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

New research digs into the history of sea-level rise and confirms that modern changes do result from human activity.

Ice sheets in Greenland and Antarctica have lost 318 gigatons of ice a year for 16 years. Just one gigaton would fill 400,000 Olympic-sized swimming pools.

The huge machine keeps ice at the right temperature to examine how melting glaciers slide. It led to a new "slip law" to benefit future research.

As the climate warms, the Gulf Coast will become even more susceptible to extreme storm surges, research finds. That's especially true for New Orleans.

Researchers used robotic kayaks to track meltwater and discovered that massive tidewater glaciers may be melting a lot faster than anyone thought.

Greenland is losing ice mass seven times faster than it did in the 1990s. "…we're in the worst-case scenario," says one researcher.

Researchers argue that new computer models are the best way to predict how current policies will affect migration in the face of rising sea levels.

Newly digitized archival film footage suggests that the Thwaites Glacier ice shelf in Antarctica could collapse sooner than expected
