Reuters | Heat Waves to Worsen Across America, Europe

According to an NCAR study:

"The average Paris heat wave lasting eight to 13 days, they predict, will last 11 to 17 days. In Chicago, heat waves will last on average a day longer, from eight days to nine days, and there will be two a year by 2080 instead of about one.

'But other areas (e.g. northwest United States, France, Germany and the Balkans) could see increases of heat wave intensity that could have more serious impacts because these areas are not currently as well adapted to heat waves,' the researchers wrote."

Bad news if the model is accurate.
