I am one of the co-conspirators behind the national days of action on climate change called Step It Up 2007.  THe First day of action was on April 14, 2007, and we're now gearing up for more action this coming November 3.  Here's a brief description of the November plan:

On November 3rd we'll see which of our politicians will join us in taking on the greatest challenge of our time.  We'll gather at places across the country named after historic leaders to demand that our representatives address four key priorities to stop global warming.  It will be a historic day in every way.

Also, I am a co-auther of Fight Global Warming Now, which will be published in October of this year.
