Got any data on how many of the are placed in urban heat sinks?  As a percentage of the total?  Why aren't there more of them in the Southern Hemisphere, except for Australia?  Isn't that part of the globe?

"There are concerns raised about possible contribution from urban heat islands to global warming. Research on China[5][6] and India[7] indicates that urban heat island effect contributes to climate warming by about 30%.[8] On the other hand, one 1999 comparison between urban and rural areas proposed that the urban heat island effects have little influence on global mean temperature trends.[9] Many studies reveal increases in the severity of the effect with the progress of climate change."  [Of course, you focused on the one study that serves your agenda, when most don't.]
