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.

Could Recent U.S. Warming Trends be Largely Spurious?
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…
More surfacestations project vindication: Strong UHI temperature biases confirmed in USA
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. The urban…

Quote of the Week: That time when climate science believed UHI was causing most of the twentieth century warming
AMS fellow Joe D’Aleo writes of a time when Thomas Karl, former director of the National Climatic Data Center (NCDC) actually believed that UHI and station siting was a problem…

Is Fighting Global Warming the Solution to Water Shortages in Malawi (or Elsewhere)?
Guest essay by E. Calvin Beisner In late May two evangelical environmentalists, recently returned from visiting Malawi, published articles in which they said poor Malawians are suffering from reduced rainfall…
The Chinese demonstrate that UHI has a real and essential effect on regional climate change
Study finds that urbanization has considerable influence on the regional climate change, they even blame proximity to air-conditioning as a factor. Press release from Science China Press (full paper follows)…
Climate Craziness of the week – with the physical signature of UHI staring them right in the face, Mann & Borenstein go with their 'gut' instincts
Some people wonder if Michael Mann is simply an activist masquerading as a scientist, this lends credence to that idea. I wonder if Dr. Mann has ever visited weather stations…

Station bias – an old problem
A number of readers have commented about the story from Sunday about NOAA’s experiment at Oak Ridge Laboratory to determine the warming effects of siting suggesting that the experiment was…
Via experiment, NOAA establishes a fact about station siting: 'nighttime temperatures are indeed higher closer to the laboratory'
WUWT readers may recall that I wrote about this experiment being performed at Oak Ridge national Laboratory to test the issues related to station siting that I have long written…
Unique paper looks for natural factors in station data–shows significant probabilities of natural signal
