By Paul Homewood Not only is the UK Met Office desperate to declare a new record temperature from an extremely dodgy site in Cambridge, but a newly claimed record temperature in Germany also appears to be a cheat: During last week’s record-setting European heat wave, Germany’s previous record of 40.3C was impressively […]
. . . One “cause” of rising average global temperatures is the urban heat island effect. Cities are hotter than rural areas. Many of the reporting stations that were once in undeveloped rural areas have experienced either suburban or urban development, or the stations have been moved to more urban settings. It is well documented that some have been, seemingly intentionally, relocated near or at heat sources such as paved parking lots and air conditioners.
One reason for relocation near buildings or other structures could be that new automatic-reporting equipment needs to be connected by cable. Rather than dig up parking lots or roads to install units in a grassy or protected area, many have opted to locate them where they can be directly connected without involving costly excavation, although such sites do not meet the stated requirements. Instead of excluding data from stations that are poorly situated, a convoluted mathematical algorithm (scheme) is used to “correct” it to presumed pre-industrial levels. See illustrations below.
One additional problem with the newer sensors is their fast response. Since they record the high and low temperature point each day, not the average, they can report a transient heat source like a passing bus, an idling auto or jet engine exhaust at the airport instead of the actual ambient temperature.
Urban area plus mathematical correction algorithm equals pristine nature

Proposed rating of reporting stations with regard to surroundings:
Figure 3. U.S. Historical Climate Network (USHCN) station exposure at sites representative of each CRN class: CRN 1, a clear flat surface with sensors located at least 100 m from artificial heating and vegetation ground cover <10 cm high; CRN 2, same as CRN 1 with surrounding vegetation <25 cm and artificial heating sources within 30 m; CRN 3, same as CRN 2, except no artificial heating sources within 10 m; CRN 4, artificial heating sources <10 m; and CRN 5, sensor located next to/above an artificial heating source.

Guest essay by Eric Worrall Genius cartoonist Scott Adams published a Sunday cartoon panel offensive to the climate religion. From “Climate Change ” is the new universal boogeyman department. Just in case you think this cartoon is too ridiculous to be true, there are plenty of real world examples of people trying to blame climate…
No country has ever powered itself entirely with wind and solar. No country ever will. The image above is not the crazed doodlings of a maniac, it’s the combined output of every wind turbine connected to Australia’s Eastern Grid last month thanks to Aneroid Energy. Note the numerous occasions when output plummets by 2-3,000MW in minutes, […]

By Paul Homewood h/t Dennis Ambler A welcome voice of common sense! Much of industry needs plentiful supplies of low cost energy. Industry is about transforming basic materials taken from the earth into materials, and then cutting, shaping and assembling these into manufactured goods. Transformation of silica into glass or iron […]
Leftists like Bill McKibben of 350.org suffer from irrational fantasies that lead them to believe that we can move society forward without all the benefits that petroleum brings to our modern society. They’re dead wrong of course, and this short humorous video illustrates just what life might be like without the many products and energy […]
