Researchers have found that the amount of green space and shade in a neighborhood can significantly shape temperatures. On average, neighborhoods with more trees and green space — instead of impermeable surfaces like pavement — can run anywhere from 1 to 7 degrees Fahrenheit cooler. The phenomenon, which has been well studied in major urban cities, is called the “heat island effect.” But researchers have done far less work examining how those trends play out in more rural parts of the country.
Missoula, Montana, is helping fill that gap. In 2024, Climate Smart Missoula, a local nonprofit, teamed up with the city and county of Missoula and secured federal funding for a heat mapping initiative. Last summer, teams of volunteers drove countywide transects with sensors recording second-by-second measurements of temperature and humidity. Then analysts with the climate adaptation consulting firm CAPA Strategies turned the data into a now-publicly available heat map for the county. It’s the first of its kind for the state and this region of the Rockies. (Cities in Wyoming, No... Read more
