  • We Can’t Separate Climate and Biodiversity

    In 1940, after Copenhagen was occupied by Nazi Germany, many of its Jews were saved when Danes and Swedes cooperated to spirit them at night across the narrow strait from the Danish town of Helsingør to the Swedish town of Helsinborg. On the Danish side of the strait, there is now a monument, lit at…

  • Why Copenhagen Will, and Should, Fail

    One of the main scientists who convinced world leaders to take note of climate change says that the Copenhagen talks are so flawed, it would be better if they collapse so the process can resume from scratch. James Hansen, director of the Goddard Institute for Space Studies (an Earth Institute affiliate) told The Guardian newspaper,…

  • End the Politics. Let Scientists and Engineers Lead.

    We can only marvel at the disarray. Here we are, 17 years after the signing of the UN framework convention on climate change, two years after the decision in Bali to agree a new climate policy, one year after Barack Obama’s election, and days out from the Copenhagen conference. Yet a real global strategy to…

  • The Poor Need Climate Solutions Now

    Two broad pieces must be part of any world climate agreement. The one you hear the most about so far is mitigation: cutting emissions of greenhouse gases. The other–perhaps more pressing–is adaptation: measures we must take to adjust agriculture, infrastructure and economies to changes already happening. We do not have to look to the distant…

  • Adapting Is the Key

    By Clare Oh Stephen Zebiak, director general of the International Research Institute for Climate and Society (IRI), is in the business of helping societies adapt to changing climate: adjusting farming methods and crops, tackling climate-sensitive diseases such as malaria, and protecting low-lying areas from sea-level rise. Clare Oh of the Columbia University Record talked with…

  • Cities Can Lead Nations

    By Cynthia Rosenzweig At the Copenhagen climate summit, nations must answer a call for action—but local governments may help show the way. Climate change is no longer predicted; it has arrived. A plethora of studies shows that global changes in physical and biological systems are being caused by human-induced warming. Building on the 2007 Intergovernmental…

  • Our Leaders Can Run, But They Can’t Hide

    As the nations of the world prepare to meet in Denmark, there is some well publicized noise being emitted to lower expectations for a climate treaty. The United States and China—the two largest emitters of greenhouse gases, with over 40% of the world’s pollutant load–appear to be at the center of this effort at political…

  • 30 Rock and Responsible Energy Use

    NBC’s Green Week 2009 featured an entertaining energy challenge for the characters of 30 Rock, when Jack tasks Kenneth and the office with reducing the show’s energy consumption by five per cent. Here are some highlights of how characters committed to help the cause. Liz Lemon: Agrees to remove the mini fridge from her office…

  • Four Times Around the World in 40 Days

    For the first time in more than 40 days, the nose of the NASA DC-8 is pointing north after taking off from Punta Arenas airport. We have completed our Antarctic survey flights and are heading back home to Palmdale, California. But before we start climbing to cruising altitude we are flying at 300 ft above…
