  • Cash for More Than Just Clunkers

    Our inability to predict policy outcomes was once again confirmed this week by the wildly popular Cash for Clunkers program.

  • Jeffrey Sachs talks about Columbia Climate Center in new video

    Something that many people wonder about climate change, especially in light of the current economic crisis, is whether we can afford to focus on the climate when there are so many other pressing global issues like the economy, terrorism, and major public health crises. Part of our mission here at the Columbia Climate Center is…

  • Sachs at Haverford College on Global Economic Crisis

    A slot machine turning up three lemons is how Jeffrey Sachs described the global economic crisis at Haverford College last week.  “Three ‘uns’: It is unstable, unfair, and unsustainable,” he said. “It’s the life-and-death struggle of the poor, and the plight of the planet.” “You are the answers,” he told the audience. “This crisis is…

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
