    NYC’s Public-Private Partnerships to Fight Climate Change

    New York City’s Carbon Challenge is helping to foster public-private partnerships that are crucial in any city’s attempt to combat climate change.

    Almost Home, with Another 7 Million Years of Climate History

    Science at sea isn’t easy, but the benefits are huge, writes Sidney Hemming in her final post from a two-month expedition that collected millions of years of climate history in the deep-sea sediment from off southern Africa.

    Filling a Climate Gap and Helping Rwandan Farmers

    Agriculture makes up a major portion of Rwanda’s economy, and employs eight in 10 Rwandans. Of course, farmers are hugely dependent on the climate, and a new project hopes to ensure they get timely information so they can plan for both good times and bad.

  • The Damaging Effects of Black Carbon

    The Damaging Effects of Black Carbon

    Air pollution, both outdoors and indoors, causes millions of premature deaths each year. The deaths are mainly caused by the inhalation of particulate matter, especially black carbon. But black carbon not only has impacts on human health, it also affects visibility, harms ecosystems, reduces agricultural productivity and exacerbates global warming.

  • The Presidency and Sustainability

    The president’s accomplishments are particularly noteworthy given the toxic political environment he must operate within. Flint, Michigan’s water crisis provides an example of how partisan politics is dominating federal environmental policy.

    Where Will Sea-Level Rise Hurt the Most?

    A study out yesterday says that the lives of up to 13 million people in the United States may be disrupted by sea-level rise in the next century. But another study says that while much hard infrastructure like houses, piers, seawalls and roads may have to be kissed goodbye, some 70 percent of natural landforms…

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
