Fielding gets no answer

Herald Sun, June 16, 09
Steve Fielding confronts Climate Minister Penny Wong with his question: why has the world not warmed these past seven eight years when we’re pumping out more carbon dioxide than ever?
AUSTRALIA’S top scientists have met Family First senator Steve Fielding to try and convince him that climate change is real… It was a case of duelling scientists at the high-level meeting in Canberra today. Senator Fielding took along a team of sceptical scientists.
In Climate Change Minister Penny Wong’s corner were Australia’s chief scientist, Penny Sackett, and eminent climate scientist Will Steffen.
“Global warming quite clearly over the last decade hasn’t been actually occurring,” Senator Fielding said before the meeting… He took charts into today’s meeting to show that global temperatures had not increased since 1998…
Prof Steffen emerged from the 90-minute meeting to say that global warming was real. While 1998 was a particularly hot year, the decade since had remained warmer than average.
“The climate’s still pretty warm,” the Australian National University academic said….
A spokesman for Senator Fielding said the evidence put forward by his team had given Senator Wong food for thought. The Senator felt his key questions had not been answered in the meeting, but he was going to spend some time thinking it over.
It sounds indeed as if Fielding got no answer to his very interesting question.
Lucia’s The Blackboard tracks global temperatures since 2001, as measured against predictions of a warming of 2 degrees this century (brown line):
Conclusion? Global temperatures have fallen over the past eight years, despite increases in our emissions:
The trends for both UAH and RSS are negative since 2001 with RSS having the larger negative trend.
But Lucia notes that over a longer term, the temperature trend has gone slightly up, rather than down, and hazards this guess:
For what it’s worth: My bet is on the longer term trend being positive. Why? The past longer term trend was positive. I’m inclined to believe the longer term trend will be less than 2C/century. Why? The current data says it’s less than 2C/century and the longer term trend is less than 2C/century. Other than models, there is no evidence the climate trend has increased from historic levels to reach a rate of 2C/century.
This does not indicate any runaway warming, devastating warming or necessarily even man-made warming. And only time will tell if the world will actually resume warming.
Lucia notes that a third of the world’s main four measurements of global temperature confirms cooling since 2001.
Now the “proof” given by Penny Wong’s advisors is not the atmospheric temperatures they’ve used for so long, but the sea:
STEVE FIELDING: Now up until now, we have seen carbon emissions go up and global temperatures, the way the IPCC has been measuring them, not going up.Now if that is the case that is a real problem.Now yesterday, yesterday’s meeting with the chief scientist and Professor Steffen, they outlined that they are using a different temperature measure which is ocean temperature. Now that is something we are going to have to look at because that is something that the IPCC wasn’t using to prove that carbon emissions were driving up global temperatures.Previously they were using something from the Hadley Institute or the Hadley Centre and the University of East Anglia. That is the measurement that I have been given and it quite clearly shows that carbon emissions have been going up but global temperatures haven’t.Now yesterday they showed another figure which is ocean temperature.
So let’s now look at ocean temperatures, as plotted by Dr Craig Loehle in Energy & Environment from the profiling floats of the 3000 Argo buoys. A gradual rise in temperature ended – or paused – six years ago:
Ocean heat content data from 2003 to 2008 (4.5 years) were evaluated for trend. A trend plus periodic (annual cycle) model fit with R2 = 0.85. The linear component of the model showed a trend of -0.35 (~0.2) x 1022 Joules per year. The result is consistent with other data showing a lack of warming over the past few years
This confirms what Roger Pielke snr had noted.
What else they got?
