With the publication of a new paper reconstructing the earth's temperature over the last 11,300 years, we now have a deeper look into earth's history.

The view from here is startling - noting the hockey stick is replicated, and appears even more pertinent.

"...the rate of temperature rise is unprecedented since the end of the last ice age."(although the spacing of data points has been raised, the latter day spike is an extraordinary feature - especially on a graph that extends so far back)

Wondering what others think?

That's a bit naughty Poirot. Looks like cherry picking to me. One study comes out that contradicts previous studies, and you want us to hang our hats on it.

I can't access the part of the study that you quote from, but I note that we are just out of the coolest part of the holocene, and apparently 25% of the time it has been hotter.

Hard to say much more without access to the paper.

"That's a bit naughty Poirot...."

Er um....it's been all over the net for the last few days - I thought people might be interested to comment.

I'm not asking you to hang your hat on anything.

(mildly amusing that 11,300 years of data is presented in one graph - and I'm accused of a "cherry-pick"!)

It's just one graph. All the other graphs that I've seen for the period don't show anything unusual in the last 100 years. So yes, you are cherry picking.

The whole Hockey Stick fraud was based around a cherry pick. The one graph that showed a rapid uptick got adopted as the poster child of global warming, even though we now know that it depended on splicing the modern instrumental record on the paleo record when the paleo record wouldn't show what the author wanted.

Embarrasing, but the fraudster is still getting invites to academic conferences. Shows how careful you have to be in this space. It is totally corrupted.

Graham,

I'm not intending to get right into this with you.

Calling people fraudsters on your own blog is your prerogative.

I reject your assertion that I'm cherry-picking.

It's a new paper and a new graph.

Is it really so amazing that I would post on it? If I'd gone hunting way back for some obscure paper to support my view, you'd have a point. I think it's interesting and I'm interested in other views.

Impugning Michael Mann is just more of the same old same old...just one more tired cliche.

Poirot/GY I think in this world wide discussion, a fraud unequaled is in play.
But I think it is the anti climate change side that is at fault.
And that it is too late to truly change anything, the planet will warm and those that come after us will have every right to be unhappy, with us.
This country,s climate observers are telling us near weekly of the changes in our recent climate.
WHY do we ignore that.
And if not for climate change then for long term sustainability the move to clean energy is worth it surely?
America is about to move on this issue, why not us.
Poirot your task is massive, those opposing your view need no evidence just like sonofglion make claims based on pinion not science.
