  • 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…

  • The Landscape We Are Up Against

    We have drilled a second core through the ice to bedrock, and are done at our first site. Unfortunately, the helicopter that we need to move the heavy pieces to our second planned spot is down for regular maintenance until next Monday, June 21. That means the team must wait it out at the relatively sheltered “saddle…

  • When High Hopes Make Little Sense: Why the Hartwell Paper Fails to Deliver

    Earlier this year, 14 energy academics, analysts and advocates gathered with hopes of reinventing the way the international community treats climate policy. The result, The Hartwell Paper: A new direction for climate policy after the crash of 2009, aims to examine “all aspects of the crisis which enveloped global climate policy” last December during the…

  • The Implications of Snowcover on Climate: A Conversation with Stefan Sobolowski (Part 1)

    Stefan Sobolowski says he has always had a passion for water, weather and climate—a passion he attributes to lifetime of skiing, hiking, snowboarding, and playing in oceans. Here, Stefan discusses his research on the effects of continental snowcover on climate and why one cold winter in the United States doesn’t mean that there is no…

  • Climate News Roundup – Week of 6/7

    10 Eastern States Join Wind Energy Consortium,  Providence Business News On Tuesday a memorandum of understanding signed by Secretary of the Interior Ken Salazar and the governors of ten states established an Atlantic offshore wind energy consortium.  The goal is to promote the efficient development of wind resources on the Outer Continental Shelf from Maine…

  • Drilling the Glacier to Bedrock

    Yesterday we completed our first ice core at the Northwall Firn Glacier, down to bedrock, penetrating 30 meters through the glacier, until we hit bottom. The ice seems to contain visible layers all the way down–a sign that yearly accumulations have been preserved, instead of melding into each other. This means we should be able to…

  • Himalayan Glacier Melt: The Real Problem

    Every day I hear scientists and media people talking about climate change in a way that is often sensational or misses the real challenges. This will be a series of blogs in which I will discuss a few of these cases. Lets start with: The Himalayan Glacier Melt

  • Finally on Ice

    With the blessing of two wonderful days of clear weather, all our equipment was moved into place this morning. The ice coring can now begin. We anticipate finishing the drill assembly today and drilling by mid-morning tomorrow at three sites on the Northwall Firn glacier: the two “domes” and the saddle, where the team will…

  • Understanding Water Conflict in Central Asia, and Solutions

    A CWC research team is analyzing a complicated issue in a highly conflicted part of the world, and trying to find a way forward. They are taking an in-depth look at Central Asia (Kyrgyzstan, Tajikistan, Uzbekistan, Turkmenistan, and Kazakhstan), and the environmental, political and economic crisis building there.
