The prevailing climate change narrative took a big hit in recent days, as scientists who comprise the United Nations’s Intergovernmental Panel on Climate Change are backing away from more outlandish climate predictions for the 21st century.

Extreme forecasts of rising temperatures of 4 to 5 degrees, the scientists wrote in the journal Geoscientific Model Development, “have become implausible.” That means predictions of rapidly growing carbon emissions and higher temperatures, supposedly leading to fast-rising sea levels, floods, crop failures, and even human extinction scenarios, are finally being jettisoned.
