Research at the NASA Goddard Institute for Space Studies (GISS) emphasizes a broad study of global change, which is an interdisciplinary initiative addressing natural and man-made changes in our environment that occur on various time scales — from one-time forcings such as volcanic explosions, to seasonal and annual effects such as El Niño, and on up to the millennia of ice ages — and that affect the habitability of our planet.

The Union of Concerned Scientists puts rigorous, independent science to work to solve our planet’s most pressing problems.

EPA's purpose is to ensure that national efforts to reduce environmental risk are based on the best available scientific information. [Climate Change information is no longer available on the EPA website. The above link is to the archived information and may not be up to date.]
