US Heat Waves To Skyrocket As Globe Warms, Study Suggests

An anonymous reader quotes a report from USA Today: As the globe warms in the years ahead, days with extreme heat are forecasted to skyrocket across hundreds of U.S. cities, a new study suggests, perhaps even breaking the “heat index.” 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. The number of days per year when the heat index exceeds 100 degrees will more than double nationally, according to the study, which was published Tuesday in the journal Environmental Research Communications. On some days, conditions would be so extreme that they’d exceed the upper limit of the heat index, rendering it “incalculable,” the study predicts. What is there to be done about this? “Rapidly reduce global warming emissions and help communities prepare for the extreme heat that is already inevitable,” report co-author Astrid Caldas said. “Extreme heat is one of the climate change impacts most responsive to emissions reductions, making it possible to limit how extreme our hotter future becomes for today’s children.”
