Climate Change Forum: More impacts to come, but some already ‘in the rear view mirror’

In the 1970s, climate change activist Rafe Pomerance said, “nobody ever heard of the problem. … Now, there’s total recognition globally. The advance in the recognition recently is huge because … many of the impacts that were forecast in those assessments at that time have come to pass. We’re now see climate change — the forecast, still in the windshield, but we’re seeing impacts in the rear view mirror.”

Pomerance and David Roberts, who covers energy and climate change for Vox, spent about an hour talking about climate change challenges and potential solutions at “Energy Policy Then and Now,” a forum produced by the University of Pennsylvania’s Kleinman Center for Energy Policy, Sept. 12 in Philadelphia.
