I argue that, based upon the importance of quality temperature trend calculations to national energy policy, a new dataset not dependent upon the USHCN Tmax/Tmin observations is required.

The official datasets of land surface temperature are (we are told) already adjusted for Urban Heat Island (UHI) effects. But as far as I know, it has never been demonstrated that the spurious warming from urban effects have...

WUWT readers may recall that NOAA did an experiment at Oak Ridge National Laboratory that vindicated my findings about the effects of local urbanization on surface temperature measurements...

Skeptics mention the Urban Heat Island and its crickets from the ABC.

The biggest changes in temperature (“divergence” in dark red brown Fig 6) occurred where the most people lived (blue dots). In the 60 years to 2010 China was reported to have warmed by 0.79 ± 0.10 °C....

Urban Stations in GHCN V4. Guest post by Steven Mosher Background The recent post at WUWT covered a new analysis by Goddard & Tett (hereafter GT) showed how UHI has biased measurements in the UK. The paper concludes:...

I’ve been saying for years that surface temperature measurements (and long term trends) have been affected by encroachment of urbanization on the placement of weather stations used to measure surface air temperature,...
