- Study: The Urban Heat Island Penalty Grows, Especially at Night Mon, 20 Dec 21, 5:00amFrom the Pacific Northwest National Laboratory (PNNL), more confirmation of a night-time warming bias in climate records due to increased infrastructure...
- Urban Heat Island Effects on U.S. Temperature Trends, 1973-2020: USHCN vs. Hourly Weather Stations Sat, 13 Feb 21, 1:00amI 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.
- Could Recent U.S. Warming Trends be Largely Spurious? Sun, 31 Jan 21, 1:00amThe 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...
- A New Look at the Urban Heat Island Effect Fri, 22 Jan 21, 9:00pmBy Andy May Nicola Scafetta has just published a new paper in Climate Dynamics examining evidence of the urban heat island (UHI) effect (Scafetta, 2021)...
- More surfacestations project vindication: Strong UHI temperature biases confirmed in USA Tue, 29 Sep 20, 5:39amWUWT 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...

- China is warming fastest where the cities are, not where the models predicted – classic UHI Wed, 24 Jul 19, 3:54amThe 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....
