☆ Missing a Global Climate Target Could Spell Disaster for These Polar Bears
  + stars: | 2024-06-13 | by ( Austyn Gaffney | ) www.nytimes.com   time to read: 1 min
Polar bears in the Southern Hudson Bay could go extinct as early as the 2030s because the sea ice that helps them hunt for food is thinning, a new study suggests. “We’ve known that the loss of Arctic sea ice would spell disaster for polar bears, so this might be the first subpopulation that disappears,” said Julienne Stroeve, the lead author of the study, which was published Thursday in the journal Communications Earth & Environment. Last month, the eastern half of Hudson Bay, home to the world’s most-studied polar bears, went ice free a month earlier than usual. Polar bears are used to an ice-free season of about four months when they rely on fat reserves until ice reforms and they can hunt blubber-rich seals from the floes. But the presence of sea ice doesn’t guarantee the bears will be able to hunt; it needs to be thick enough to support them.

☆ Antarctica is missing an Argentina-sized amount of sea ice – and scientists are scrambling to figure out why
  + stars: | 2023-07-30 | by ( Sophie Tanno | ) edition.cnn.com   time to read: +5 min
Antarctic sea ice has fallen to unprecedented lows for this time of year. Every year, Antarctic sea ice shrinks to its lowest levels towards the end of February, during the continent’s summer. In mid-July, Antarctica’s sea ice was 2.6 million square kilometers (1 million square miles) below the 1981 to 2010 average. While natural climate variability affects the sea ice, many scientists say climate change may be a major driver for the disappearing ice. A lack of sea ice could also have significant impacts on its wildlife, including krill on which many of the region’s whales feed, and penguins and seals that rely on sea ice for feeding and resting.
