Gernot Wagner on how to deal with climate changeby Jonathan Derbyshire / March 27, 2015 / Leave a comment
Why is it so difficult to get people to worry about climate change? After all, the science is pretty unambiguous—pace the climate change “deniers”. Part of the problem, according to a new book, “Climate Shock,” by the economists Gernot Wagner and Martin L Weitzman, is that while what we know about global warming is bad enough, there are “unknown risks that may yet dwarf all else.”
Wagner, who is lead senior economist at the Environmental Defense Fund in the United States, visited London a couple of weeks ago. I caught up with him while he was here and talked to him about the difficulties of mobilising public opinion around the threats and challenges of climate change.
GW: The big problem, frankly, is speaking the truth and talking about what scientists actually know and what they don’t know, which in many ways is even scarier. Saying the latest science out loud is [often taken to be] akin to catastrophising. That’s the big conundrum: on the one hand, “climate shock” shouldn’t be all that shocking—we’ve known this for quite a while. The problem is finding a way to state the scientific facts in a way that does not turn people off immediately.
