Follow Climate & Earth ScienceNOAA Fisheries has announced new inseason actions, effective August 13, 2026, to modify landing and possession limits for commercial and recreational salmon fisheries. These changes apply to areas both north and south of Cape Falcon on the U.S. West Coast, impacting fishing operations in the region.
A study co-led by WCS and Cooper Island Arctic Research documents a significant increase in polar bear predation on black guillemots and common eiders along Alaska's Arctic coast. As sea ice shrinks, polar bears spend more time on land, leading to heightened consumption of seabird eggs and nest destruction. This development underscores climate change's destabilizing impact on Arctic ecosystems and seabird populations.
Caltech scientists have published research in Geology challenging the theory that a unique carbon-isotope signal in ancient rocks, known as the Shunga–Francevillian event, indicates a global carbon-cycle change 2 billion years ago. Their study, based on drill cores from Karelia, Russia, suggests this signal might stem from local sedimentary basin phenomena rather than a worldwide environmental shift. This re-evaluation could alter understanding of Earth's ancient climate history.
