Republican Presidential candidate Rick Santorum, speaking to supporters in Gettysburg, PA last night after losing the Republican primary in Illinois to Mitt Romney. Santorum has repeatedly emphasized that he—unlike Romney and former Speaker Newt Gingrich—has always rejected the scientific consensus that man-made greenhouse gases are causing dangerous climate change. (For their part, Romney and Gingrich at best waffle on the subject, and have put forward no real plans to control carbon emissions or deal with climate change.) Santorum gave his speech on the first day of spring, following a winter that will likely go down as one of the warmest on record. For what it’s worth, yesterday’s high in Chicago was a record-breaking 85 F—37 degrees above the normal high for this time of year.
