Some marine species are seeking out cooler waters away from the equator and toward the poles as changing global patterns are making the water too warm for them, according to a study. The researchers share their findings in this article, comparing the trend to previous events and noting that this kind of migration can have profound consequences.
A probe underneath Antarctica's Thwaites Glacier has revealed the glacier is less stable than previously believed, according to findings reported in Science Advances. An autonomous underwater vehicle gathered information about the water temperature, salinity and other data to help scientists assess the glacier's future stability.
The Rise of Aten, a significant ancient city that dates back about 3,400 years, has been uncovered near Luxor in Egypt. Researchers found skeletons and such artifacts as pottery, jewelry and tools in addition to structures.
The Pacific Northwest's Snake River is the most endangered US river this year, followed by the Lower Missouri River, Minnesota's Boundary Waters and Georgia's South River, according to a list from American Rivers. The group identified key threats facing some rivers on the list, including dams, outdated river management, excessive water-taking and pollution.
Continued climate warming could put large portions of Antarctica's ice shelves at risk of collapse, but if temperatures go up no higher than 2 more degrees Celsius, the risk of collapse would be cut in half, scientists say. A collapse would cause Antarctica's interior ice sheet to melt faster and increase sea levels, according to research published in Geophysical Research Letters.
Data available through CalEnviroScreen, California's mapping tool, can help identify areas of pollution and assist advocacy efforts. The tool could serve as a model as the Biden administration looks to update the Environmental Protection Agency's mapping tool EJScreen.
