  • Water is coming to Inga and Pedra Fina, Brazil

    Water Safety and Sustainability: Resilient System Design under Climate Stress The Columbia Water Center program in Ceará, Brazil, working in partnership with the Universidade Federal do Ceará, and with local and regional governments, develops appropriate drinking water infrastructure in rural communities. (Learn more in this blog piece) The following photos are from a progress report…

  • The Problem of Lawns

    In the United States, lawns are so ubiquitous that they seem to be almost a basic human right. That’s a serious problem, given the enormous resources that our North American lawn-fetish consumes.

  • Losing your glaciers? Build your own.

    Scientific American has an interesting photo piece by Gaia Vince about a place in the Himalayas that is adapting to climate change by creating its own glaciers.

  • Peak Water?

    Today, a growing number of scientists argue that global peak oil may be upon us—an argument that would seem to be supported by the increasingly heroic measures oil companies are taking (such as the ultra-deepwater drilling in the Gulf of Mexico) to keep up with global oil demand. Many underground aquifers and even some surface…

  • Your friendly neighborhood Sinkhole: a sign of things to come?

    Your old infrastructure is going to eat you alive. Well, maybe not you, exactly, but it is eating some people alive. I’m talking about the astounding sinkhole that formed in Guatemala City over the weekend.

  • Beyond Market Economics?

    Bottled water – “one of the least green and least defensible ripoffs on the market.” Is this a routine quote from one of the usual suspects of anti-bottled water campaigners? Surprisingly, no. It’s from the Economist – the journalistic bastion of free market economics – and is is included in their new special report on…

  • The Garden on the Tibibas Plain, Mali: Women’s ag. project takes off

    What follows are excerpts from a report by Severin Oman on a Women’s Community Garden project in Mali, West Africa, sponsored by the Earth Institute Millennium Village Project (MVP) and the Columbia Water Center. The project is located within the Tiby, Mali, Millennium Village cluster.

  • Communities Participate to Lower Arsenic Exposure More Effectively in Bangladesh

    There are more than 30 million people in Bangladesh at risk from arsenic contaminated water, which can cause health problems including thickening and hardening of the hands and feet, skin cancer, bladder cancer, lung cancer, vascular disease leading to gangrene, and diabetes. Columbia University scientists from the Mailman School of Public Health and Lamont-Doherty Earth…

  • The chaal and local groundwater management in India: When progress isn’t progress

    I recently came across an article in the Tehelka blog, which made me want to learn more. It was about a traditional water management system in the Uttarakhand region in northern India that has worked for years, but is being destroyed by funding meant to ‘modernize’ it.

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
