Rising global temperatures are set to devastate food crops across the world, with particularly alarming impacts projected for the United States, where production of key crops could plummet 50% by the end of the century, according to a sweeping new analysis.
Of the many impacts of the fossil fuel-driven climate crisis, damage to the global food system is one of the most terrifying. But the overall impact of climate change on crops — and how much it can be offset by farmers' adaptations — has been hard to establish and hotly debated.
The new analysis, eight years in the making, is "the first attempt to really tackle both of those problems," said Solomon Hsiang, a study author and professor of global environmental policy at the Stanford Doerr School of Sustainability.
The scientists also measured how real-world farmers are adapting to climate change, from changing crop varieties to adjusting irrigation, to calculate the overall impact of global warming.
Their findings are stark. Every 1 degree Celsius the world warms above pre-industrial levels will drag down global food production by an average of 120 calories per person per day, according to the study, published Wednesday in Nature.
