    The Southern Ocean Is Breathing in Carbon Dioxide at a Healthy Rate

    “In the last 10 years, we were afraid that the Southern Ocean was going to quit giving us a break from climate change. This study shows that it’s recovered its ability to take up carbon dioxide, and that’s good news.”

    Q&A: Park Williams on Drought, Climate and ‘Cracking the Code’

    “Future extremes are going to occur more and more frequently. In planning, we don’t need to plan for the 2 degree warming that we are aiming for as a globe, we need to plan for the 10 degree increase in a day, or the year when there’s no water. We need to plan for worst-case…

    Learning from a River’s History to Prepare for the Future

    Researchers from eight universities, including Columbia University, are using tree ring and glacier analysis to reconstruct the climate history of the Missouri River Basin in order to give policymakers and water managers better decision-making tools to manage the river.

  • Hillary Clinton Is Right on Climate Change and the New York Times Is Wrong

    I would argue that given human behavior and organizational inertia it is better to subsidize something new than tax something old. A subsidy, like a sale, sometimes stimulates changed behavior. But a tax may or may not influence behavior.
