Hot cities more sustainable than cold ones, study says - News - MSN CA
#SWClimate - interesting news - cities in hot SW locales more sustainable than those in cold places. http://news.ca.msn.com/top-stories/hot-cities-more-sustainable-than-cold-ones-study-says …
"The traditional view that living in hot desert areas is not sustainable should be re-examined," Michael Sivak, a research professor at the University of Michigan, Ann Arbor, told NBC News. "Because my data suggest that from this point of view — mainly a climate control point of view — living in very cold areas is less sustainable than hot areas."
He compared the energy demands for indoor heating and cooling in Minneapolis, Minn., the coldest metropolitan area in the country, with those in Miami, Fla., the warmest big city. He found the demands are 3.5 times greater in Minnesota.
..."The need for heating in Minneapolis is more energy demanding than cooling in Miami because the difference of the ambient temperature from the desired temperature is greater in Minneapolis than in Miami," Sivak explained.

In fact, he noted in a paper published Wednesday in Environmental Research Letters, the impact of warm-city living may be even more pronounced than suggested by his calculations since "people are generally more tolerant of heat than of cold."
