While Antarctica has not lost as much sea ice as the Arctic, as global warming progresses, the continent has been losing its ice at a faster rate. In a surprising new study, scientists from The Pennsylvania State University (Penn State) found that sea ice loss in Antarctica causes an increased amount of snowfall over its […]
Quick Key Facts What Is Arctic Sea Ice? Sea ice forms and covers most of the Arctic Ocean during the shorter, darker winter months. How much of the ocean’s surface is covered in sea ice is an important indicator of climate change. By mid-September, after the summer melt, the area covered by Arctic sea ice […]
Even with dramatic shifts in emissions, summer sea ice in the Arctic is doomed. A new analysis has found that even greatly and swiftly reducing greenhouse gas emissions will not prevent the disappearance of sea ice in September over the coming decades. Researchers predict the first summer without Arctic sea ice will happen in 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 […]
