A new study led by Columbia scientists suggests that climate change could soon eliminate an atmospheric barrier that protects much of the U.S. East Coast from powerful hurricanes.

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.

Years before Alex Halliday joined Columbia University’s Earth Institute as its director, he was changing the field of geochemistry. Halliday was recognized in the Queen’s New Year’s Honours 2019 for his pioneering research.

In an unusual new study, Columbia scientists say they have detected a growing fingerprint of human-driven global warming on drought conditions across the world starting as far back as 1900.

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