As the globe warms in the years ahead, days with extreme heat are forecast to skyrocket across hundreds of U.S. cities, a new study suggests, perhaps even breaking the “heat index.”
“Our analysis shows a hotter future that’s hard to imagine today,” study co-author Kristina Dahl, a climate scientist at the Union of Concerned Scientists, said in a statement. “Nearly everywhere, people will experience more days of dangerous heat in the next few decades.”
By 2050, hundreds of U.S. cities could see an entire month each year with heat index temperatures above 100 degrees if nothing is done to rein in global warming.
The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. This is the first study to take the heat index – instead of just temperature – into account when determining the impacts of global warming, Dahl said.
