    Yes, We Can Afford to Remove Carbon from Air

    Recently, the American Physical Society (APS) released a report on the direct capture of carbon dioxide from air. The report concludes that air capture could be a powerful tool for mopping up carbon dioxide emissions that otherwise would escape to the air, for providing carbon dioxide for synthetic liquid fuels in the transportation sector, and…

    Squeezing the Last Drops out of Sicily

    If you were to drive south from Palermo, Sicily toward Monreale, you would be ringed in by green mountains, the sparkling white of ancient and modern buildings and the azure Mediterranean Sea receding behind you. Continuing south through the island’s mountainous interior, you would pass verdant agricultural fields on your way past Corleone, the namesake…

    Water-Saving Project in Punjab, India Reaches Out to Farmers Through Cooperatives

    After working with over 500 farmers last year to conduct a field experiment on the use of tensiometers to reduce irrigation in rice fields, this year they will be working with about 5,000. As part of this expansion, our program partners at the Punjab Agricultural University (PAU) are working with Cooperative Societies, a network of…

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
