"Vital Arctic sea ice shrank to tie its lowest measured level for the winter, the season when ice grows, as a warming Earth shattered records across the continents."

"Over the past two summers, a pair of remote and treeless volcanic islands in the eastern Bering Sea broadcast signals of climate change danger in the marine ecosystem that feeds Alaska residents and supports much of the state’s economy."

"Ice loss in the Antarctic Ocean may be killing the sea birds during their molting season."

"The increase in marine Arctic traffic, which received increased attention as U.S. President Donald Trump pushed for the United States to take over Greenland, has come with a heavy environmental cost: black carbon, or soot, that spews from ships and makes the ice melt even faster. "

"Scientists say increasing shipping traffic is interfering with the whales’ ability to hunt and communicate. To protect the animals, conservation groups are urging the International Maritime Organization to instate mandatory measures to reduce underwater noise."

"Warming temperatures are forcing Antarctic penguins to breed earlier and that’s a big problem for two of the cute tuxedoed species that face extinction by the end of the century, a study said."

"What happens in Greenland doesn’t stay in Greenland. Turns out, the fate of the world’s largest island has outsize importance for billions of people on the planet. That’s because of the one thing that Greenland is quickly losing: ice."

"After a 12-day crossing, and a hard slog through sea ice, the field work on this Antarctic expedition is ready to start."

"After a 12-day journey across the southern seas, the nearly 40 scientists aboard the icebreaker Araon on Wednesday reached Antarctica’s fastest-melting glacier, the Thwaites. An ambitious campaign to study the ice by air, under sea and with boots on the frozen surface is now underway.

"Scientists said the loss hinders their work and diminishes America’s leading presence on the continent. The NSF said it continues to support Antarctic research."

"Mining company Blue Moon Metals plans to dispose of its mining waste in Repparfjord, a nationally protected salmon fjord in the Norwegian Arctic that Indigenous Sámi fishers rely on."
