Recent satellite data from the U.S. National Snow and Ice Data Center shows that Antarctic sea ice extent is far below any level ever recorded. The continent’s sea ice is an important regulator of Earth’s temperature by not only lowering the temperature of the water below, but also reflecting the sun’s rays back into the […]
Evidence from the last ice age has troubling implications for future sea level rise. The research, published in Nature Wednesday, found that ice sheets could collapse around 20 times faster than previously assumed as the climate warms. “Our research provides a warning from the past about the speeds that ice sheets are physically capable of […]
The Arctic sea ice extent for the Northern Hemisphere winter of 2023 is the fifth lowest on record. The National Snow and Ice Data Center (NSIDC) announced Wednesday that the Arctic sea ice likely reached its maximum extent on March 6 at 5.64 million square miles. That’s 398,000 square miles below the average maximum for […]
Sea ice forms in the Arctic and Antarctic in winter and retreats in summer, but it doesn’t disappear completely — at least not yet. The floating frozen seawater has a surprisingly strong influence on weather patterns and ocean circulation in the polar regions and beyond. Rapidly shrinking Arctic sea ice has been one of the […]
By Jonathan Bamber The Earth is approximately 1.1℃ warmer than it was at the start of the industrial revolution. That warming has not been uniform, with some regions warming at a far greater pace. One such region is the Arctic. A new study shows that the Arctic has warmed nearly four times faster than the […]
Few animals represent the face of the Arctic like polar bears. The largest bears in the world, polar bears are excellent swimmers who spend more time in the sea than they do on land. Sea ice is the platform from which they hunt the seals needed to obtain the necessary calories to survive.
The Center for Biological Diversity filed a notice of intent this week to sue the U.S. Department of the Interior and Bureau of Land Management (BLM) for allegedly failing to adequately protect polar bears from a Western Arctic exploration project. Under the Endangered Species Act, a notice of intent is required 60 days before the […]
By Kenny Stancil Over the past five decades, the Arctic has warmed three times faster than the world as a whole, leading to rapid and widespread melting of ice and other far-reaching consequences that are important not only to local communities and ecosystems but to the fate of life on planet Earth. The Arctic Monitoring […]
The sea ice cover in Canada’s Gulf of St. Lawrence is the lowest it has ever been since measurements began, and that is seriously bad news for the harp seals that are typically born on the ice. A cold-water mammal, harp seals rarely spend any time on land, National Geographic explained. Instead, they feed in […]
