Solar radiation enters the Earth's atmosphere without any hindrance and should normally leave it as heat. Unfortunately, this is impeded by the thickening "greenhouse roof" consisting of carbon dioxide and other gases.

In the search for life elsewhere in the universe, scientists have traditionally looked for planets with liquid water at their surface. But, rather than flowing as oceans and rivers, much of a planet's water can be locked ...

A pair of Earth scientists, one with the University of Calgary, in Canada, the other from the University of Cambridge in the U.K., has found that studying rocks found in Duluth, Minnesota, might help us understand how Mars ...
Geologists are interested in the sedimentary cycle—erosion from mountains that forms sand that is carried out to the ocean—because it's foundational for understanding how the planet works.

Chemically, carbon dioxide is incredibly simple—it is just one carbon atom linked with two oxygen atoms. Together they create a colorless gas that makes up just a tiny fraction of the Earth's atmosphere, about 0.04%.

A new study shows that global atmospheric dust—microscopic airborne particles from desert dust storms—has a slight overall cooling effect on the planet that has hidden the full amount of warming caused by greenhouse gases.
