Of course the temperature measurements went down after the measuring process was adjusted to report the raw data.
The Australian reports.
Recorded temperatures at the Bureau of Meteorology’s Thredbo Top automatic weather station have dropped below -10C in the past week, after action was taken to make the facility “fit for purpose”.
A record of the Thredbo Top station for 3am on Wednesday shows a temperature reading of -10.6C. This compares with the BoM’s monthly highlights for June and July, both showing a low of -9.6C.
The BoM said it had taken immediate action to replace the Thredbo station after concerns were raised that very low temperatures were not making it onto the official record. Controversy has dogged the bureau’s automatic weather station network since Goulburn man Lance Pigeon saw a -10.4C reading on the BoM’s website on July 2 automatically adjust to -10C, then disappear.
Later independent monitoring of the Thredbo Top station by scientist Jennifer Marohasy showed a recording of -10.6C vanish from the record.
BoM initially claimed the adjustments were part of its quality control procedures. But bureau chief executive Andrew Johnson later told Environment Minister Josh Frydenberg that investigations had found a number of cold-weather stations were not “fit for purpose” and would be replaced.
Several other temperature measurement stations are also receiving the fix to stop adjusting the raw data:
An in-house investigation that includes two independent experts has been called. The bureau said it rejected allegations aired in some media outlets that it had sought to tamper with temperature data.
It has been reported online that electronic smart cards were allegedly fitted to the BoM’s automatic weather stations, which put a limit on how low temperatures could be recorded in official weather data. The BoM declined to comment ahead of the internal review.
[…]On her website yesterday, Dr Marohasy said it was not the recording devices that were at fault. “To be clear, the problem is not with the equipment; all that needs to be done is for the smart-card readers to be removed,” Dr Marohasy said.
And this was not a situation where the government, which had been lying, corrected itself. Oh no! Challenges to the faked government data came from outside the government, as Bureau of Meteorology minister explained:
“The first we heard of the problem was in early July after (The Australian) approached the Bureau of Meteorology,” the minister said.
You might remember a recent scandal where it was discovered that scientists in the UK had been adjusting the temperatures to “hide the decline” of temperatures in their simulation code.
Here was the data before hiding the decline:
And here was the data after:
That second graph, with “Mike’s Nature trick” to “hide the decline” was sent then to the IPCC to influence climate policy. I have no doubt that socialist governments were very grateful for this “evidence”. Just what they needed to get a mandate from the masses to control businesses and consumer spending were grateful for this hiding of the decline, and rewarded the scientists with many research grants. This is why we call global warming alarmists “watermelons”: green on the outside, and red on the inside.
If you’ve never heard of that Climategate story from 2009 before, you should definitely read about it. Here is a good single post that explains what happened.
