As temperatures surge around the world, many cities and countries are breaking heat records. Massive wildfires have ignited in Europe and the United States amid the scorching weather, destroying thousands of acres of wilderness. Hundreds have died this year between the heat and fires.

But the recent hot weather is dangerous in more subtle ways, and is an ominous signal of what increasing average temperatures and climate change portend for some of the most vulnerable who must endure the heat to earn a living. According to the Bureau of Labor Statistics, more than 15 million people in the United States have jobs that require them to be outdoors at some point, and rising temperatures are proving dangerous for them.

In Georgia, Miguel Angel Guzman Chavez, a 24-year-old farmworker, died of heatstroke while working the field last month when the heat index reached 105 degrees Fahrenheit. Earlier this month, 52-year-old Cruz Urias-Beltran was found dead in a cornfield in Nebraska after temperatures topped 100°F. Postal worker Peggy Frank died in her mail truck near Los Angeles on July 6, when the temperature reached 117°F. She was 63.

For farmworkers, delivery personnel, and construction crews, high temperatures can also mean heat exhaustion and related maladies. Between 1992 and 2016, excessive heat killed 783 US workers and seriously injured 69,374, according to the BLS.

According to the Environmental Protection Agency, the United States will lose 1.8 billion labor hours across the workforce in the year 2100 due to extreme temperatures under a business-as-usual climate change scenario. That adds up to $170 billion in lost wages.

But laborers aren’t the only ones vulnerable to heat. Researchers at the London School of Economics found that urban areas also pay a price for high temperatures, even among indoor office workers. They found that in London, a warm year could cost the city’s economy upward of 2.3 billion euros in productivity. Workers make more mistakes and act more slowly as temperatures rise above their optimal range. You can also see this effect in factories.
