In case you missed it: Warmist who predicted "permanent shift to extreme heat" is an IPCC lead author

Hot time for graduation

At Stanford, Noah S. Diffenbaugh and Martin Scherer analyzed global climate computer models and concluded that by midcentury, large areas of the world could face unprecedented heat. They said the coolest summers will be hotter than the hottest ones of the 1900s.

Global warming in recent years has been blamed on increasing concentrations of gases such as carbon dioxide in the atmosphere. The permanent shift to extreme heat would occur first in the tropics and reach North America, South America and Eurasia by 2060, the scientists report in a paper that will be published in the journal Climatic Change Letters.

Stanford climate scientists forecast permanently hotter summers beginning in 20 years

Diffenbaugh was surprised to see how quickly the new, potentially destructive heat regimes are likely to emerge
