The last couple of years have brought a long list of headlines that should alarm anyone concerned about the changing climate, from the growing number of climate-linked disasters to the resilient growth in oil and gas. But beneath those headlines another apparent trend should alarm anyone advocating for climate policy: economic conditions may be making people less willing to pay to tackle climate change. Only 38% of Americans would be willing to pay a $1 per month carbon fee to address climate change, according to new polling released Tuesday from the AP-NORC Center and the Energy Policy Institute at the University of Chicago.
