Temperatures in the Arctic are increasing twice as fast as in the rest of the globe, while the Antarctic is warming at a much slower rate. A new study shows that land height could be a 'game changer' when it comes to explaining why temperatures are rising…

As the oceans ebb and flow, the resulting waves and splashes form tiny bubbles.The bubbles burst and release a vapor -- called sea spray aerosol -- into the air. This aerosol scatters sunlight and is involved in forming clouds and ultimately climate. But …

By the second half of this century, rising air temperatures above the Weddell Sea could set off a self-amplifying meltwater feedback cycle under the Filchner-Ronne Ice Shelf, ultimately causing the second-largest ice shelf in the Antarctic to shrink drama…
