Stop using the worst-case scenario for climate warming as the most likely outcome

See Climate Media vs. Climate Science: The good news is that scientists themselves have started to correct the record by Holman W. Jenkins, Jr. Excerpts:

"A drumroll moment was Zeke Hausfather and Glen Peter’s 2020 article in the journal Nature partly headlined: “Stop using the worst-case scenario for climate warming as the most likely outcome.”  

This followed the 2017 paper by Justin Ritchie and Hadi Dowlatabadi asking why climate scenarios posit implausible increases in coal burning a century from now. And I could go on. Roger Pielke Jr. and colleagues show how the RCP 8.5 scenario was born to give modelers a high-emissions scenario to play with, and how it came to be embraced despite being at odds with every real-world indicator concerning the expected course of future emissions."

"Even David Wallace-Wells, the author of 2019’s climate-crisis book “The Uninhabitable Earth,” was moved to call on fellow activists to revise their advocacy “in a less alarmist direction.”"

"A bigger moment of truth will come with a book by Steven Koonin, a theoretical physicist and chief scientist of the Obama Energy Department, demonstrating what the science—the plain, recognized, consensus science—says about climate change: It won’t be catastrophic. It’s unlikely to be influenced in a major way by policy actions. The costs will be large in relation to everything except the future, richer economy that will easily pay for them."
