Charles Redman, of the UREx SRN, speaks to KTAR news about the network and its plan to make cities, like Phoenix, more resilient towards heat.

Phoenix is known for its sweltering summer days and increasing daytime temperatures; however, its nighttime lows are increasing at an even more rapid pace. Redman explains that at some point we will cross a threshold of what people, plants, and animals can cope with, and it will come down to how we utilize our resources to find a solution.
