Why Are Siberian Temperatures Plummeting While the Arctic Warms?
The answer involves the intricacies of stratospheric circulation, which, if better represented in climate models, could help predict extreme weather events in Siberia and elsewhere.
Heat Waves, More Than Coral Death, May Cause Fish to Flee Reefs
A study over a broad swath of the Great Barrier Reef shows that warming waters directly cause fish and invertebrates to leave the reef, making it harder for coral to recover from bleaching events.
Youth Urge Action on Climate Change and Environmental Justice
Marches on Saturday in Washington, D. C., and other cities spring from “a sliver of hope left” to act against climate change.
Glacial Meltwater Plumes Support Greenland Phytoplankton Blooms
Field measurements from the Bowdoin Glacier show that entrainment of deep water into upwelling glacial discharge delivers crucial nutrients to the surface of the surrounding fjord.
