Watts et al 2012: Urban Heat Island (UHI) Has A Huge Effect On Surface Temperature Data

A new paper by Watts et al 2012 on U.S. surface temperature records:

“Anthony has led what is a critically important assessment of the issue of station quality. Indeed, this type of analysis should have been performed by Tom Karl and Tom Peterson at NCDC, Jim Hansen at GISS and Phil Jones at the University of East Anglia (and Richard Muller). However, they apparently liked their answers and did not want to test the robustness of their findings.

In direct contradiction to Richard Muller’s BEST study, the new Watts et al 2012 paper has very effectively shown that a substantive warm bias exists even in the mean temperature trends. This type of bias certainly exists throughout the Global Historical Climate Network, as well as what Anthony has documented for the US Historical Climate Reference Network.”

Ian Plimer: “Humans can change the weather. The ‘urban heat island’ effect shows that the concentration of roads, concrete, buildings and machinery in towns of more than 1000 inhabitants creates a warmer setting than in a rural setting. In Europe, we see a ‘winter weekend effect’ where cooler wetter weather probably results from human activity. These weather changes do not necessarily mean that humans change climate.”
