About one half of all land surface temperature measurements used to show global warming and promote the command-and-control Net Zero agenda are taken near or adjacent to airport runways. This amazing fact from research by Professor Ross McKitrick casts further serious doubt on the validity of three major global temperature datasets, including the one compiled by the Met Office, which continue to show higher global temperatures compared with other reliable measurements made by satellites and meteorological balloons.
Airports are arguably uniquely unsuitable for providing an insight into global temperatures. Many of them are major industrial complexes spread over miles of heat-radiating tarmac and concrete, containing industrial buildings and subject to constant super-heated jet exhausts measuring hundreds of degrees centigrade.
There are three major global surface datasets. HadCRUT is compiled by the University of East Anglia Climate Research Unit in collaboration with the Met Office, NASA runs the Goddard Institute for Space Studies GISS record, while NOAA is compiled by the U.S. national weather service. All three global averages depend on the same underlying land data from the Global Historical Climatology Network (GHCN). As I have noted on numerous occasions, all three datasets have made significant adjustments, which has had the effect of increasing recent warming and cooling the historical record.
