Forthcoming report highlights trends in extreme heat, their implications for public health, and how major cities are preparing for a warming world
On July 25, the Union of Concerned Scientists will release a new report, Heat in the Heartland: 60 Years of Warming the Midwest, which studies weather data from 10 Midwestern cities, including Detroit, Chicago, Minneapolis, St. Louis, and Cincinnati.
The report identifies trends in heat waves over the past 60 years, discusses the health implications of these trends, and looks at what cities are doing to prepare their populations to cope with a warming world.

Summer 2012: The Heat Is On

Three cities in Michigan hit their hottest temperatures ever recorded. Chicago's three consecutive 100°+ days tied an all-time record.
- St. Louis suffered 10 consecutive days of triple-digit temperatures in late June and early July, while Cincinnati set a new all-time high of 104° for July 6.
- You could fry an egg on the sidewalk in Minneapolis on July 4, when the temperature reached 100°, and someone did.
