The federal government requires diesel emissions to meet certain air quality standards, known as NAAQS, set in the 1970 Clean Air Act. If your area is not an “attainment area,” the concentration of pollutants in the air must be below these limits. In order to meet these standards, you’ll need to create a state implementation […]

Earth’s climate system responds to small changes in the orbit of the sun and its rotation. Small variations in the Earth’s rotation and latitudinal solar energy distribution initiated ice-age cycles, which triggered changes in CO2 concentrations. During warm periods, the ice sheets melted and reflected less sunlight to space, releasing major greenhouse gases into the […]

Diversity is the variation in the number of species, in both number and identity, across space and time. It is one of the primary criteria used to evaluate the health of ecosystems and assess the value of a region or species. To better understand biodiversity, learn how it’s measured and how to use the term […]

The concept of ecosystem multifunctionality has been used to link biodiversity with ecosystem stability. It can help transform the way people view the effects of biodiversity on ecosystem stability, thereby enabling us to translate the science into policy-relevant information. One example of how biodiversity confers stability is by improving ecosystem resilience to environmental change. In […]
