The streets of Phoenix are not just metaphorically on fire; a new set of thermal infrared imagery from NASA paints a stark picture of the real heat blanketing the city's asphalt, with ground temperatures soaring to a sizzling 160 degrees. Gathered using a thermal radiometer aboard the International Space Station, the visuals showcase a spectrum of urban heat on a day when the mercury tipped at a high of 106 degrees.
The areas sprawling across Phoenix, coded in hues reflecting their respective scorching temperatures, were captured last June 19, a day oppressive with an a actual high temperature that the registrar only as 106 degrees. Yet the images reveal a more brutal story; spots where sidewalks and streets, ruthless in their absorption of solar energy, reached heights between 120 and 160 degrees. The ramifications of these elevated temperatures are severe - the Arizona Burn Center – Valleywise Health points to a spike in burn injuries over recent years, with the average patient enduring a 12-day hospital ordeal. Tragically, 10% of the 136 patients treated last year succumbed to their injuries, as reported by AZPM News.
In stark contrast, areas with more vegetation report starkly lower temperature - Encanto Park and similar verdant areas offer a breath of cooler air on the map. The data reaffirms the cooling effect of green spaces in combating the urban heat island effect. Meanwhile, neighborhoods that have skimped on greenery, like Maryvale and regions encircling Sky Harbor Airport, bore the brunt of the infernal heat.
The startling numbers and images have kicked up discussions on urban planning and the critical role of green spaces in providing not just aesthetic value, but also a much-needed cooling effect. While the searing heat continues to be a pressing concern for Phoenix residents, the NASA data underscores the disparities in temperature across different city zones and stresses the importance of implementing strategies to mitigate the consequences of the relentless sun.
