Study Debunks Climate Doomsday Predictions on Crop Yields, Mass Starvation

For two decades, the public has been bombarded with dire warnings of an impending climate-induced agricultural apocalypse. The claim is that a climate warmed excessively by the carbon dioxide emissions of human activity will ravage the food supply and plunge humanity into famine and chaos.
For many reasons, none of this ever made sense. Now, a new study published in Scientific Reports has turned this narrative of catastrophe on its head, revealing that a global temperature rise of even 5 degrees Celsius (9 degrees Fahrenheit) would not reduce crop yields—and might even increase harvests.
The paper, written by economist Ross McKitrick, dismantles a key pillar of the Biden administration’s always-suspect upward revision of the “social cost of carbon”—a metric used by the U.S. Environmental Protection Agency to quantify the supposed economic damage of carbon dioxide emissions. The fivefold increase of the social cost of carbon—from $51 per ton of carbon dioxide to more than $250—was based partly on the assumption that warming would devastate agriculture.
