Australian Met Office accused of man-made climate change (again) 

This approach to data seems par for the course in climatology, as they strive ever more to make the world look warmer than before, in order to prop up the failing theory of human-caused trace gases ruining the world.

The Bureau of Meteorology has rewritten Australia’s temperature records for the second time in six years, greatly increasing the rate of warming since 1910 in its controversial homogenised data set, writes Graham Lloyd in The Australian.

Rather than the nation’s temperature having increased by 1C over the past century, the ­bureau’s updated homogenised data set, known as ACORN-SAT, now shows mean temperatures have risen by 1.23C.

Bureau data shows the rate of mean warming since 1960 has risen to 0.2C a decade, putting the more ambitious IPCC target of limiting future warming to 1.5C close to being broken.

Homogenisation of temperature records is considered necessary to account for changes in instrumentation, changes in site locations and changes in the time at which temperatures were taken.

But the bureau’s treatment of historical data has been controversial. In recent years there have been claims that the organisation was treating temperature records in such a way that left it exposed to accusations that ideological pursuits had trumped good scientific practice.
