A study led by a Purdue University researcher projects a 200 percent to 500 percent increase in the number of dangerously hot days in the Mediterranean by the end of the 21st century if the current rate of greenhouse gas emissions continues. The study found France would be subjected to the largest projected increase of high-temperature extremes.
