Policy Pub: Get Ready for more Sweaty!

Dr. James Elsner participated in the Policy Pub in September 2019. To listen to his pub navigate here.

Summer is here and it’s hot. I love it. I loved summer in Milwaukee as a kid but it was always way too short. Not here. Summer starts in May and runs through most of September. Perfect. But things are changing. It’s getting hotter. By hotter I don’t mean more extreme heat. I mean more hot days and hot nights. We define a hot day as one during which the high temperature reaches or exceeds 100° F (37.8° C). A hot night is defined as one during which the low temperature fails to drop below 77° F (25° C). The official record from the Tallahassee airport shows an upward trend in the number of hot days at a rate of 2% per year and a more pronounced upward trend in the number of hot nights at a rate of 4.5% per year. Increasingly frequent hot days and nights result from more and longer hot events (consecutive hot days/nights). Read more about our research at EarthArXiv.

Dr. James Elsner is the Earl B. and Sophia H. Shaw professor and chair of the Department of Geography.
