Twenty-three million years ago, the Antarctic Ice Sheet began to shrink, going from an expanse larger than today’s to one about half its modern size. Ancient fossilized leaves retrieved from a lake bed in New Zealand now show for the first time that carbon dioxide levels increased dramatically over a relatively short period of time as the ice sheet began to deteriorate.
A new white paper reviews climate impacts already underway in the Arctic, and examines further changes expected to take place even if the world meets the goals of the Paris Agreement. It will be presented today at a meeting at the White House of national-level science ministers and advisors from around the world.
This past July was Earth’s hottest month since record keeping began, but warming isn’t the only danger climate change holds in store. Recent years have seen a dramatic increase in the simultaneous occurrence of extremely cold winter days in the Eastern United States and extremely warm winter days in the Western U.S., according to a new study.
The heavy rains and flooding in Louisiana have been devastating. Can we attribute the severity of it to climate change? How you measure that depends on the questions you ask.
This week climate scientists from the United States and Europe will join with officials from government and international agencies at Columbia to share knowledge about climate change and strategies for adaptation in North America and the Caribbean.
A new study finds that the climatological phenomenon known as the North Atlantic Oscillation contributes to fluctuations in the cod population off the New England coast, and could help fishery managers protect the population from future collapse.
Twelve students from New York and New Jersey are spending July in laboratories at Lamont-Doherty Earth Observatory, working with the scientists. The internship program enables students to spend four weeks exploring what it means to be an earth scientist.
A new project combines cutting edge climate science and mobile soil labs for African farmers and service providers.
To improve climate forecasts, scientists study the complex interactions and mechanisms within the climate system. But they also need to hear from potential users of climate information, such as farmers, to get a better understanding of how people may use that information in their decision making.
International Research Institute for Climate and Society and the Mailman School of Public Health will hold a two-day meeting to talk about how climate influences issues of public health, from heat waves to infectious diseases. The event will be livestreamed, and you also can follow it on Twitter at #healthclimate2016.
