Conservation groups welcome the canceled leases in the Arctic National Wildlife Refuge but fear more could be on the way

The sea-ice surrounding Antarctica is well below any previous recorded winter level, satellite data shows, a worrying new benchmark for a region that once seemed resistant to global warming.

An international team of scientists has successfully conducted large-scale helicopter-based observations along the coast of East Antarctica and has identified pathways through which warm ocean water flows from the open ocean into ice shelf cavities for the first time.

CNN - The Biden administration announced Wednesday it will cancel seven Trump-era oil and gas leases in the Arctic National Wildlife Refuge and protect more than 13 million acres in the federal National Petroleum Reserve in Alaska, stymieing a years-long attempt to drill in the protected region.

The environment Inuit have lived in for millennia is changing fast. Canada’s government once ignored Indigenous knowledge of it but now they are jointly creating the Nunatsiavut conservation area

KODIAK, Alaska – U.S. Coast Guard Cutter Healy (WAGB 20) crew and embarked researchers departed Kodiak, Saturday, for the cutter’s second mission this year in the high latitudes of the Arctic Ocean.

Chemists race to understand how global pollutants are contaminating the Arctic as climate change threatens to intensify the problem

The ice shelves—the marine-terminating glaciers of the Antarctic Ice Sheet—are melting, and it's not just because of rising atmospheric temperatures. In a one-two punch, ice shelves in Antarctica are fighting a losing battle against rising temperatures both at the surface and under their body.

Scientists aboard a research vessel near Antarctica pulled their nets out of the chilly ocean water. Among their catch, they found a 20-armed creature with a distinctive body shape. It’s a new species.

There is a danger Antarctica "stops acting as a refrigerant for the planet, and it starts acting as a radiator", one of the scientists involved has warned.

Aug. 6—For Bobby Schaeffer, observing the weather in Kotzebue is a crucial daily task. In the continuously changing Arctic, the ocean freezes later in recent years, exposing coastal communities to storms. And the warming waters affect seals and birds that locals rely on for subsistence.

A subpolar species associated with Atlantic water expanded far into the Arctic Ocean during the Last Interglacial, analysis of microfossil content of sediment cores reveals. This implies that summers in the Arctic were ice free during this period. The findings are published in Nature Geoscience.

Trying to explain what’s behind the vanishing sea ice and extreme marine heat has prompted lively discussion in the scientific community.

Amid a summer of record heat, the most dramatic impact may be taking place under the cover of Antarctic night.

The precipitation in West Antarctica, especially around the Antarctic Peninsula, exhibits large variability on the interannual time scale. In recent years, scientific research activities, tourism and fisheries have been experiencing remarkable growth there. Thus, understanding the variability of precipitation in West Antarctica, including the Antarctic Peninsula, is of substantial importance both for scientific and practical aspects.

About 400,000 years ago, large parts of Greenland were ice-free. Scrubby tundra basked in the sun's rays on the island's northwest highlands. Evidence suggests that a forest of spruce trees, buzzing with insects, covered the southern part of Greenland.

Science and technology portrayed during undersecretary’s Alaska visit as essential to meeting challenges of public safety and emergency response

The cruise ship with about 1,000 passengers anchored off Nome, too big to squeeze into into the tundra city’s tiny port. Its well-heeled tourists had to shimmy into small boats for another ride to shore.
