Heat waves are nothing new.
It is often said that many people do not read the minutes of the last meeting.
For days now we have been hearing, about “unprecedented heat” and record temperatures. Naturally the government science and media arms are quick to blame carbon dioxide or man-made global warming for this (and every other unusual weather event).
Firstly, when the Australian Government Bureau of Meteorology (BOM) reports a “record” temperature, they mean “since 1910 in BOM’s adjusted records”. They ignore all records earlier than 1910 on the excuse such records were not taken in the shade according to their method.
Secondly, they have “adjusted” their raw data for various reasons, and the adjustments have generally “cooled the past” thus increasing the apparent warming trend, and increasing the chances that a recent heat wave will produce “highest ever temperatures”.
Thirdly, neither the BOM nor their lazy media megaphones have learnt to look at the past as recorded in newspapers of the times.
Rick Dean has had such a look and his report, taken verbatim from newspapers of the times, shows that heatwaves (and associated bushfires) are nothing new. He records at least 24 heatwaves in Australia in the period 1886 to 1929. For example:
In 1895 at Bourke there were 66 deaths from heat apoplexy over a period of six weeks, during which time the heat was never under 114 degrees shade heat and, what was worse, never under 100 degrees at night. The maximum temperature recorded under true shade conditions was 128 DegF (53.3 DegC). In Sydney in Jan 1896 the temperature reached 131 DegF in the shade (55 DegC). Publications at the times recorded many earlier heat waves back to 1791.
