"Rapidly melting Antarctic ice is dramatically slowing down the flow of water through the world's oceans, and could have a disastrous impact on global climate, the marine food chain and even the stability of ice shelves, new research has found."

"Arctic sea ice declined dramatically in 2007 and has never recovered. New research suggests the loss was a fundamental change unlikely to be reversed this century, if ever — perhaps proof of the sort of climate tipping point that scientists have warned the planet could pass as it warms."

"Sea ice in Antarctica shrank to the smallest area on record in February for the second year in a row, continuing a decade-long decline, the European Union's climate monitoring service said Tuesday."

"Environmental campaigner Greta Thunberg and dozens of other activists on Monday blocked entrances to Norway's energy ministry, protesting against wind turbines built on land traditionally used by indigenous Sami reindeer herders."

"The Australian government plans to make an area about the size of Germany in the Southern Ocean a marine zone, strengthening protections around Macquarie Island for millions of penguins and seals."

"The amount of floating sea ice encircling Antarctica reached the lowest level ever recorded, scientists reported Tuesday, a sign that one of the most remote and mysterious facets of the climate system may, at last, be responding to the overall planetary warming trend."

"With the Ukraine war, international collaborations with Russia on Arctic research and governance have been strained or broken off. This loss of critical cooperation is compromising efforts to confront mounting environmental risks in the Arctic, from shrinking sea ice to pollution."

"A sharp spike in Greenland temperatures since 1995 showed the giant northern island 2.7 degrees (1.5 degrees Celsius) hotter than its 20th-century average, the warmest in more than 1,000 years, according to new ice core data."

"Emperor penguins and reindeer were among the species highlighted in a World Wildlife Fund (WWF) report as severely threatened by  the cascading impacts of climate change."
