  • Prescriptive science?

    This is just a short post to draw your attention to John Tierney’s New York Times column on John Holdren’s appointment as Obama’s science advisor. Tierney contends that: “Dr. Holdren is certainly entitled to his views, but what concerns me is his tendency to conflate the science of climate change with prescriptions to cut greenhouse…

  • Cooler, 2008 Still Ranks in the Top 10

    A paper released last week by the World Meteorological Organization reports that the preliminary global mean temperature for 2008 is 14.3°C (57.7° F). This is significantly below 2007’s 14.7°C (58.5°F), and – as Time magazine reports – the coolest year since the turn of the century. Sadly, our half-hearted efforts at carbon offsetting cannot take…

  • Climate change and the hydrological cycle

    The prospects of significant and damaging changes in the hydrological cycle due to the increase in atmospheric greenhouse gas concentrations were raised in earlier IPCC reports and restated more strongly in the most recent, 2007 Fourth Assessment Report (AR4). Now, the U.S. Climate Change Science Program (CCSP) issued its final Synthesis and Assessment Report on…

  • Abrupt Climate Shifts May Come Sooner, Not Later

    Rising Seas, Severe Drought, Could Come in Decades, Says U.S. Report

  • Around the world: Canada, Part 1

    Periodically I’ll be taking a look at how countries other than the Big Four are faring in the fight against severe global warming, as commentators tend to focus on the United States, China, India and the European Union. This is the first in a two-part post on Canada. Oh, Canada! Our enlightened neighbor to the…

  • 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…

  • Biofuels, food security, deforestation, and loss of biodiversity

    Biofuel use is one of the strategies to reduce greenhouse gas (GHG) emissions that has already been incorporated into policy and regulatory frameworks. However, it has become increasingly evident that biofuel production has unintended consequences that extend beyond national boundaries and beyond the energy sector. Chief among these are concerns for food security. The food…

  • Finance, Climate, and Faust

    I lifted the title of this entry directly from last week’s Earth and Environmental Science colloquium at Lamont. The talk, given by Dr. Berrien Moore of Climate Central, revolved around the idea that complex systems have inherent instabilities. Using the current financial situation as an example, Moore argued that such systems are marked by important…

  • Climate change law comes to Columbia

    Climate change is coming to the legal profession in a big way. And law schools are starting to notice, with Columbia Law School announcing today that it has hired environmental lawyer Michael Gerrard to head a new Center for Climate Change Law.
