As the American Southwest grows hotter, the risk of severe, long-lasting megadroughts rises, passing 90 percent this century if greenhouse gas emissions continue at their current pace, a new study from scientists at Lamont-Doherty Earth Observatory says. Aggressively reducing emissions can cut that risk.
Michael Puma, an associate research scientist at the NASA Goddard Institute for Space Studies and a Center for Climate and Life Fellow, works to improve understanding of the fragility of the global food system and how it might respond to major disruptions.
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.
As global temperatures rise and heat records are broken, many wonder if New York City’s heat waves this summer were a result of climate change, and if we will experience more of them in the future.
Climate Week NYC 2016, Sept. 19 to 35, features over 70 events bringing together business, societal and government leaders to share ideas, technologies, resources and success stories that are helping to curb climate change and transition to a low-carbon society.
An expedition to the Canadian Arctic and west coast of Greenland is a moving and motivating experience for Lamont-Doherty Earth Observatory climate scientist Maureen Raymo.
As part of a generous $2 million donation to Columbia University, the Earth Institute’s Research Program on Sustainability Policy and Management will receive $700,000 to expand its research efforts on sustainability in China.
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.
Lamont-Doherty Earth Observatory scientists Ryan Abernathey and Richard Seager are investigating how processes in the ocean create extreme weather and climate conditions over land.
Lamont-Doherty Earth Observatory scientist Park Williams, recipient of a Center for Climate and Life Fellowship, is investigating the influence of climate change on droughts and wildfires.
