Cultures worldwide are awash with tales of great floods. What can they tell us about the reality of a wetter world?

Bacteria may add to melting on the Greenland ice sheet, which covers 656,000 square miles. If it melted, global sea level would rise an estimated 20 feet.

Salt marshes act as barriers against storm surges and natural disasters for coastal communities. But rising sea levels are breaking them down.

Climate change means more water is evaporating than is flowing in.

"Our results highlight how interconnected the Earth system is, with changes in one part of the planet driving changes in another."

A pattern among the moon, sun, and sea level could help predict sunny-day flooding, say researchers.

Charles Darwin's theory about the formation of atolls is elegant, but doesn't reflect key information: sea level. Researchers now correct his work.

Climate change will bring river avulsion, or jumping course, farther inland, predict researchers. It could mean floods in places that haven't had to worry.

If greenhouse gases continue apace, Greenland and Antarctica's shrinking ice sheets could add 15 inches to sea level rise by 2100, researchers warn.
