How Dungeness crabs’ complex lifecycle will be affected by climate change
Results show that by the end of this century, lower-oxygen water on the Pacific Northwest coast will pose the biggest threat to Dungeness crabs. And while these crabs start as tiny, free-floating larvae, it’s the sharp-clawed adults that will be most vulnerable.
After California’s 3rd-largest wildfire, deer returned home while trees were ‘still smoldering’
In a rare stroke of luck, researchers from the University of Washington, the University of California, Berkeley, and the University of California, Santa Barbara, were able to track a group of black-tailed deer during and after California’s third-largest wildfire, the 2018 Mendocino Complex Fire. The megafire, which torched more than 450,000 acres in northern California, burned across half of an established study site, making it possible to record the movements and feeding patterns of deer before, during and after the fire.

Ice core data show why, despite lower sulfur emissions in U.S. and Western Europe, air pollution is dropping more slowly
Ice core data from Greenland shows why air pollution is dropping more slowly than sulfur emissions reductions. As cloud droplets become less acidic, the chemical reaction that turns sulfur dioxide into sulfate aerosol gets more efficient. The new results can improve the models that project air quality and climate change.
