  • Earth Hour: Making it Count

    Earth Hour: Making it Count

    The past Saturday 26 of March, people in 131 countries switched off their lights for an hour at 8:30pm local time to celebrate Earth Hour as a way to express their concern about the planet. Major iconic buildings and landmarks went dark, including the Empire State Building in NYC, the Beijing National Stadium (The Bird’s Nest),…

  • What Does the Science Say?

    The negotiations in Copenhagen have been handled by politicians and policy makers. But there would be no climate negotiations if climate scientists had not identified evidence that humans could disrupt the natural carbon cycle, and affect the climate system. The fact that some 50,000 people and the heads of most nations have come together indicates…

  • Abrupt Climate Change in a Warming World

    Early last month, I attended a meeting on Abrupt Climate Change in a Warming World. Climate Matters @ Columbia has discussed abrupt climate change before, referring to the hydrologic cycle, and with regards to melting sea ice or permafrost. Shifts in the earth climate are a known fact: crocodile-like reptiles lived in Greenland 55 million…

  • The latest on permafrost

    Permafrost is ground that remains at or below freezing for two or more consecutive years (for great information on permafrost see the National Snow and Ice Data Center). Climate researchers worry that permafrost will thaw as temperatures rise due to climate change, releasing carbon dioxide and methane into the atmosphere. Two recent studies indicate that this concern…

  • Snowstorms in a Warming World

    On March 2 snowstorms hit the eastern seaboard, coinciding with a widely publicized protest against the coal industry in Washington DC . This garnered some attention, with Time noting the irony of people chanting about global warming while shivering in the cold and snow. One might wonder if a March snowstorm is inconsistent with a…

  • (Almost) Ten things I learned at GROCC-6

    The sixth meeting of the Global Roundtable on Climate Change (GROCC) took place on February 26 and 27. Around 150 corporations, non-governmental organizations, and government groups have been meeting since 2005 to discuss the science, technology, and economic considerations required for sound public policies on climate change. Some commenters to our posting to announce the meeting  wondered…

  • When will we see a sea level rise of three feet?

    Recently, the Columbia Climate Center had the chance to participate in an event aiming to improve public awareness on climate change.  On the weekend of the 6th and 7th of February, the CCC had a table in the Polar Fair in the International Polar Weekend at the American Museum of Natural History. It was a…

  • Columbia Climate Center Launches its Website

    This blog, Climate Matters @ Columbia, is brought to you by the Columbia Climate Center, created in 2007 by the Earth Institute, Columbia University. The mission of the Columbia Climate Center is to integrate climate related research throughout Columbia University and to build upon it to address the challenges of understanding, predicting, adapting to, and…

  • Abrupt Climate Change, How Likely?

    Yesterday the USGS released “Abrupt Climate Change, Final Report, Synthesis and Assessment Product 3.4” of  the U.S. Climate Change Science Program and the Subcommittee on Global Change Research. You can download the four page brochure or the full report here.  Columbia scientists Edward R. Cook (the lead author) and Richard Seager, both from Lamont-Doherty Earth…
