geoff, just looking at the graph in your article global temperature relative to peak holocene temperature, it just looks like there are peaks every 100 000 years, interested in your views.

Another alarmist rant from a left of left wing perspective.

Hi Geoff , thanks for your advice , I filed it with the MIA Farmers advice eg; "The Darling River is finished as a River".

There are sceptical climate scientists, there are climate scientists who believe in AGW, and then there is James 'Death Trains' Hansen, who stands only slightly below Al Gore in the Apocalyptic Self-Promotion stakes.

But enough ad hominem: I notice that your article has several charts showing claimed temperature levels over time, but none showing sea levels over time. Just an oversight? Or is this because they would reveal that the rate of increase in sea levels with temperature rises -- if there are temperature rises -- is far too slow to worry the human race? Just how fast DID sea levels rise during the Pliocene, anyway, and how do you know?

If and when your 'exponential' process ever speeds up to dangerous levels we will all be safely dead, so why panic? I prescribe a deep breath, a dose of http://tinyurl.com/46o7g4j and a good lie down. And next time Hansen calls, don't answer.

How darreeee you skeptics question the entirely reasonable assertion of AGW.. agast!

(pssst..maurice...have you sorted General Otega for his soon to come 'climate debt' bonanza ? tell him to make sure he's opened his Swiss bank account in time, and don't forget the 'gift' to the Democrats once it comes through)

Why....GLOBAL WARMING is absolutely caused by our rampaging exploitation of the planet..and the RICH nations owe PLENTY to the poor nations.. ooops..wait.. sorry..that's on the 'Wealth Redistribution' agenda.. must have got my notes mixed up ....*red face*

Back to the point..... Yes.. AGW.. we have the science.. we have the data (Psst Dave.. did you tell our mates in mainstream media to supress that story about wrongly calibrated data collection sensors?.. you did ? great! keep the boys at CCX informed ok!)

It's a done deal.. when cap and TRADE laws come in... we can take truckloads of dosh of the capitalist pig nations and spread it among our human rights commissions in 3rd world countries... Oops... more wrongly assembled notes/talking points.. damn!

Geoff

go back and look at your own article. To my reading both the deep ocean sentiments and the ice core data agree that there were several episodes in the climate record where temperatures were higher than now.

However, Hanson et al say that if the figures are adjusted in this clever if rather obscure way then those irritating peaks are eliminated and, really, present temperatues are higher.

Silly us for not seeing this before.

Apart from these arguements being transparently ad hoc, Geoff, the paper simply draws attention to the fact that two different sets of fossil record say clearly that temperatures have been higher in pre-industrial times. I wasn't aware of the deep sea sediment record until just now.

It would have been better for your side not to say anything at all.
