Australia’s Bureau of Meteorology (BOM) has been caught red handed erasing record-breaking cold temperatures from its data records.
The BOM has now been shamed by media investigations into ordering a review of its procedures. But it has yet to provide an explanation as to why it made these “adjustments” in the first place.
These “adjustments” seem to go only one way. The BOM is perfectly happy to record and announce it whenever Australia’s temperatures hit record-breaking highs. But when the temperatures reach new lows it’s a different matter altogether.
For some strange reason that the BOM has been unable to explain, when temperatures go below a certain point it either deletes them as if they had never been – or it enters them into its records at higher temperature than the one actually recorded by its thermometers.
The dodgy adjustments were spotted by investigative journalist Jennifer Marohasy.
Earlier this month, she was contacted by bush meteorologist Lance Pidgeon who had noticed that Goulburn, a town south west of Sydney, had smashed its temperature record with a low of -10.4 degrees Celsius.
Except, the Bureau has since erased this measurement.
According to the Bureau’s own rules, the coldest temperature record during a 24-hour period to 9am is recorded as the minimum for that day. So, for Sunday 2 July the carry-over minimum should be -10.4 degrees Celsius. But instead the summary documentation shows -10.0. There is now no public record of -10.4 degrees Celsius.
This is not the first time the BOM has been accused of behaving more like a political activist organization than a scientific one. On every occasion, instead of fessing up to its dodgy antics, it has hidden behind a wall of bluster and pretend-scientific authority.
For example, against the principles of robust science, it refuses to allow its data to be audited independently – or to discuss why or how it makes its temperature adjustments.
