The American Geophysical Union fall meeting takes place Dec. 10-14 in Washington, D.C. Here is a guide to key talks and other events from Columbia’s Earth Institute.
A man from Mali explains why he spent his summer working with Columbia’s Center for International Earth Science Information Network.
A new study projects that in coming decades the effects of high humidity in many areas may surpass humans’ ability to work or, in some cases, even survive.
The International Research Institute for Climate and Society’s Alessandra Giannini was selected as one of French President’s Macron’s climate laureates.

In a remote desert region around Kenya’s Lake Turkana, paleoecologist and geochemist Kevin Uno collects fossils and sediments, searching for evidence about past climate, vegetation, animals, and water. His goal: to understand how climate affected our ancestors millions of years ago.
Ancient humans migrated out of Africa to escape a drying climate, says a new study—a finding that contradicts previous suggestions that ancient people were able to leave because a then-wet climate allowed them to cross the generally arid Horn of Africa and Middle East.
Last week, just days before Central Park’s big Ivory Crush, a Lamont-Doherty geochemist and his colleague sawed off samples of the confiscated ivory for DNA testing and radiocarbon dating. Their results could determine where and when each elephant was killed—which could help catch the poachers responsible.
