A paper published in Proceedings of the National Academy of Sciences (PNAS) attributes just 0.8 C/century to anthropogenic influences:
http://depts.washington.edu/amath/research/articles/Tung/journals/Tung_and_Zhou_2013_PNAS.pdf

"In fact, the net anthropogenic warming trend has been remarkably steady for the past 100 y at 0.070.08 C/decade."

That is, 0.8 C/century.

I.e., Nothing to worry about. All upside, no downside.

Here is another extract from the paper:

"If this conclusion is correct, then the following interpretation follows: The anthropogenic warming started after the mid-19th century of Industrial Revolution. After a slow start, the smoothed version of the warming trend has stayed almost constant since 1910 at 0.070.08 C/decade. Superimposed on the secular trend is a natural multidecadal oscillation of an average period of 70 y with significant amplitude of 0.30.4 C peak to peak, which can explain many historical episodes of warming and cooling and accounts for 40% of the observed warming since the mid-20th century and for 50% of the previously attributed anthropogenic warming trend (55). Be- cause this large multidecadal variability is not random, but likely recurrent based on its past behavior, it has predictive value. Not taking the AMO into account in predictions of future warming under various forcing scenarios may run the risk of over- estimating the warming for the next two to three decades, when the AMO is likely in its down phase."

I was most entertained by the article. We did have several very hot days this summer and I did wonder about the record, but I see BoM couldn't resist some fudging..

Yes, you feed the temperature data into the equation, and it tells you what the tax rate should be, while it sterilises the conclusion of any value judgment - it's "science" all the way!

you mean the carbon tax has not cooled the planet? We have been conned again. Election please and get rid of the data fiddlers. There are to many gullible who believe such nonsense.

Oh good lord!

How can there be a continent wide summer record when no part of the continent had a record?

This is like asking how can a cricket team post the highest ever innings score without one of the team scoring the individual run record.

Whew mate you are a character.

csteele; a very timely analogy with cricket given the brouhaha currently occuring with the Australian cricket team members not handing in their homework.

Are you saying all cricket players are the same or that Australian weather and climate is a cricket match?

Fascinating; who would be the opening bowlers? I would recommend QLD for pace and vigour and the ACT for spinning guile and deception. Tasmania could be the wicketkeeper given they are the per capita champions for never letting any government subsidy get through. NSW and VIc would be the opening bats as they are old stayers and can be relied upon to produce a steady effort. For anything out of the box SA can be called upon and WA will or won't turn up.

Carry on, your comments are bound to be as riveting as an ABC radio commentary.
