The U.S. has contended with unrelenting temperatures this summer, and a map from NASA paints a dire picture of the scale of those persistent heat waves.
The map, which consists of a snapshot of temperatures nationwide for July 10, used satellite images — along with a complex mathematical model known as the Goddard Earth Observing System — to create a kind of color code, with dark red showing areas that reached highs of 104 degrees Fahrenheit, according to the NASA Earth Observatory, a program that examines the impact of climate change.
The results are stark, indicating potentially dangerous temperatures across nearly the entire continental U.S. The Southwest sustained the brunt of the heat, according to the map, with almost the entire region experiencing triple-digit highs.
