Hot future shock: Heat wave temperatures to soar

WASHINGTON – During the European heat wave of 2003 that killed tens of thousands, the temperature in parts of France hit 104 degrees. Nearly 15,000 people died in that country alone. During the Chicago heat wave of 1995, the mercury spiked at 106 and about 600 people died.

In a few decades, people will look back at those heat waves “and we will laugh,” said Andreas Sterl, author of a new study. “We will find (those temperatures) lovely and cool.”

Sterl’s computer model shows that by the end of the century, high temperatures for once-in-a-generation heat waves will rise twice as fast as everyday average temperatures. Chicago, for example, would reach 115 degrees in such an event by 2100. Paris heat waves could near 109 with Lyon coming closer to 114.

His study projects a peak of 117 for Los Angeles and 110 for Atlanta by 2100; that’s 5 degrees higher than the current records for those cities. Kansas City faces the prospect of a 116-degree heat wave, with its current all-time high at 109, according to the National Climactic Data Center.

It could be worse. Delhi, India is expected to hit 120 degrees; Belem, Brazil, 121, and Baghdad, 122.
