What an interesting choice of words for dipassionate and ostensibly disinterested meteorologists.
The observed data confirms something? I would have thought the observed data simply was the observed data.
The BOM appears to have started with an hypothesis to confirm, so it's worth checking on their sums to make sure that confirmation-bias hasn't influenced the result. Because of the potential conflict of interest between the political interests served by a warming finding and that political nexus to funding, then I think some heavy duty diligence on the formulas, weightings, averaging methods and assumptions in the BOM's number crunching is a useful investment.
Here's the first couple of lines of the Bureau of Meteorology's statement last Friday.
2013 confirmed as Australia's hottest year on record
Today's release of the Bureau of Meteorology Annual Climate Statement 2013 confirms Australia has recorded its hottest calendar year on record.
Our reader Samuel Gordon Stewart has run the temperature data and produced a result that confirms something quite different.
I don't know Samuel but he has presented his credentials at his website and his workings and spreadsheet are attached to be given the once-over by all and sundry. Good on him!
I recorded this editorial broadcast by 2UE and the follow up interview with Dr David Evans on 4 May 2011. I found it useful to listen again. It's very hard for a person to hold a belief when his income is dependent on it not being so.
