    Preparing for Climate-Related Food Shocks

    Researchers are investigating if the projected increase in climate change-generated droughts, floods, heat waves and other intense short-term occurrences will result in increased shocks that could jeopardize food security worldwide.

  • An Ecological Traffic Jam in the Warming Tropics?

    An Ecological Traffic Jam in the Warming Tropics?

    The tropics are already hot, and they’re getting hotter as global temperatures rise. A new study offers a glimpse into how seriously a couple more degrees could disrupt the region’s ecological map.

  • Greenland Set Melt Records in 2015 Consistent with ‘Arctic Amplification’

    Jet Stream Reached Northern Latitudes Never Before Recorded

  • New Support For Human Evolution In Grasslands

    A 24 Million-Year Record of African Plants Plumbs Deep Past

  • The Connection Between Climate and Public Health

    The Connection Between Climate and Public Health

    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.

    Trump vs. Clinton: What the Election Could Mean for Climate Policy

    The outcome of this year’s presidential election could have far-reaching implications for the fate of our planet because the two presumptive candidates, Democrat Hillary Clinton and Republican Donald Trump, have very different ideas about climate change. What will they do about the Paris accord and climate change?

    Iron Fertilization Won’t Work in Equatorial Pacific, Study Suggests

    Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no effect.

    The 2 Million Year Melee: Neanderthals vs. Humans

    Given their adaptation to cold climes and their advanced, albeit under-appreciated, skills, how were Neanderthals beaten out by their human counterparts? The answer lies in a combination of culture and genetics that enabled the successful radiation of humans.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
