    Mozambique Core Brings Up 7 Million Years of Climate History

    With calm seas, the JOIDES Resolution’s latest sediment core comes up with what appears to be a fantastic, cyclic climate signal that is continuous back 7 million years, writes Sidney Hemming.

  • Pump Meltwater Back on Antarctica? Do You Have 850,000 Wind Turbines?

    Pump Meltwater Back on Antarctica? Do You Have 850,000 Wind Turbines?

    A new study that looked at the feasibility of lowering sea levels by pumping water onto icy Antarctica offers a warning about the costs today’s greenhouse gas emissions may be creating for future generations.

    Scientists Prepare ‘Climate City’ for Take-Off

    Sometime soon, a flock of “Climate Birds” could be ascending from a former NATO base in northeast France to take the measure of climate change around the world.

    We’re Headed for Mozambique!

    After weeks of anticipation, permission arrived just in time to core off Mozambique. Sidney Hemming and her team of scientists aboard the JOIDES Resolution are excited about what they might learn from the ocean sediment.

    MESSENGER Data Reveal Evidence of Ancient Carbon-Rich Crust on Mercury

    Mercury’s dark surface is revealing intriguing new clues about the formation of the solar system, including evidence announced today that the planet closest to the Sun may have formed in part from carbon, a key component of life.

    Bleach Patrol: Turning Surfers into Scientists to Help Coral Reefs

    With coral bleaching spreading, a new project and app called Bleach Patrol is putting surfers, divers and snorkelers to work as citizen scientists, keeping an eye on the world’s coral reefs.

    In a Vast Ocean, Studying Impact of the Tiniest Creatures

    Vast portions of the oceans contain low levels of the nutrients that normally sustain life. Yet these areas are not devoid of life. Once thought to be biological deserts, recent research has shown that such nutrient-poor marine systems could significantly contribute to the amount of carbon dioxide that is trapped into the deep ocean, influencing…

  • Syria’s Drought Likely Its Most Severe in More than 900 Years

    Syria’s Drought Likely Its Most Severe in More than 900 Years

    “If climate change is having an impact and is making droughts worse, then we should see this in the record over several centuries—and we do,” said the study’s author, Benjamin Cook.

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
