    Urbanization is responsible for roughly 24% of the warming observed in eastern China during the past three decades, thanks to the build up of heat in cities — known as the urban heat island effect.

    Baode Chen at the Shanghai Typhoon Institute and his colleagues analysed monthly mean temperature data from 463 meteorological stations in a range of urban and rural settings between 1981 and 2007. Using both raw and reanalysed data, the team found that urbanization contributed up to 44% of the temperature increase (almost 0.4 °C per decade) in metropolises with populations of more than 1 million. The largest increase in the urban heat island effect came after the early 2000s, coinciding with a period of rapid growth of cities in China.

    heat is heat is heat. In this particular case, it is manmade. Even the most rabid climate denier would have to agree with that.

    Well that is why they correct for UHI in the GISTEMP data now isn't it.  Tamino had a nice example of the correction they have had to apply for Tokyo.
