Drilling the Seabed Below Earth’s Most Powerful Ocean Current
Starting this month, scientists aim to study the Antarctic Circumpolar Current’s past dynamics by drilling into the seabed in some of the planet’s remotest marine regions.

Scientists See Fingerprint of Warming Climate on Droughts Going Back to 1900
In an unusual new study, scientists say they have detected a growing fingerprint of human-driven global warming on global drought conditions starting as far back as 1900.

Drought: A Wide-Angle Picture
A new book, the second in a series of primers with the Earth Institute imprint, provides an interdisciplinary overview drought, bringing together many fields including climate science, hydrology and ecology.

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.

Hurricane Maria Study Warns: Climate-Driven Storms May Raze Many Tropical Forests
Biodiversity could suffer as result, and more carbon could be added to the atmosphere.
