In summer 2009, Senators Barbara Boxer (D-Calif.) and James Inhofe (R-Okla.) butted heads in what was to be the last Senate hearing on climate change for three years. Then, the debate was over pending climate change legislation, with both sides firing off the usual arguments: obstructionism by the right and overspending by the left. The two powerhouse legislators locked horns again yesterday on climate change for the first time since then, but this time the argument amongst members of the Senate Environment & Public Works Committee was back to climate kindergarten: Is it actually happening?
Fortunately, there were actually a few climate scientists on hand, including IPCC lead author Christopher Field and Harvard oceanographer James McCarthy, along with John Christy, an Alabama climatologist tapped by Sen. Jeff Sessions (R-Ala.) to lead the denial side. Later, the panel heard from a trio of business and civic planning officials, who testified on the public health risks posed by climate change and on ways private enterprise can adapt (or not).
