All Things Considered · Extreme temperatures around the world are likely to rise dramatically as a result of global warming, a new study finds. Some heavily populated parts of the world — including the American Midwest — could face heat waves in which the temperature soars above 120 degrees by the end of this century.

These extreme heat waves are likely to kill people and crops alike.

The study, published in the journal Geophysical Research Letters, found that extreme temperatures will rise two or three times faster than average temperatures. So in Europe, peak highs could go from a sweltering 100 degrees up to 110 or 115 degrees. There's even a chance the mercury could hit Sahara-style highs of 120 degrees.

Temperatures in the 120s could also strike Australia and the American Midwest, according to the study, which used climate-change models developed for the Intergovernmental Panel on Climate Change.
