    Climate change may be affecting the jet stream

    A new study provides evidence that climate change may be affecting the northern hemisphere jet stream, which appears to be moving north and slowing down. The slowing of the jet stream could cause weather patterns to remain in place for longer, resulting in prolonged heat waves or cold snaps.

    One Planet, Too Many People?

    Can we manage the needs of 9 billion people for water, food and energy without depleting our resources and ruining the environment? “The solutions,” says Tim Fox, “are all within the capability of existing technology.”

    What Really Sways Public Opinion on Climate Change

    Being part of the Columbia Climate Center, which endeavors to improve public understanding of climate change as part of its mission, I was dismayed, but not surprised to read a study confirming that dissemination of scientific information on climate change to the public has a minimal effect on public opinion.  A recent analysis shows that…

    Ocean Acidification: Geologic Record Adds New Warning

    A new study in Science finds that the oceans may be acidifying faster today from industrial emissions than they did during four major extinctions in the last 300 million years when carbon levels spiked naturally.

    What does a glacier about to spawn an iceberg the size of New York City look like? A new animation from NASA flies you through the 19-mile crack that is slowly tearing Antarctica’s Pine Island Glacier apart.

  • EPA’s greenhouse gas rule poses challenges for US policy review process

    Just in case anyone you missed it, the US Environmental Protection Agency (EPA) is moving, albeit almost imperceptibly, toward regulating greenhouse gas (GHG) emissions. It took one more step in January, published the emissions of 6700 facilities with annual emissions of more than 25,000 MtCO2e. This category of emitters was required to report these figures…

    Climate News Roundup: Week of 2/19

    Climate change increased likelihood of Russian 2010 heatwave, The Guardian, Feb 21 The extreme Russian heatwave of 2010 was made three times more likely because of man-made climate change, according to a study led by climate scientists and number-crunched by home PC users. But the size of the event was mostly within natural limits, said…

    Climate Services: Science=Credibility

    It’s terribly important that those who provide climate services are backed up by science and most importantly, link with and understand the problems of the user community. – says John Zillman, former president of the World Meteorological Organization, in the fourth in a series of video interviews.

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
