Climate models have disagreed on the future evolution of the stratospheric polar vortex and links to the troposphere, but a new study revisits this problem with state-of-the-art climate models.
Climate Change
Tracing Anthropogenically Emitted Carbon Dioxide into the Ocean
Researchers labeled anthropogenically emitted carbon and tracked it with an ocean circulation model to determine whether it winds up in the sky or sea.
Warming and Agitation Intensify Seagrass Meadow Carbon Fluxes
Carbon dioxide emissions surge in sediments when temperature and agitation increase, both of which are likely to continue rising in degraded Mediterranean seagrass meadows.
Managing Mudslide Debris After Fires
California officials faced a conundrum in dealing with mudslides after the Thomas Fire.
Seafloor Reveals a Period of Rapid Retreat for Thwaites Glacier
New high-resolution seafloor imagery shows a series of delicate ridges produced by the glacier’s front as it bobbed daily with the tides, revealing a recent period of rapid retreat.New high-resolution seafloor imagery shows a series of delicate ridges produced by the glacier’s front as it bobbed daily with the tides, revealing a recent period of rapid retreat.
Monitoring Moisture from Afar
Undisturbed tropical rain forests are experiencing more frequent droughts, but the ecosystems are isolated and difficult to assess. Scientists are using remote sensing to expand the depth and scope of monitoring efforts.
Amazon Basin Tree Rings Hold a Record of the Region’s Rainfall
New research provides a 200-year reconstruction of interannual rainfall in the Amazon basin using oxygen isotopes preserved in tree rings in Ecuador and Bolivia.
Food Deficits in Africa Will Grow in a Warmer World
Under the combined stress of growing populations and current warming trends, many African nations will face increasing shortfalls in food production in the coming decades.
Rain Makes Skulls Bigger—in Mice
New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.
Melting Below the Pine Island Ice Shelf Minds the Gap
New research shows that increased calving from West Antarctica’s Pine Island Ice Shelf will likely drive increased circulation of warm water—and melting—below the ice.
