Prehistoric “Paleothermometers” Show Global Warming Risks Far Greater than Predicted –‘Palm Trees in Antarctica’

 

There are thresholds, non-linear evolutions that are not yet incorporated into current climate models. Fifty-six million years ago, the Earth experienced an exceptional episode of global warming. In a very short time on a geological scale, within 10 to 20,000 years, the average temperature increased by five to eight degrees, only returning to its original level a few hundred thousand years later.
