erosion, mainly by water or wind. Sheet erosion, for instance, occurs evenly over a uniform slope and usually goes unnoticed until most of the productive topsoil has been eroded. It is usually accompanied by changes in soil color, reduced crop yield and deposition at the bottom of the slope. Other indicators of sheet erosion include lighter-colored soils on knolls and shoulders, change in the thickness of soil horizons and low crop yields.

    When eroded soil is washed away by rain or runoff, it can pollute waterways. This dirty water contains harmful chemicals such as pesticides and fertilizers. It also clogs grassed waterways and dams, which can increase flooding and siltation.

    In addition to this, the contaminated dirt that makes it to the waterways can also cause harmful algal blooms and poison drinking water. Moreover, the soil particles can be inhaled by humans and livestock, causing lung diseases. Eroded soil also loses its ability to hold moisture, which reduces the growth of plants and crops.

    Water Pollution

    Deforestation impacts water quality in a variety of ways. Without trees to hold the soil in place, erosion carries dirt and other debris into rivers and streams. When this material combines with organic materials such as leaves, woody debris and sewage, it is carried long distances into lakes and estuaries, resulting in water pollution. This water pollution can have a direct impact on climate change by altering the flow of greenhouse gasses, such as carbon dioxide, into the atmosphere.

    Tropical forests are the source of most deforestation, as people clear them to use the land for logging, cattle ranching, oil palm and rubber tree plantations, and mining. The practice of slash and burn farming, which involves burning swaths of forest to prepare the land for planting, is an important factor as well. The fertile soil resulting from this process can quickly wash into rivers, however, and is then used for growing other crops that are unable to hold the land in place and contribute to further soil erosion.

    The loss of forest vegetation also impacts biodiversity. Forests are home to an incredible array of animal and plant species, many of which are unique and exist only in small geographic areas. The loss of these forests can lead to their extinction.

    Climate change is causing changes in rainfall patterns that will challenge farmers and natural ecosystems alike. The resulting changes in water supply will affect drinking water, crop production and property values, not just in the United States but around the world.

    As the planet’s water resources become increasingly stressed, it is critical that we take action to mitigate climate change and conserve our Earth’s dwindling forests. The key to preventing the worst effects of global warming is to understand how all of these environmental issues are linked. As we learn more about the interactions between these disciplines, we will be able to develop solutions that will save lives and protect our environment.

    Greenhouse Gas Emissions

    Since 1750, the amount of greenhouse gases like carbon dioxide in the atmosphere has increased by 47 percent. When these gases are released, they create an insulating blanket around the Earth and trap more heat from the sun inside our atmosphere. This extra heat raises global temperatures, a phenomenon called climate change.

    The most common source of human-caused, or anthropogenic, emissions is burning fossil fuels, including coal, oil, and natural gas to produce electricity and heat buildings. This accounts for about one-quarter of worldwide human-driven emissions. It’s also the largest single source of emissions in the United States, responsible for 28 percent of national emissions in 2021. These emissions also include small amounts of methane and nitrous oxide, along with the man-made fluorinated gases chlorofluorocarbons used in refrigeration and air conditioning.

    Forest fires, agricultural activities, and land use changes are the other major sources of human-caused greenhouse gases. The vast majority of these come from deforestation, with methane and nitrous oxide as significant contributors. These are called long-lived greenhouse gases, because their impact on warming lasts a much longer time than other gases, such as CO2. Because of this, when scientists report greenhouse gas emissions, they usually refer to them in terms of CO2-equivalent (CO2e).

    The transportation sector contributes to about another quarter of all U.S. greenhouse gas emissions, with gasoline and diesel fuel combustion producing the most emissions. These also include small amounts of methane and nitrogen oxide from vehicle air-conditioning and refrigerant systems.

    Climate scientists and environmental advocates agree that the best ways to reduce greenhouse gas emissions are to stop deforestation, move to renewable energy, and improve efficiency in residential, commercial, and industrial buildings. This includes replacing older, less-efficient equipment with more efficient models, using advanced technologies, and shifting to lower-emission power plants.

    Other important strategies for cutting greenhouse gas emissions include capturing carbon as it enters the atmosphere as a byproduct of fossil fuel burning and transporting it deep underground in carefully selected and suitable geologic formations, where it’s safely stored away. This method of carbon capture and storage is often called “geological sequestration.” EPA’s ENERGY STAR program helps Americans save money and reduce their greenhouse gas emissions by promoting the purchase of a wide range of energy-saving products, from appliances to home insulation to commercial roofing.

    Species Loss

    Species that live in forest habitats such as birds, mammals and insects need forest cover to survive. When forests are cut down, those species lose their homes. As a result, their numbers drop and some species are driven into danger or even out of existence.

    Deforestation also drives climate change. Trees absorb carbon dioxide from the air through photosynthesis, locking it chemically in their wood. When they are logged and burned, the stored carbon is released into the atmosphere. This increases greenhouse gas levels and speeds up global warming.

    The same is true for other types of natural ecosystems, including peatlands and ocean habitats like mangroves. Preserving and restoring these ecosystems helps reduce greenhouse gases, which in turn slows down global warming.

    Earth’s climate is already changing dramatically because of human-caused emissions of heat-trapping greenhouse gases. The Earth’s temperature is rising, glaciers and ice sheets are melting, rivers and lakes are drying up, and plants and animals are shifting their geographic ranges to accommodate the changes.

    Climate change is causing more and more severe weather events, from extreme heat to heavy rains and flooding. These conditions are disrupting people’s lives and causing economic losses and social problems. People and places least able to adapt are being hardest hit.

    As the Earth warms, biodiversity is under threat in every region. Many species will disappear entirely from their native homes, and those that remain will struggle to adapt. As a result, ecosystem services that help sustain our quality of life are being lost, including water supply, food security and pollination.

    Biodiversity destruction is a triple planetary crisis. The world must tackle these issues together if we are to advance the Sustainable Development Goals and keep our planet viable for future generations. That’s why Earthjustice is fighting to protect iconic wildlife, from wolves and orangutans to wild turkeys and manatees, from hunters and poachers who threaten their survival, as well as fighting to limit deforestation and other forms of natural space degradation.

  • The Benefits of Plant-Based Diets: A Sustainable and Healthy Lifestyle

    The Benefits of Plant-Based Diets: A Sustainable and Healthy Lifestyle

    Plant-based diets have been growing in popularity over the past few years as people become more conscious of the environmental impact of food choices and the potential health benefits of a plant-based lifestyle. A plant-based diet consists of a wide variety of foods, such as fruits, vegetables, whole grains, legumes, nuts, and seeds, and excludes meat, dairy, and other animal products. In this article, we will explore the benefits of plant-based diets and why they are considered sustainable and healthy lifestyle choices.

    The Benefits of Plant-Based Diets for Health

    1. Reduced Risk of Chronic Diseases: One of the most significant benefits of a plant-based diet is its potential to reduce the risk of chronic diseases. Studies have shown that plant-based diets are associated with a lower risk of heart disease, type 2 diabetes, high blood pressure, and certain types of cancer. The high fiber, nutrient-dense content of plant-based foods, combined with the absence of saturated fats and cholesterol found in animal products, makes them an excellent choice for reducing the risk of chronic diseases.
    2. Weight Management: A plant-based diet can also help with weight management. The high fiber content in plant-based foods can help individuals feel full and satisfied while consuming fewer calories. Additionally, plant-based diets tend to be lower in fat and calories than diets high in animal products, making them an effective tool for weight loss and management.
    3. Improved Digestive Health: Plant-based diets are also associated with improved digestive health. The high fiber content in plant-based foods promotes regular bowel movements and can prevent constipation. Additionally, some research suggests that plant-based diets may reduce the risk of inflammatory bowel disease.
    4. Improved Nutrient Intake: Plant-based diets can provide better nutrition compared to diets high in animal products. Plant-based foods are rich in vitamins, minerals, and antioxidants that are essential for maintaining optimal health. By consuming a variety of plant-based foods, individuals can ensure they are meeting their nutritional needs.

    The Environmental Benefits of Plant-Based Diets

    1. Reduced Greenhouse Gas Emissions: Animal agriculture is a significant contributor to greenhouse gas emissions, which contribute to climate change. Plant-based diets, on the other hand, have a much lower carbon footprint and can help reduce greenhouse gas emissions. By reducing our consumption of animal products, we can help reduce the environmental impact of our food choices.
    2. Conservation of Natural Resources: Animal agriculture requires large amounts of water, land, and other resources. By reducing our consumption of animal products, we can conserve these resources and reduce our impact on the environment. For example, it takes approximately 1,800 gallons of water to produce one pound of beef, whereas it takes only 220 gallons of water to produce one pound of tofu.
    3. Reduced Deforestation: The production of animal products also contributes to deforestation, as forests are often cleared to make way for grazing land and feed crops. Plant-based diets can help reduce the demand for animal products and, in turn, reduce deforestation. By choosing plant-based options, we can help protect natural habitats and promote biodiversity.

    Tips for Adopting a Plant-Based Diet

    If you are interested in adopting a plant-based diet, here are some tips to help you get started:

    1. Start Slow: It can be overwhelming to completely overhaul your diet, so start by incorporating more plant-based meals into your routine. Begin by swapping out one meal a day with a plant-based option, and gradually increase the number of plant-based meals you consume.
    2. Experiment with New Foods: There are many delicious plant-based foods out there, so don’t be afraid to try new things and experiment with different recipes. Explore different cuisines and ingredients, and have fun with your plant-based cooking.
    3. Make Sure to Get Enough Nutrients: When adopting a plant-based diet, it is important to make sure you are still getting all the nutrients your body needs. This includes getting enough protein, iron, calcium, and vitamin B12. While plant-based foods can provide these nutrients, it may be necessary to supplement your diet with fortified foods or supplements.
    4. Plan Ahead: Planning your meals in advance can help ensure that you are getting a variety of plant-based foods and meeting your nutritional needs. Meal prepping and cooking in bulk can also save time and make it easier to stick to a plant-based diet.
    5. Connect with Others: Joining a community of like-minded individuals can be a great way to stay motivated and get support as you transition to a plant-based lifestyle. Look for local groups or online communities where you can connect with others and share recipes, tips, and advice.

    Conclusion:

    In conclusion, plant-based diets offer numerous health and environmental benefits, making them a sustainable and healthy lifestyle choice. By reducing our consumption of animal products and incorporating more plant-based foods into our diets, we can improve our health, reduce our environmental impact, and promote a more sustainable future. Whether you choose to adopt a fully plant-based diet or simply incorporate more plant-based meals into your routine, the benefits are clear. So, why not give it a try and see how a plant-based lifestyle can transform your health and the planet?

  • The Importance of Sustainable Living: Creating a Better Future for Our Planet

    The Importance of Sustainable Living: Creating a Better Future for Our Planet

    Sustainable living is becoming increasingly important as we face environmental challenges such as climate change, deforestation, and pollution. By living sustainably, we can reduce our impact on the environment and create a better future for our planet. In this article, we will explore the importance of sustainable living and ways in which we can incorporate sustainable practices into our daily lives.

    What is Sustainable Living?

    Sustainable living is a way of life that aims to reduce our impact on the environment by conserving natural resources, reducing waste and pollution, and promoting a healthy and equitable society. It involves making conscious choices about how we consume and use resources, as well as being mindful of the impact our actions have on the planet and future generations.

    The Importance of Sustainable Living

    The importance of sustainable living cannot be overstated. We are facing unprecedented environmental challenges that threaten the health and well-being of our planet and its inhabitants. Climate change, deforestation, and pollution are just a few of the issues we are grappling with, and they require urgent action.

    By adopting sustainable practices, we can reduce our impact on the environment and help mitigate these challenges. Sustainable living promotes the conservation of natural resources, such as water and energy, which are essential to the functioning of our planet. It also reduces waste and pollution, which can harm ecosystems and wildlife.

    Additionally, sustainable living can promote social and economic equity. By prioritizing sustainability, we can ensure that resources are distributed fairly and that everyone has access to clean air, water, and food.

    Ways to Incorporate Sustainable Living into Our Daily Lives

    Incorporating sustainable practices into our daily lives is essential if we want to create a better future for our planet. Here are some ways in which we can do this:

    Reduce, Reuse, and Recycle

    One of the most effective ways to reduce our impact on the environment is to reduce our consumption and waste. We can do this by reusing items, recycling materials, and choosing products with minimal packaging.

    Conserve Energy

    Reducing our energy consumption is another important way to live sustainably. We can do this by turning off lights and appliances when they are not in use, using energy-efficient light bulbs and appliances, and reducing our dependence on fossil fuels.

    Choose Sustainable Products

    Choosing sustainable products is another way to reduce our impact on the environment. This includes products that are made from renewable resources, such as bamboo or recycled materials, as well as products that are made in an environmentally responsible manner.

    Eat a Plant-Based Diet

    Eating a plant-based diet is not only good for our health, but it is also good for the environment. Plant-based diets require fewer resources to produce than animal-based diets, and they produce fewer greenhouse gas emissions.

    Use Alternative Transportation

    Reducing our dependence on cars and other fossil fuel-powered vehicles is essential if we want to reduce our impact on the environment. We can do this by using public transportation, cycling, or walking whenever possible.

    Support Sustainable Practices

    Supporting sustainable practices is another important way to live sustainably. This includes supporting companies and organizations that prioritize sustainability, as well as advocating for policies that promote sustainability at the local and national level.

    The Benefits of Sustainable Living

    Living sustainably has numerous benefits, both for the environment and for ourselves. Here are just a few of the benefits of sustainable living:

  • Countries Affected by Rising Sea Levels

    Countries Affected by Rising Sea Levels

    Several countries are currently experiencing the effects of rising sea levels. This includes Kabul and surrounding areas in Afghanistan, New York City, and Miami Beach. These countries are all undergoing floods and atolls are also in danger. In addition, there are conflicting claims to the ocean’s resources and rights.

    Flooding in Kabul and surrounding regions

    During the past 30 years, the water supply in Afghanistan has suffered from the effects of drought, flooding, and desertification. These effects are due to the combination of climatic changes, a decrease in rainfall, and the deforestation of land. It is essential to find ways to preserve the river water for the future.

    The Kabul River, which forms part of the Kabul River System, rises in the mountains of central Afghanistan. It flows north to Pakistan and eventually joins the Indus River near Attock. The water of the Kabul River supports over 300,000 ha of intensively irrigated areas in Afghanistan. During recent drought years, the Kabul River has run dry several times.

    The Kabul River has a flow of 33 to 460 m3/s. However, this is not enough water to reach the aforementioned Amu Darya. In fact, all other rivers in northern Afghanistan have insufficient water to make it to the Amu Darya. The Kunar River, a tributary of the Kabul, provides much of the flow in lower Kabul.

    Flooding in New York City and Miami Beach

    During the last century, the global mean sea level has increased by about 8-9 inches. That’s not much, but it’s up from about 0.06 inches per year in the early part of the century. And that rate has accelerated. It has jumped to 0.14 inches per year since 2006.

    A report by the National Oceanic and Atmospheric Administration (NOAA) found that in the next 30 years, the seas in the United States will rise by about 10 inches. And that means coastal flooding is going to happen.

    And that’s bad news, especially in places like New York City and Miami Beach. These cities are in coastal Florida, and the sea level rise there is a real threat to their neighborhoods.

    There is also the problem of the storm surge. When a hurricane hits, the seas rise, and the surge travels inland. It can damage homes and businesses. It’s worse when the storm is a bigger storm with stronger winds.

    Flooding in Atolls

    Coastal regions that are exposed to sea level rise face a high risk of storms and floods. These events can be damaging to buildings, crops, and other infrastructure. The risk is particularly high when a large storm or tidal flood occurs. These events can also contaminate freshwater reserves and lead to salt water intrusion. Coastal defenses, including mangroves, can prevent wave overwash.

    Sea level rise is a significant stressor for coastal island nations. It has been estimated that global sea levels will increase by 3 to 4 millimeters per year over the next couple of decades. This is expected to increase the frequency and severity of coastal flooding. It also has the potential to make many islands uninhabitable by 2050.

    Among the coastal regions that are most sensitive to climate change are coral atoll islands. These atolls are small areas of land that sit a few metres above sea level. In recent years, coral atolls have grown larger in size. However, they have also remained stable.

    Conflicting claims to ocean resources and rights

    Maritime boundary disputes are becoming increasingly important for states in the 21st century. They are not simply political issues, but often reflect locality-specific realities, worldviews, and management regimes.

    This article explores transformations in ocean conflict, focusing on four issue areas: maritime spatial planning, conflicting claims to ocean resources, rights of countries affected by rising sea levels, and ocean reconciliation. It suggests that this problem is unlikely to be resolved until radical ocean governance is applied.

    These changes are driven by exogenous forces such as climate change, blue growth, and the rush to capitalize on ocean resources. These factors challenge existing management regimes and lead to conflicting claims by nations. The resulting ocean conflict thwarts efforts to implement the Agenda 2030 Sustainable Development Goals.

    These changes are also driven by locality-specific dynamics such as state-initiated marine spatial planning and socio-environmental interactions. Conflicts may also flare up after big traumatic events. In the case of the South China Sea, tensions are strained between China and Vietnam.

  • Can We Stop the Deserts From Spreading?

    Can We Stop the Deserts From Spreading?

    Despite the fact that the continent of North America is a relatively flat area, there are still regions that are prone to deserts. These regions are known as the Interior, Coastal, Subtropical, and Polar regions. These regions are all very different from each other, and it is important to understand them in order to properly combat the spread of deserts.

    Subtropical

    Having a dry climate has been an enduring problem for humanity, but can we stop them from spreading? Scientists from UMD and MIT studied the movement of the planet’s arid zones and found that there is a direct link between the expansion of arid zones and the climate change we’re experiencing. It’s also worth noting that the results of the study may have important implications for other deserts as well.

    For example, researchers found that dry air is moving poleward from the south, and could soon make its way to the Alps and the Mediterranean. This could lead to less snowfall in the Alps, and could even cut winter rain in the Mediterranean.

    Another interesting discovery is that the Sahara’s expansion has actually increased its average seasonal area. The Sahara is one of the driest places on the planet. The expansion is believed to be caused by the Hadley circulation, a circulation pattern that sends dry air northward from the south and produces downpours. The largest expansion of the Sahara occurred in summer, with the largest expansion being 16 percent.

    The study was also able to show that the odometer may be the most important metric to measure the arid zone’s effect on climate. Researchers used satellite measurements to look at the lower atmosphere, and found that the smallest temperature change was in the tiniest molecule. These findings suggest that global warming may be behind the changes.

    Coastal

    Various nations are working on ways to slow the spread of deserts. These include efforts to conserve water, enhance biodiversity, and improve crop yields. The Great Green Wall, a project begun in 2007 in the deserts of Senegal and Djibouti, was intended to form a natural barrier to the Sahara. But it failed to live up to its promise.

    One of the more effective attempts to stop the spread of deserts is to create windbreaks using trees. These trees not only break the wind force, but also anchor the soil. This is a particularly important consideration in regions where soil compaction prevents water from soaking into the ground.

    Another is the invention of the solar panel, which spares villagers from having to pay more for water in the desert. It can pump water from a communal well and spares the farmers from having to buy expensive pumps for their farm.

    The world’s largest sand desert is the Sahara Desert. It has been expanding at an accelerated rate since the 1950s, and it’s been estimated that over 300 million metric tons of topsoil are being lost each year. However, in order to fully reclaim sand dunes for agricultural purposes, it will likely require a significant amount of research and development.

    In the deserts of Western China, Central Asia and even the Middle East, the number of people living in areas without adequate rainfall is on the rise. The global weather cycle is responsible for some of these changes. In some regions, the drought-prone sands of the Sahara are threatening to overwhelm the indigenous grassland habitats.

    Rain shadow

    Whenever air moves over a mountain range, a rain shadow can form. This phenomenon explains why some areas are wet while others are dry. Depending on the region, rain shadows can be extremely strong or weak.

    Rain shadows are formed because mountain ranges act as barriers to airflow. The slopes of these mountains push clouds up into colder air, resulting in less rainfall on the other side. Some famous deserts are located on the leeward side of mountains.

    Mountain ranges also block sub-tropical trade winds, which originate in the southern hemisphere. These winds originate from the Pacific Ocean and cool down over the mountains. This causes moisture to be lost in the form of precipitation, condensation, and heat loss.

    Rain shadows can also be formed along coastlines where cold oceanic upwellings cause moisture loss. Deserts can also form in inland regions far from coasts. The Andes Mountains in South America form a rain shadow, resulting in a drier climate. Similarly, mountains in the Himalayas in Asia cause a drier climate. The Gobi Desert in Mongolia is another example of rain shadows.

    Rain shadows can also occur on the side of mountains near the Appalachian Mountains, the Rocky Mountains, and other prominent ranges. Some mountains can have rain shadows that extend for hundreds of miles. The effect can be even more pronounced if the mountain range is tall.

    Interior

    Unlikely to behold, the sun and moon may have ejected their ilks to the dust bins o’ the mist. One thing to watch out for is the aforementioned sands. To be sure, if you have the foresight to not have been sand blasted off your digits, you are out of luck. The following are a few notable exceptions. Those aforementioned sand savors may be the deeds to come, a boozed up doodoo in your near future. A good way to keep your sanity intact is to not engage in such activities. The best way to do this is to make the effort a top priority.

    Polar

    During the last two decades, we’ve witnessed a massive rate of desertification across the globe. While this phenomenon is not new, it’s become a global threat. It’s estimated that there are currently over six million square kilometers of the world’s surface that are unsuitable for farming. It is also estimated that, globally, there are over a billion people living in areas of low or no rainfall.

    The question is, how can we prevent desertification from spreading like the plague? Fortunately, there are a number of measures we can take to improve the situation. The first is to prevent desertification from occurring in the first place. This requires a concerted effort on the part of national governments, businesses and individuals. In a bid to curb the spread of the desert, countries across the globe have launched initiatives to prevent this phenomenon from reoccurring.

    The Sahara, in particular, is a major source of concern. During the last two decades, the desert has pushed southward by more than a hundred kilometers. While the Sahara isn’t yet affecting the rest of Africa, it’s definitely a threat to the continent’s livelihoods.

    The Gobi Desert, on the other hand, has already swallowed up whole villages. It is also the driest place on Earth. In addition to destroying habitat, it also forces thousands of people to relocate. In fact, it is the fastest growing desert on Earth.

    Reforestation

    Almost a third of the Earth’s surface is now desert. The Gobi Desert, located in northwest China, is the fastest growing desert on the planet. It consumes grasslands and forces thousands of people to move out of their villages. Its size is already 1.2 million square kilometers.

    The Sahel, in the western part of Africa, is turning into a desert. The region is arid and drought is accelerating the desertification process. A group of 21 African nations has launched a plan to combat desertification and improve lives in the Sahel.

    The Great Green Wall is an ambitious project to restore land. It would stretch across Africa, from Senegal to Djibouti, and would create an 8,000-kilometer mosaic of vegetation. The plan also aims to create 10 million jobs in rural areas.

    The project has received a boost from the World Bank. It is estimated that planting 2 billion acres of trees would reduce carbon dioxide emissions by two-thirds. This will increase rainfall and recharge aquifers. In addition, vegetation can absorb water and retain it in the soil. Planting trees is one of the many steps to combat desertification.

    The Sahel region is the most vulnerable to desertification. It has a very rocky surface, and it is prone to frequent and severe droughts. It has been turned into a desert by heavy grazing by livestock. Planting trees will improve the water table. Planting trees also can help reduce runoff.

  • Rising Sea Levels and Bangladesh’s Economy

    Rising Sea Levels and Bangladesh’s Economy

    Despite the fact that rising sea levels threaten Bangladesh’s economy, there is a way to mitigate this effect. It is called Climate Prosperity. This plan is being carried out by the government of Bangladesh in order to help the country develop in a more environmentally friendly way.

    Global sea levels have risen by about 20 cms (8 inches) since 1900

    During the last hundred years, the global mean sea level has risen by about 20 cms (8 inches). It’s not as impressive a figure as it sounds. However, in the last twenty years, the rate has increased.

    One of the factors responsible for the sea level increase is the thermal expansion of ocean water. In addition, land based ice is melting due to global warming. Water is also being pumped out of groundwater aquifers.

    Another factor is land subsidence. This is caused by land movements and the withdrawal of fossil fuels. The amount of sea level rise will differ from region to region due to local weather, land movement, and tides.

    Another factor is the melting of the Greenland ice sheet. This has contributed to sea level rise since 1990. It’s likely that the amount of sea level rise will be higher in some parts of the United States than in others.

    The Intergovernmental Panel on Climate Change (IPCC) has issued a report that says human activity has been responsible for at least half of climate change during the last half century. It also says that global mean sea level could rise 1.1 meters above pre-industrial values by 2100.

    The blue line on the Earth map shows that sea level has risen by about 20 cms since 1900. It’s not as impressive a figure compared to the sea level changes of the past, but it’s still a very important fact.

    However, the most important factor in sea level is not the sea level itself, but rather the land subsidence that has occurred. There are many other factors that have caused sea level to rise, but this is one of the most important.

    Lower Ninth Ward is particularly vulnerable to sea level rise

    Coastal floods are regarded as the most dangerous natural disasters. Sea level rise is expected to increase the frequency and magnitude of floods. It will also affect the population living along the coasts. These changes will have a significant impact on the coastal ecosystem as a whole.

    The Coastal City Flood Vulnerability Index (CCFVI) provides insights into the future 2100 total flood risk on a coastal city scale. The CCFVI is a composite measure of three main aspects of a coastal city’s water drainage system. The indicator is also a measure of resilience.

    A CCFVI has a large role to play in helping city planners and policymakers to better understand flood risks and develop more effective strategies to mitigate them. To achieve the desired results, a multidisciplinary team should be consulted to discuss the most important factors to consider. In addition, it should also be considered in conjunction with other decision-making tools such as expert judgment and participatory methods with the local community.

    A CCFVI can also be used to identify trends in the development of an urban area. This is particularly important in the wake of hurricanes, where flooding is a constant threat to low-lying coastal communities. In addition, it can inform local governments about the need to re-engineer their flood protection and drainage systems.

    There are more than nine coastal cities studied in this study. Each city was evaluated for the CCFVI and a number of other metrics pertaining to the same. Those selected are ranked in order of least to most vulnerable. The most vulnerable of these cities is Dhaka. The second most vulnerable is Calcutta. Those two cities will increase their respective vulnerabilities by a whopping 1.7, and 1.1, by 2100, respectively.

    Mangroves are halophytes trees that grow in saline water

    Besides being a source of salt, mangroves provide habitat for various species of wildlife. They are important sources of algae and fruit for coastal communities. They also help reduce wave energy. They are also spawning grounds for many ocean bound fish. They reduce flood risks for 15 million people each year. They also play an important role in conserving coastal areas.

    Mangroves grow in intertidal areas of tropical coastlines. These areas have low-oxygen conditions. Their root systems are unique. The outermost layer of the mangrove root has three parts. Each part has different morphologies.

    The outermost layer contains a porous membrane with pore sizes of hundreds of nanometers. These pores are irregularly distributed. They are used to filter out solutes. However, continuous water filtration can foul the membrane.

    Another layer of the mangrove root consists of tens of nanometer-scale porous structures. These structures help the root to prevent Na+ ions from entering xylem vessels. They also block the passage of apoplastic bypass ions.

    In addition to these specialized root systems, mangroves are also able to grow in freshwater. However, the mangrove’s ability to grow in freshwater is limited by competition from other plant species. This makes it difficult for the plant to grow in freshwater permanently.

    The mangrove’s morphological structure has evolved to withstand harsh environmental conditions. These plants are able to survive in low oxygen conditions, and they have special leaves to filter out salt from the water. They also have stilt roots that penetrate the soil away from the main stem. The stilt roots are able to act as breathing roots.

    The mangrove’s ability to filter salt out of sea water is important for the survival of the plant. In addition, the plants can help to desalinate high concentrations of saline water. In this way, they can help to restore saline soils.

    Climate prosperity plan to mitigate economic effects of global warming on Bangladesh’s economy

    During the 26th UN Climate Change Conference (COP26) in Glasgow, Scotland, Bangladesh is expected to present its “Climate Prosperity Plan” to the international community. The plan aims to reduce the impacts of global warming on the country’s economy. It also encourages other vulnerable countries to develop their own plans.

    The plan will seek to reduce the economic impacts of global warming on Bangladesh by promoting renewable energy, investing in agriculture, and developing wind farms along the coast. It also envisions building more resilient agriculture and restoring mangrove forests to protect the country’s coast. In addition, it will empower banks to offer favorable terms to projects that use fossil fuel-free energy.

    Bangladesh’s economy is expected to increase by a factor of two by 2030, but climate change could cause it to reverse that trend. According to the sixth assessment report of the Intergovernmental Panel on Climate Change, global warming of 1.5 degrees Celsius above pre-industrial levels would result in longer warm seasons and more intense heat events. The impacts would also affect food security in many regions. In addition, agriculture in Bangladesh and neighboring countries such as Pakistan could lose up to 50% of their crop yields by the end of the century.

    Bangladesh is considered to be the most vulnerable to climate change. Its southern coastal area is particularly vulnerable to the ill effects of global climate. In addition, the country is at risk of flooding and displacement due to cyclones.

    The country’s government has spent about two billion dollars annually on climate change adaptation measures. However, it is still unable to reduce its emissions with limited international support. Its emissions are estimated at 0.3 tons of carbon dioxide per person per year.

    Growing produce on floating rafts as a response to rising sea levels

    Floating farms are an important tool for farmers in Bangladesh, as they enable them to grow food year round. They also provide an additional source of physical and financial sustenance during floods. This means that they can continue to provide food for their families in an area where conventional farming is unprofitable.

    The Bangladesh government is reviving this traditional form of farming as a means of reducing climate change vulnerability. Floating farms are also considered a community initiative because they allow people to grow food during a time when flooding is prevalent.

    The United Nations Food and Agricultural Organization (UN FAO) considers these floating gardens to be globally important agricultural heritage systems. Floating rafts provide farmers with a secure platform for planting vegetable and fruit seedlings.

    The Pirojpur district in southwestern Bangladesh is an example of a community that has depended on these floating gardens for generations. Farmers in the area have turned their agricultural land into a floating garden, planting fruit and vegetables on rafts made from water hyacinth stalks. This method of farming is called baira in Bangladesh.

    Currently, 6,000 subsistence growers are already using these rafts to grow vegetables. According to agricultural experts, these rafts are adaptable to floods and can provide a more reliable method of growing crops.

    The Bangladesh government recently included an expansion of floating agriculture in its climate change adaptation strategy. In addition, various NGOs have established floating agriculture projects in Bangladesh.

    Researchers at the University of Ohio are also exploring the possibility of other countries turning to rafts in response to rising sea levels. They believe that it could be a crucial technique for local families to rely on in the future.
