New University of Washington-led research attributes accelerated warming to reduced cloud reflectivity. As efforts to improve air quality have reduced pollution, clouds became less mirror-like, letting more solar radiation reach Earth and revealing the true impact of greenhouse gases.
The Atlantic Meridional Overturning Circulation, or AMOC, is a system of ocean currents that plays a crucial role in regulating Earth’s climate by transporting heat from the Southern to Northern Hemisphere. Climate models have long predicted that global warming will cause the AMOC to weaken, with some projecting what amounts to a near-collapse relative to the AMOC strength in observations today. But a new study from a team of researchers that included the University of Washington shows that the AMOC is likely to weaken to a much lesser extent than current projections suggest.
How fast the level of atmospheric carbon dioxide — and with it, the temperature — goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too. Camille Hankel, a postdoctoral researcher at the Cooperative Institute for Climate, Ocean and Ecosystem Studies, talks about her research on the Atlantic Ocean circulation.
Around Anchorage, communications among the critically endangered population of Cook Inlet beluga whales may be masked by ship noise in their core critical habitat, accordingly to the first repertoire of their calls.
Five University of Washington experts comment on the current El Niño, its effect on Pacific Northwest winter weather, as well as on regional and global ocean temperature trends.
