Two Oregon State University professors have doubled down in declaring a worldwide “climate emergency” and warning of “untold suffering” if fossil fuels are not eliminated.

These same authors published a similar article 20 months ago promising “untold human suffering” without deep and lasting shifts in human behavior and now lament that their warning went unheeded, meeting instead with “unrelenting business as usual.”.

As a solution to the “climate crisis,” the authors predictably propose radical modifications of human behavior, including “eliminating fossil fuels and shifting to renewables,” “switching to mostly plant-based diets,” “moving from indefinite GDP growth and overconsumption by the wealthy to ecological economics and a circular economy, in which prices reflect the full environmental costs of goods and services,” and “stabilizing and gradually reducing the population.”

On the basis of the trends they identify as “planetary vital signs,” the authors reaffirm the existence of a “climate emergency” and “call for transformative change, which is needed now more than ever to protect life on Earth and remain within as many planetary boundaries as possible.”
