I agree with the author’s claim that climate change is not an existential risk for humanity. Still, both the title and subtitle bother me. The alarm does not seem to be a false one, even if many of the worriers make grossly overstated claims about the end of the earth. And right now “climate change panic” is not costing us “trillions,” rather virtually all countries are failing to reduce their carbon emissions and most are not even trying very hard.
There should be more of a focus on the insurance value of avoiding the worst plausible scenarios, which are still quite bad. There is no argument in this book which overturns the Weitzman-like calculations that preventive measures are desirable.
I can report that the author endorses a carbon tax, more investment in innovation, and greater adaptation, with geoengineering as a back-up plan, more or less the correct stance in my view.
There is much in this book of value, and the criticisms of the exaggerated worriers are mostly correct. Still, the oppositional framing of the material doesn’t seem appropriate these days, and Lomborg will have to choose whether he wishes to be “leader of the opposition,” or “provider of the best possible message.” Or has he already chosen?
