    Red Flags Over the Arctic’s Future

    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.

    Extreme-Weather Winters Becoming More Common in U.S., Study Shows

    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…

    As Louisiana Floods, Measuring the Climate Change Effect

    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.

    Symposium this Week on Climate and Adaptation

    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.

  • Climate and Cod

    Climate and Cod

    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.

  • A Summer of Hands-on, Minds-On Science

    A Summer of Hands-on, Minds-On Science

    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.

  • Linking Climate Forecasts, Soil Testing for Smarter Farming

    Linking Climate Forecasts, Soil Testing for Smarter Farming

    A new project combines cutting edge climate science and mobile soil labs for African farmers and service providers.

  • Science And Sustainability Management: 20 Years of Columbia’s Earth Institute

    This fall, Columbia University’s Earth Institute will mark its 20th anniversary. There were two central ideas that animated the creation of this university-wide institute. The first was to promote basic understanding of earth system science, and the second was to apply that knowledge to decisions made by governments and businesses around the world.

  • Forecasting Climate, with Help from the Baobab Tree

    Forecasting Climate, with Help from the Baobab Tree

    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.
