The Evidence
Oceans are rising, Antarctica is losing its ice sheets, and the lower atmosphere is heating up. Satellite data (bottom) shows the atmosphere is warming at its lowest layer (the troposphere), while the stratosphere, which begins around 10 kilometers above the ground, is cooling. Scientists say this is consistent with the greenhouse effect.
