Engineering360: "Study: Impervious materials are causing cities to be hotter than rural areas"

The study, as posted, seemed to leave a big hole in the study's design. An assumption of pervious surfaces = available water for evaporative cooling, vs. impervious surfaces = no evaporative cooling, is apparent. Related variables appear to be uncontrolled or ignored. Urban "heat islands" is a phenomenon that has been well documented for many decades. The study's recommendation that urban areas would benefit from more growing surfaces is good.

This is true and not new information. Because most of the sensors in the world are in cities that are getting larger, the climate change data is skewed.

Friend,

When the data from the sensors are analyzed and correlated with sensor location the climate change data are somewhat different but still remain significantly in the same direction. So, I think I agree with you--just depends on the amount of "skew".
