The risk of climate change is real, immediate, and very serious. If the vast majority of the doctors I consulted told me that consuming copious amounts of butter significantly increased my risk of a heart attack, I would take out a little “insurance” and cut back on my butter consumption. It is of course possible that the 95%+ of scientists who have explored the topic and the National Scientific Academies of every major nation are mistaken, and that the uncontrolled emissions of greenhouse gases pose no risk of destabilizing the climate. Personally, I hope so. But I don’t think it makes any sense to gamble that this is the case.
