Alarming data and warnings about climate change have been with us for twenty years.
The issue has morphed into something like a low-level toothache. The public is numbed by all the bad news, and in place of sensible solutions, we witness the folly of political polarization. You can’t believe in climate change and be a good conservative. This departure from fact-based reality is only part of the problem. China and the U.S., who produce 40% of the world’s harmful emissions, block measures to reverse the trend toward global warming for purely selfish reasons – two rich economies want to preserve the status quo.
