What worries me is the widespread misperception that we can do anything substantial about carbon emissions without seriously compromising economic growth. To be sure, forcing a reduction in CO2 emissions will help spur investment in new energy technologies. But so does a price tag of $126 for a barrel of oil. Finding a replacement for carbon-based energy will require a huge investment of wealth, and destroying wealth is not a very good first step toward that goal.

When the public finds out how much any legislation that punishes energy use is going to cost them, with no guarantee that anything we do will have a measurable impact on future climate, there will be a revolt just like the one now materializing in the U.K. and the EU. At some point, as they are faced with the stark reality that mankind’s requirement for an abundant source of energy cannot simply be legislated out of existence, the public will begin asking, “Just how sure are we that humans are causing global warming?”
