  • World Water Day – Let’s All Pull Together

    Today, Monday, March 22 is World Water Day.  It’s great to see the heightened attention to water issues, even if just for the day.  The Huffington Post is featuring numerous WWD-related articles and in a recent check, “World Water Day” was the 75th most popular Google search.   Virtually every WWD article I’ve seen cites similar statistics, which…

  • Water Scarcity Conflicts Loom, but also Potential Cooperation

    Regions likely to become drier because of climate change include Central Asia and northern Africa. Up to 250 million people in Africa could suffer extra stress on water supplies by 2020, according to the U.N. panel of climate experts.

  • Water Human Rights: Pollution

    In my previous blogs, I have been discussing different ways in which the human right to clean water is violated. I have already discussed how economic scarcity occurs, and this week I will be discussing pollution of water. Pollution issues are largely leading to contamination of the water supplies around the world.  There are countless…

  • Osmotic power — prospect of sustainable energy, or water liability?

    Today, Statkraft, a company in Norway, opened the world’s first osmotic power plant—a model of a sustainable energy system which uses osmosis to harness the energy of fresh water’s natural movement toward salt water through a membrane. The idea for power generated through the movement of water, due to osmosis through a specially designed membrane,…

  • Water Human Rights: Physical Scarcity

    In my previous blogs, I defended water as a human right and began the discussion of ways in which the human right to clean water is violated. I have already discussed how economic scarcity occurs, and this week I will be discussing physical scarcity of water. Physical scarcity is the issue that the water just…

  • Water Human Rights: Economic Scarcity

    In my earlier blog, I began arguing that water is a human right, and that the extreme lack of potable water is a significant human rights violation.  The scale of the human rights violation of the right to drinking water is on an extremely large scale. The largest occurrence of this right being violated is…

  • Water Reflections: Crisis of water supplies in New Delhi, India

    Written in collaboration with Meghna Bhattacharjee. Failed monsoon rains put a cloud over the Columbia Water Center’s journey to India this summer. Soaring temperatures hitting 40 degrees Celsius with 100% humidity made for a hazy sweltering experience which begged for some precipitous relief.  As we traveled around New Delhi from air-conditioned cars to air-conditioned rooms,…

  • California’s other crisis

    The “Golden” State doesn’t seem so golden these days. LA’s recent wildfires and Sacramento’s recent budget crises have left a dark cloud hanging over the state. Compounding the state’s financial woes and charred image is a problem potentially even more challenging: drought. Since 2000, the state’s reservoirs have been depleted and current climate change projections…

  • India: the Impact of the 2009 Monsoon Failure

    This article is the second in a series inspired by the recent Columbia Water Center trip to India During our recent CWC trip to India (during the first three weeks of August) one news story dominated all others: this year’s near total failure of the monsoon.  Many of us in the West don’t really understand what…

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
