Extreme Heat Drives Up Food Prices. Just How Bad Will It Get?

Introduction:
(Grist) Sometimes climate change appears where you least expect it — like the grocery store. Food prices have climbed 25 percent over the past four years, and Americans have been shocked by the growing cost of staples like beef, sugar, and citrus.
While many factors, like supply chain disruptions and labor shortages, have contributed to this increase, extreme heat is already raising food prices, and it’s bound to get worse, according to a recent study published in the journal Communications Earth & Environment. The analysis found that heatflation could drive up food prices around the world by as much as 3 percentage points per year in just over a decade and by about 2 percentage points in North America. For overall inflation, extreme weather could lead to anywhere from a 0.3 to 1.2 percentage point increase each year depending on how many carbon emissions countries pump into the atmosphere.
Though that might sound small, it’s actually “massive,” according to Gernot Wagner, a climate economist at Columbia Business School. “That’s half of the Fed’s overall goal for inflation,” he said, referencing the Federal Reserve’s long-term aim of limiting it to 2 percent. The Labor Department recently reported that consumer prices climbed 3.2 percent over the past 12 months.
The link between heat and rising food prices is intuitive — if wheat starts withering and dying, you can bet flour is going to get more expensive. When Europe broiled in heat waves in 2022, it pushed up food prices that were already soaring due to Russia’s invasion of Ukraine (known as the breadbasket of Europe), researchers at the Europe Central Bank and Potsdam Institute in Germany found in the new study. Europe saw a record-breaking 9.2 percent inflation that year, and the summer heat alone, which hurt soy, sunflower, and maize harvests, might have been responsible for almost a full percentage point of that increase.
To figure out how climate change might drive inflation in the future, the researchers analyzed monthly price indices for goods across 121 countries over the past quarter-century.

caltrek's comment: Aside from some plans of dubious benefit to plant trees, Republicans ignore global warming while Democrats recognize it as a threat and seek to actively mitigate the problem. Yet, Republicans are credited with better managing the economy. Go figure.
Don't mourn, organize.
