As brutal heat continues this summer, a report published in August by the Union of Concerned Scientists (UCS) says outdoor workers in the United States could face four times as many days with hazardous heat by mid-century if action isn't taken to reduce greenhouse gas pollution.
The report also projects a severe economic toll, with the average outdoor worker losing more than $1,700 each year because of work stoppages on days when heat and humidity top 100 degrees Fahrenheit, the point at which the Centers for Disease Control and Prevention recommends employers reduce work schedules..
