Gingrich: ‘I Actually Don’t Know If Global Warming Is Occurring’

Appearing on Fox News Tuesday night, Republican presidential candidate Newt Gingrich said his ad with Nancy Pelosi on global warming for Al Gore’s Alliance for Climate Protection was the “dumbest single thing I’ve done in years.” “I actually don’t know whether global warming is occurring,” he continued, although he conceded the National Academy of Sciences says it is happening. Gingrich has flipped back and forth on concern for global warming since 1989. Since then, global warming has nearly doubled.
