Claiming "societal collapse brought about by a collapse of global harvests before 2050" is a "deeply unlikely outcome" helps nobody. The question is: are we in a rapid minor/major mass extinction with societal collapse(s) due to a range of overlapping factors already beginning?

1. 'Large negative impacts' on food production at 2°C according to IPCC report AR6, the consensus on climate science 2. "Mass death" of billions of people will be certain at 3°C according to at least one IPCC Lead Author of AR6 3. 'Extinction' at 3-4°C by the 2050s? Plausible.

We've got a new pre-print just out The Economics of Climate Adaptation Optimism led by @matthewgburgess with @PatrickTBrown31 @mattkahn1966 Check out Matt B. for some excellent threads on the paper More summaries coming soon to S*bsta*ck! osf.io/preprints/soca…



2°C by 2030-55, then 3°C by 2048-83 (SSP5-8.5). 2°C by 2046, then 3°C by 2092 (SSP2-4.5). esd.copernicus.org/articles/12/25…

Establishment scientists are lying to themselves and to all of us. 3°C and rising is close. Mass media newspapers should have this chart on their front pages every day.

BREAKING: scientists agree risk of worst-case 2°C global warming by 2030-55 (still totally ignored by mass media) is now painfully clear, extreme, and intensifying

Dear Journalists, What will be the consequences of 2°C and rising by 2030-55? 'Large negative impacts' on food production? "Mass death" of billions of people? 'Extinction'?
