I recently received a request to join Pennsylvania scientists and economists in signing a "call to action" letter on global warming that will be presented to state legislators in the coming weeks. I thought readers might be interested in the letter and my reasons for not signing the letter. Below is the "call to action" letter and my response to the organization follows.
You can get more information about the letter and the organization at http://www.ucsusa.org/global_warming/solutions/big_picture_solutions/pennsylvania-call.html
