What methodology determined risks?

The study started by looking at the top 100 cities in the U.S. with a population of 200,000 or more. They looked at six factors weighted differently including sea-level rise (2.0), extreme precipitation (1.0), extreme drought (1.0), urban heat islands/extreme heat (1.0), average temperature changes (0.5) and average precipitation (0.5). With numerical values for each factor, they added up the categories and made a list of the top 25.

The report echoes findings in the National Climate Assessment published last May that identifies urban heat islands and related health risks as issues for the Great Plains/Midwest region, said Doug Kluck, central regional climate services director for National Oceanic and Atmospheric Administration’s (NOAA) National Center for Environmental Information.

“Kansas City at #5 is a bit surprisingly high,” Kluck said. “Drought, while a potential big issue for surrounding areas, may not be as severe here in the urban area due to some pretty good flows and water availability from the Missouri River. However, heat and heavier rainstorms both will make life harder for some.”
