  • Climate skeptic plays hookey

    The great climate debate was supposed to be yesterday, but it was not to be. My opponent, Dr. Tim Ball, was a no-show. He knew the debate started at 2:00 p.m., but got the time zone wrong. After he figured that out, his phone stopped working. Go figure.

    So it was just me, and I spent about 75 minutes answering questions that readers had left on Eric Berger's Sciguy site, as well as taking questions from the phone lines. Many of the questions were interesting and reasonable, and I very much appreciate the people that posed them.

    However, what would a climate change debate be without a few wackos?

    One caller asked (and later emailed me the same question):

    I would like to know if you really believe you and others like you can manage the climate of this planet? As the Wizard of Oz found out, there are unforeseen consequences to your actions.

    That's right, if the Wizard can't make good policy concerning flying monkeys, witches, and Judy Garland, what chance do we have of handling climate change? This caller will most definitely not like my suggestion that we geoengineer a cooler climate by sending up flying monkeys carrying mirrors to reflect sunlight back to space.

  • Climate skeptic steps up

    We've finally found someone willing to debate me: Tim Ball, a retired professor from the University of Winnipeg. The debate will be online Monday, Dec. 17, at 2 p.m. CST.

    You will be able to listen online through BlogTalkRadio's service. In fact, you can even call in during the show (see the BlogTalkRadio web site for details). You can also post questions on SciGuy Eric Berger's website.

    I realize that these types of events don't do much to move the climate debate forward. I'm mainly doing this to test my own ability to answer the skeptic's questions and see how I fare in this type of activity.

    For those who miss it live, it will be archived in mp3 format.

  • NASA has bold plans to … send rodents into orbit

    A while back I blogged on the folly of NASA's Moon-Mars program, and how it's killing real science the agency could be doing. Yesterday I received an email from NASA alerting me to a new funding opportunity:

  • U.S. emissions go down!

    The White House issued a press release yesterday about the report (PDF) by the Energy Information Administration that U.S. greenhouse-gas emissions for 2006 were 1.5 percent below the 2005 level. Here is the text of the press release:

    STATEMENT BY THE PRESIDENT

    I was pleased to receive the Energy Information Administration's final report today, which includes U.S. greenhouse gas emissions for 2006. The final report shows that emissions declined 1.5 percent from the 2005 level, while our economy grew 2.9 percent. That means greenhouse gas intensity -- how much we emit per unit of economic activity -- decreased by 4.2 percent, the largest annual improvement since 1985. This puts us well ahead of the goal I set in 2002 to reduce greenhouse gas intensity by 18 percent by 2012.

    My Administration's climate change policy is science-based, encourages research breakthroughs that lead to technology development, encourages global participation, and pursues actions that will help ensure continued economic growth and prosperity for our citizens and for people throughout the world. Since 2001, we have spent almost $37 billion on climate science, technology development, and incentives and international assistance. Recently, we convened representatives of the world's major economies -- the largest users of energy and largest producers of greenhouse gas emissions, from both developed and developing nations -- to discuss a new international approach on energy security and climate change. Our aim is to agree on a detailed contribution for a new global framework in 2008 that would contribute to a global agreement under the United Nations Framework Convention on Climate Change by 2009. The United States looks forward to working with partners to reach consensus on a "Bali Roadmap" at the upcoming UN meeting on climate change in Indonesia in December.

    Energy security and climate change are two of the important challenges of our time. The United States takes these challenges seriously, and we are effectively confronting climate change through regulations, public-private partnerships, incentives, and strong investment in new technologies. Our guiding principle is clear: we must lead the world to produce fewer greenhouse gas emissions, and we must do it in a way that does not undermine economic growth or prevent nations from delivering greater prosperity for their people.

    There are a few noteworthy aspects to the report and this press release.
