The “Wet-Gets-Wetter” Response to Climate Change Does Not Always Apply
While the precipitation response to a warming climate is often stated as the “wet gets wetter,” this response does not apply to east-west overturning circulations like the Pacific Walker circulation.

Antarctic Ice Sheet Has Lost a Connecticut-Sized Amount of Ice Over the Past 30 Years
A new study of Antarctica has found that since 1996, its ice sheet has lost 12,820 square kilometers (nearly 5,000 square miles) of ice—nearly enough to cover the state of Connecticut, or 10 cities the size of Greater Los Angeles.

Why More Rain Doesn’t Mean More Erosion in Mountains
Erosion in mountain-basin systems driven by long-period climate variations is buffered by an erosion saturation effect, which weakens peak erosion and leads to reduced sediment flux.
