As Oceans Warm, Microbes Could Pump More CO2 Back Into Air, Study Warns
A new study suggests bacteria may respire more carbon dioxide from the shallow oceans to the air as seas warm, reducing the deep oceans’ ability to store carbon.

Warm Autumn Winds Could Strain Antarctica’s Larsen C Ice Shelf
New research shows that the Larsen C ice shelf—the fourth largest ice shelf in Antarctica—experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017.

Carbon Lurking in Deep Ocean Threw Ancient Climate Switch, Say Researchers
A million years ago, a longtime pattern of alternating glaciations and warm periods dramatically changed, when ice ages suddenly became longer and more intense. Scientists have long suspected that this was connected to the slowdown of a key Atlantic Ocean current system that today once again is slowing. A new study of sediments from the…

Deep-Sea Drillers Investigate Shedding of Antarctic Icebergs
Scientists are sailing to remote areas of the Southern Ocean to drill cores from the bottom that they hope will contain clues to past rapid changes in the Antarctic ice, and how it may react to warming climate today.
