Urban heat island effect making temperatures 8F hotter in 65 US cities

6. The heat island argument has long been used

by the right to dismiss climate change, arguing that the records show an increase only in urban environments, thus a "micro-climate" rather than global change. This is false. All indicators show a global increase in heat, with models frequently being shown to be too conservative in predictions of the rate of change. They use this heat island argument to justify the relocation of official temperature sensors away from urban centers. This pollutes the data record.

For the consistency you cite, temperature sensors should remain in their historic locations and be installed, calibrated and maintained the same.

This article shows the disproportionate impact of global heating on population centers, especially on the poor and non-white. The greater rise in urban temperatures is an early indicator of global conditions due to the greater sensitivity of the built environment. An early indicator as opposed to just an outlier.
