    Rolling a 13: Global Warming and Regional Water Management in Pakistan and Russia

    On July 28th in Peshawar, Pakistan, it rained more in one day than it had ever previously rained for the entire month. In the face of that kind of event, it’s hard not to think that we are entering unprecedented times. (It is still raining, with forecasts of more to come, with 1,600 people dead—at…

    Struggle to Keep Fish, People & Power Companies Happy

    There’s that water-energy nexus again – power plants in NYS are under scrutiny for damaging aquatic habitat and the DEC is working on a policy to limit their impact. Over 17 billion eggs, larvae and fish are killed each year, but opponents to the policy say it could cause NYS energy costs to sky-rocket.

    Supporting Continued Rebuilding Efforts in Haiti

    The Countess Moira Charitable Foundation, longtime supporter of our Earth Clinic, has made a gift to support two projects in Haiti to improve crop yields through the use of test plots and agricultural extension training.

    Global Population Growth and Water Scarcity Q&A

    Russell Sticklor with the Wilson Center’s Environmental Change and Security Program in Washington, DC. recently contacted me requesting my thoughts on a number of issues for an article he is writing on global population growth and water scarcity for the magazine, Outdoor America. I thought some of the comments might be interesting to our blog…

  • Does temperature control atmospheric carbon dioxide concentrations?

    A record of temperature and atmospheric CO2 from Antarctic ice cores shows the tight relationship between the two over the past 800,000 years (see figure). It is frequently asserted that changes in Earth’s temperature or, more specifically, the temperature of the ocean, caused atmospheric CO2 concentrations to vary over that time period. The underlying principle…

  • Dust and its Impact on Earth’s Climate System

    Last month, Columbia’s Lamont-Doherty Earth Observatory hosted a conference on dust in the climate system as part of the NOAA funded Abrupt Climate Change in a Warming World (ACCWW) project. Most often, we think of dust simply as the stuff that accumulates on our windowsills, but those fine particles floating in the air play an…

  • Urban Design Lab: Plastic TrashPatch

    How much is your trash worth?  Using various visualization instruments, design ideas, engineering, and environmental science research, a team of designers, engineers, and scientists at the Urban Design Lab (UDL) are trying to find out. A new initiative for 2010, Plastic TrashPatch, seeks to raise awareness of ”trashpatches,” thick areas of concentrated marine debris that…

  • Urbanization, Deforestation, Reforestation

    2009 was noted as the first year that more people lived in urban spaces than in rural areas.  The hope that a majority urban population would slow the clearing of tropical forests — our most effective carbon sinks — seems, however, to have been misplaced. The idea was simple: if more people moved into forested…

  • Is there hope from Copenhagen?

    Can we find positives from the United Nations Summit on climate change?  Even President Obama  admits that disappointment is justified, although the Commander in Chief claims a non-binding accord was better than a complete collapse of the negotiations. Jeffrey Sachs, fearless leader of the Earth Institute, adamantly opposed such victory proclamation from the President, for…
