We’ve known for a very long time that human beings are very sensitive to temperature, and that their performance declines dramatically when exposed to heat, but what we haven’t known until very recently is whether and how those lab responses meaningfully extrapolate to the real-world economy,” said R. Jisung Park, an environmental and labor economist at the University of Pennsylvania. “And what we are learning is that hotter temperatures appear to muck up the gears of the economy in many more ways than we would have expected.”
A study published in June on the effects of temperature on productivity concludes that while extreme heat harms agriculture, its impact is greater on industrial and other sectors of the economy, in part because they are more labor-intensive. It finds that heat increases absenteeism and reduces work hours, and concludes that as the planet continues to warm, those losses will increase.
The cost is high. In 2021, more than 2.5 billion hours of labor in the U.S. agriculture, construction, manufacturing, and service sectors were lost to heat exposure, according to data compiled by The Lancet. Another report found that in 2020, the loss of labor as a result of heat exposure cost the economy about $100 billion, a figure projected to grow to $500 billion annually by 2050.
