Walker is the chairwoman of the Northern Chumash Tribal Council, a small group of Indigenous Americans who once lived along the coast of San Luis Obispo county. Records of their occupation of the central coast date back to 18,000 years. Continue reading...

After eventful and busy months, the Arctic season ends this weekend with the Polarstern expedition called ArcWatch-1. The team of almost 100 crew and scientists measured sea ice thickness and properties, recorded the currents and chemical properties of the ocean and investigated life in and under the ice, in the open water and at the bottom of the deep sea. Their data show significant changes compared to previous expeditions. On 7 September 2023, Polarstern reached the North Pole, and on 20 September there was the world's first livestream of an ROV under-ice dive from the Central Arctic.

The annual Arctic sea ice minimum (lowest) annual extent was the sixth-lowest on record this year, while Antarctic sea ice reached its lowest maximum ever. These both continue a long-term downward trend due to human-caused global warming.
Arctic sea ice likely reached its annual minimum extent on Sept. 19, 2023, making it the sixth-lowest year in the satellite record, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). Meanwhile, Antarctic sea ice reached its lowest maximum extent on record on Sept. 10 at a time when the ice cover should have been growing at a much faster pace during the darkest and coldest months.

Jupiter’s mysterious moon Europa may hold carbon in the ocean lurking beneath its icy shell
In the “weather kitchen,” the interplay between the Azores High and Icelandic Low has a substantial effect on how much warm water the Atlantic transports to the Arctic along the Norwegian coast. But this rhythm can be thrown off for years at a time. Experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research finally have an explanation for why: Due to unusual atmospheric pressure conditions over the North Atlantic, low-pressure areas are diverted from their usual track, which disrupts the coupling between the Azores High, the Icelandic Low and the winds off the Norwegian coast. This finding is an important step toward refining climate models and more accurately predicting the fate of Arctic sea ice in the face of progressing climate change.
