In 2015, when about 50,000 people flew to Paris in order to attend yet another conference of the parties at which they were to strike, we were assured, a “landmark”—and also “ambitious” and “unprecedented”—agreement, and yet the Paris accord did not (could not) codify any specific reduction targets by the world’s largest emitters, and it would, even if all voluntary non-binding pledges were honored (something utterly improbable), result in a 50 percent increase of emissions by 2050.[80] Some landmark.
