A new white paper explores how advances in climate science can inform near-term investments in the global economy.
If a serious cyclone were to strike Mumbai, the results could be catastrophic, says a study underway by Lamont-Doherty Earth Observatory’s Initiative on Extreme Weather and Climate.
Billy D’Andrea’s research on the experiences of the Vikings may provide a kind of object lesson on how changing climate can affect civilizations.
The better climate models become, the harder it is to use them. A team of Columbia scientists and their colleagues are working to fix that.
Hoaxes have been calling Irma a Category 6 hurricane, but there’s no such thing. Could there be, in the future?
Over the past day and a half, Hurricane Harvey’s winds have quickened from about 35 to 109 miles per hour. What’s driving this massive power-up?
A new study found that the northeastern U.S. is at particular risk for physical and economic effects of climate hazards.
It’s not unusual for ice shelves to calve, many in the climate community fear that the breaking of Larsen C may be a signal of other events to come.
The Center has awarded nearly $1 million to four scientists whose research will improve understanding of how climate change impacts the essentials of human sustainability.
Once scientists could only observe Earth from above by using manned aircraft or satellites. Today they’re using drones to expand their research as never before.
Last winter, reporters from The New York Times joined Lamont scientists as they flew their mission of discovery over Antarctica.
