“New research from First Street Foundation analyzes the the prevalence of increasing extreme temperatures and dangerous heat wave events throughout the contiguous United States, with a key finding being the incidence of heat that exceeds the threshold of the National Weather Service’s (NWS) highest category for heat, called “Extreme Danger” (Heat Index above 125°F) is expected to impact about 8 million people this year, and grows to impact about 107 million people in 2053, an increase of 13 times over 30 years. This increase in “Extreme Danger Days” is concentrated in the middle of the country, in areas where there are no coastal influences to mitigate extreme temperatures. The First Street Foundation Extreme Heat Model (FSF-EHM) was built using datasets from the US Federal Government, augmented with publicly available and third party data sources, and existing research and expertise on heat modeling. The model estimates localized heat risk at a 30-meter resolution across the United States today and 30 years into the future, creating a high- precision, climate-adjusted heat model that provides insights at a property level. Its analysis combines high-resolution measurements of land surface temperatures, canopy cover, impervious surfaces, land cover, and proximity to water to calculate the current heat exposure, and then adjusts for future forecasted emissions scenarios. This allows for the determination of the number of days any property would be expected to experience dangerous levels of heat…”
