  • Trials & Tribulations of Coring the Agulhas Plateau

    Trials & Tribulations of Coring the Agulhas Plateau

    Trying to drill sediment cores while the ship rides large ocean swells off the coast of Africa isn’t easy, but it’s paying off for science, writes Sidney Hemming.

    Helping Communities Respond to Climate Change

    A new tool helps scientists communicate better with communities on global climate change issues, increasing awareness and stakeholder engagement.

    Exploring Ocean Turbulence: 2016 Sloan Fellow Ryan Abernathey

    When you examine the behavior of the global oceans closely—really closely, at scales smaller than 100 kilometers—eddies and jets and fronts start to appear. For Ryan Abernathey, this is where ocean physics gets interesting.

  • A New Tool for Coastal Planners Preparing for Sea Level Rise

    A New Tool for Coastal Planners Preparing for Sea Level Rise

    Globally, the tool estimates at least 11 inches of sea level rise this century with ambitious efforts to lower greenhouse gas emissions and as much as 52 inches if greenhouse gas emissions continue to grow unchecked.

  • Sailing into a Storm as We Head for the Agulhas Plateau

    Sailing into a Storm as We Head for the Agulhas Plateau

    The team aboard the JOIDES Resolution just finished at their first coring site off southern Africa. The first results? “Awesome.” Sidney Hemming describes the process in words and photos.

  • Federal Environmental Policy Can’t Find the 21st Century

    The issue comes down to willingness to pay upfront for improved systems, rather than pay to address environmental emergencies later on, when pieces of the system fall apart. Both water and energy systems carry user charges, but weak, ideologically-bound politicians refuse to allow these fees to grow to pay the capital cost of modern infrastructure.

  • 6 Million Years of Sediment, Studded with Tiny Fossils

    6 Million Years of Sediment, Studded with Tiny Fossils

    Sidney Hemming and her team have started examining their first sediment core from off southern Africa. It appears to contain about 6 million years of history.

    Court Ruling on Clean Power Plan a Setback, But…

    The Supreme Court’s decision Tuesday to postpone implementation of the Clean Power Plan represents a setback for efforts to combat climate change; but the damage to the U.S. ability to meet pledges it made at the Paris climate summit in December “is less than it might seem,” says Michael Gerrard.

  • Climate Change Isn’t Just a 21st Century Problem

    Climate Change Isn’t Just a 21st Century Problem

    Humans have been burning fossil fuels for only about 150 years, yet that has started a cascade of profound changes that at their current pace will still be felt 10,000 years from now, a new study shows.

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
