Hottest Year Ever in Australia? Not according to the satellites. By Joanne Nova.
For forty years NASA satellites have been circling the Earth covering our landmass day and night. But yet again, the Australian Bureau of Meteorology has released the obligatory “hottest ever year” media release without mentioning that it wasn’t the hottest year in the far more accurate satellite record of Australia, and that this new “record” depends entirely on adjustments and quite possibly on ignoring all the data recorded in the 1800s. …
So to help them out I’ve graphed UAH satellite temperature record which shows that last year was the 4th hottest year since 1979 when the UAH satellite data set begins.
Perhaps in 2020 the Australian Bureau of Meteorology will set their own record, and explain for the first time how and why they adjust their data continuously and post hoc. The Australian surface data is all changed with a mystical secret technique that cools historic thermometers in paddocks, warms them in cities, and can’t be explained to anyone outside the sacred BOM guild (see the marvel of homogenization).
They also might explain why they insist on ignoring the superior satellite data and try to measure a vast continent with flawed surface stations placed next to airport tarmacs, car parks, asphalt, incinerators, skyscrapers, super highways, and basically in sites and that are often not compliant with the BOM’s own standards and using super fast electronic sensors in a way that is not WMO compliant either. Let’s not forget they also get data from boxes that are a quarter of the original size, that move all the time, and that many modern records are just meaningless electronic one second “moments” that could never have been recorded in 1910 (or even in 1980).
The BOM measures Australia’s temperature using a network of scattered thermometers, many badly sited near artificial heat sources, many in urban areas that are warming merely due to urbanization. They sample the temperature over a tiny proportion of Australia. The bureaucrats then adjust the individual temperatures by their own secret methods (no audits please) to arrive at the overall temperature.
The satellites measure the temperature of the air above all of Australia, every couple of hours. No adjustments or special sauce.
Which sounds more reliable to you?
