Biden’s rhetoric is “misleading and unhelpful,” said Michael Mann, a climate scientist at the University of Pennsylvania. The best way to view what lies beyond 1.5 C is as a continuum of worsening climate impacts, he said, rather than as a climate cliff.

“It indeed feeds doomerism since there’s a very real possibility that we will fail to limit warming below 1.5 C,” Mann said of Biden’s remarks. “If we miss that exit ramp, we don’t continue headlong down the fossil fuel highway. We get off at the earliest possible exit.”

The likelihood is that “we are going to overshoot it and come back down,” said Robert Kopp, a climate scientist at Rutgers University and contributing author to the latest IPCC report.

The risk of focusing on a particular threshold, such as 1.5 C, can encourage fatalism if efforts to meet the target fail, Kopp said.

“The danger of focusing on any threshold, particularly one there is a good chance we’re going to cross in the next 15 years, is giving people the mistaken impression that if you don’t manage to stay under that threshold, you might as well give up,” he said. “You certainly have seen people who have gone from ‘let’s not act’ to ‘well, it’s too late to act.’”

As I have pointed out previously, climate change communications is a mess and mostly a fiasco.
