How much can we rely on data adjustments by people convinced the evidence should show a warming?
Researcher Jennifer Marohasy ... has analysed the raw data from dozens of locations across Australia and matched it against the new data used by BOM showing that temperatures were progressively warming.
In many cases, Dr Marohasy said, temperature trends had changed from slight cooling to dramatic warming over 100 years.
BOM has rejected Dr Marohasy’s claims and said the agency had used world’s best practice and a peer reviewed process to modify the physical temperature records that had been recorded at weather stations across the country.
It said data from a selection of weather stations underwent a process known as “homogenisation” to correct for anomalies.
US measured temperature data (blue below) shows that we have been cooling for nearly a century. But the temperatures reported by NCDC (red below) show the opposite, that the US is warming…
They accomplish this transition by an impressive 1.6 degrees of data tampering, which cools the past and warms the present.
is that story from another Murdoch paper? 
winter was apparently 2 degees warmer this year in Melb. according channel 9's weather report last night
Bom admit to their practices......
It's interesting that you declare their transparency as a conspiracy theory......lol.

obviously channel 9 is owned and run by communist socialist pinko lefty types, what an outrage, someone should let uncle rupes know - then the bolter and jones could run smear campaigns against channel 9 for being not on Team Australia.
