This type of thing isn't new, also its one of the confounding factors in analyzing global warming. Many of the temperture readings, esp. many of the older ones are now in built up areas that used to be rural or low density suburban areas. The readings go up even though the warming is only local. Tim, the article is more than about urban temps. rising. It fits that areas of dense human habitation would result in higher temps. The real point of the article is that the weather has been modified for those localized areas of higher density and the changes are becoming more apparent. From that, one can extrapolate that these higher temps have contributed to the relatively recent rise of global temps. One can further extrapolate that if the weather can be changed for a geographic area as small as that required by a city than its very likely the weather for the entire planet is effected by rising temps. So far, the impact on city areas has been fairly benign. However, there is no guarantee that will continue; in fact, its not likely given the fine balances that exist in nature. ted
