Rising temperatures are fueled, in part, by declining cloud cover — which could be a potential climate feedback loop.

Global warming is producing a rapid loss of plant species—according to estimates, roughly 600 plant species have died out ...

Alfred Wegener was one of those people. Though trained as an astronomer, he was a specialist on Greenland. He noticed that, based on nineteenth-century longitude determinations, it appeared that ...

We know that this is not the case. Wegener suggested that mountains formed when the edge of a drifting continent collided with another, causing it to crumple and fold. For example, the Himalayas ...

Scientists studied plant DNA to understand past extinctions. They found that warming climates increase competition, ...
