    Finding Answers to the Worsening Water Crisis in Gujarat, India

    As explained in a recent blog post, falling groundwater levels in the Northern regions of the state of Gujarat, India, are reaching dramatically dangerous proportions.  Columbia Water Center (CWC), however, believes that there are numerous technologies and practices that could save significant amounts of water and energy.  Farmers have shown interest in applying them, but…

    The Red Queen and The Evolution of Sex

    In the biological world, both within and between species, adaptive progress and success are relative. This notion of evolutionary relativism is known as the Red Queen Effect, a term derived from the Red Queen’s race in Through the Looking-Glass by Lewis Caroll.

    Setting up camp 184 miles from the South Pole

    Our field team flies from McMurdo to their first base camp, named CTAM, which stands for Central Transantarctic Mountains. This camp is set up by the US National Science Foundation every 5 to 10 years, with input from scientists on the cutting edge research that can be done in the region.

    Michigan Case Demonstrates Growing Importance of Courts for Water Issues

    According to a recent report by Deutsche Bank, the number of US lawsuits related directly or indirectly to climate change rose by nearly 300% between 2009 and 2010. In addition to cases focused more broadly on climate change, there have also been a growing number of cases focused specifically on water regulations. Examples of the…

    Our Oceans: A Plastic Soup

    “Humanity’s plastic footprint is probably more dangerous than its carbon footprint,” said Captain Charles Moore, who, in 1997, discovered the Great Pacific Garbage Patch. Its name is misleading because the huge expanse of floating marine debris is actually more like a soup of confetti-sized plastic bits, produced by the runoff of our throwaway lifestyle that…

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
