Sea ice plays many important roles for the global climate: Its white surface can reflect energy back into space, helping the planet cool. It also acts like a blanket for the ocean, insulating it ...

Each year, the sea ice would spread down from the Arctic and across the Bering Sea Shelf, often enveloping St. Paul in a sheet of white. The island’s interplay with this ice and the cold, salty ...

Last month’s record low for the global sea ice extent came on what Copernicus said was the third warmest February globally. The agency said it marked the 19th month out of the past 20 in which ...

The disappearance of sea ice in polar regions due to global warming not only increases the amount of light entering the ocean, but also changes its color. These changes have far-reaching ...

A Real Ice trial pumping seawater over the ice in Cambridge Bay, Canada, on 23 January 2024. The aim is to thicken and restore disappearing Arctic sea ice.

As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research.

A walrus mother and calf rest on an ice floe in Alaska’s Chukchi Sea in 2010. Other resting walruses are in the background. Sea ice extent is tracked by the National Snow and Ice Data Center, a ...

Melting Antarctic ice contributes to global sea-level rise, so a reversal of melting will slow that down. Understanding the dynamics of ice mass on Antarctica is thus essential.

According to the study, the massive Pine Island Ice Shelf is in danger of collapsing. If it does, it could raise sea levels by 1.6 feet. The threat and terrifying effects of climate change have ...
