Understanding past sea level change is necessary for predicting future sea level rise. The main contributors to sea level variability are ice sheet change, ocean water temperature change (e.g., ...

The Antarctic ice sheet is melting in a new, worrying way that scientific models used to project future sea level rise have not taken into account, suggesting current projections could be ...

One of the biggest challenges in predicting Antarctica’s deeply uncertain future is understanding exactly what’s driving its ice loss. A vast network of lakes and streams lies beneath the thick ice ...

Greenland has melted before, and as the climate warms, it will melt again — this time leading to what scientists warn could be 20 to 25 feet of sea-level rise. During one of the warm periods within ...

Satellite data reveals sea-level rise has unfolded almost exactly as predicted by 1990s climate models, with one key underestimation: melting ice sheets. Researchers stress the importance of refining ...

When polar ice sheets melt, the effects ripple across the world. The melting ice raises average global sea level, alters ocean currents and affects temperatures in places far from the poles. But ...

A recently discovered ice core taken from beneath Greenland’s ice sheet decades ago has revealed that a large part of the country was ice-free around 400,000 years ago, when temperatures were similar ...

The island is shedding 20 percent more than previously estimated, a study found, potentially threatening ocean currents that help to regulate global temperatures. By Delger Erdenesanaa Greenland’s ...
