“Tipping points” exist only in the fevered minds and arcane computer software models of the idiot enthusiasts. The 1.5 degree “threshold” was a number picked off the wall by Hans Schellnhuber from the Potsdam propaganda mill to give the bright boys in Paris something to hang their hat on.
But as long as outlets like WaPo continue to publish this rubbish, and corrupt governments continue to put billions on the table, the BS will continue to flow unabated.
They’ve been saying this for decades now.
And as long as gullible, easily frightened little minds buy it.
