There are protests all over the world today in support of reversing climate change. Sponsored by the organization 350, named after the parts per million of carbon dioxide. Scientists believe that's the limit for heat-trapping carbon dioxide in the atmosphere. We're past that now and some scientists, as the New York Times notes today, think that's probably too ambitious a goal. The whole idea began with Bill McKibben, the environmental writer. Will these protests get teabagger-style coverage? Probably not. A good fight over crowd estimates always helps and so does having a television network devoted to revving up your cause. Meanwhile, it'll be interesting to see where Congress goes on climate change and how Obama handles the upcoming meeting on climate change in Copenhagen.
