Climate scientists at a meeting of the American Association for the Advancement of Science this week were elated to hear that the United States and five other countries had agreed to work toward cutting pollutants other than carbon dioxide thought to cause about a third of current human-influenced global warming. After all, many of them [...]
Increased growing-season heat due to climate change in coming decades could push staple U.S. crops off a cliff, and cause world food prices to jump, a Columbia University economist told a press briefing at a top scientific meeting this week. In a panel organized by the American Association for the Advancement of Science, economist Wolfram [...]
With 7 billion people on the planet and some 40 percent of earth’s land surface already covered with croplands and pastures, the only remaining frontiers for agricultural expansion are dwindling tropical forests. Some see high-yield industrial-scale farming as a way to take the pressure off; the theory goes that if more produce can be grown [...]

Scientists often invoke climate as a possible factor in human evolution; but only recently have they developed the ability to get enough information about past climates and related fossil evidence to see any details. A half-dozen leading paleontologists and climate scientists discussed recent advances in a symposium this week at the annual meeting of the [...]
Since 2005, the Educational Global Climate Modeling Project has been downloaded 50,000 times, and adopted for teaching and research at hundreds of universities and other institutions.
[Last updated: Dec. 13, 2012] Journalists may join Earth Institute research field expeditions, which take place on every continent and every ocean. Below: selected projects, in rough chronological order. (Work in and around New York listed separately at bottom.) While in the field, researchers may be available by phone or email, depending on site. Some expeditions [...]
Scientists at Columbia University’s Earth Institute will present important new work on global climate, air pollution, agriculture and other issues at the Feb. 16-20 meeting of the American Association for the Advancement of Science, in Vancouver, B.C. Click hyperlinks for scientist contacts and other information. Background materials will be posted just before the meeting at [...]
Floods, volcanoes, earthquakes–really, very little good news comes out of this sort of thing. Maybe the occasional feel-good story about, say, a child miraculously dug from the rubble days later, tired but unharmed and in good spirits, having survived on a cache of crackers and Coke. Actually, says John Mutter, an Earth Institute professor of sustainability studies, disasters can sometimes [...]
An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period analogous to scenarios for climate change in coming decades. With nations in the volatile region already running short on water, the finding could be a [...]
An innovative crop insurance program that protects small African farmers against extreme weather made its first payouts last week, to growers in northern Ethiopia. The pilot “microinsurance” program gave a total of $17,392 to 1,800 farmers in seven villages, following a drought earlier this year. The HARITA (Horn of Africa Risk Transfer for Adaptation) pilot was [...]
