HI Andy,

Yep, what was written below is all me, but it was purely on background, please don't quote

anything I said or attribute to me w/out checking specifically--thanks.

Re, your point at the end--you've taken the words out of my mouth. Skepticism is essential

for the functioning of science. It yields an erratic path towards eventual truth. But

legitimate scientific skepticism is exercised through formal scientific circles, in

particular the peer review process. A necessary though not in general sufficient condition

for taking a scientific criticism seriously is that it has passed through the legitimate

scientific peer review process. those such as McIntyre who operate almost entirely outside

of this system are not to be trusted.

thanks heaps.

tom crowley has sent me a direct challenge to mcintyre to start contributing to the

reviewed lit or shut up. i'm going to post that soon.

just want to be sure that what is spliced below is from YOU ... a little unclear . ?

I'm copying this to Tim, in hopes that he can shed light on the specific data assertions

made over at climateaudit.org.....

I'm going to blog on this as it relates to the value of the peer review process and not on

the merits of the mcintyre et al attacks.

peer review, for all its imperfections, is where the herky-jerky process of knowledge

building happens, would you agree?

p.s. Tim Osborn ([1]t.osborn@xxxxxxxxx.xxx) is probably the best person to contact for

further details, in Keith's absence,

Hi Andy,

I'm fairly certain Keith is out of contact right now recovering from an operation, and

is not in a position to respond to these attacks. However, the preliminary information I

have from others familiar with these data is that the attacks are bogus.

It is unclear that this particular series was used in any of our reconstructions (some

of the underlying chronologies may be the same, but I'm fairly certain the versions of

these data we have used are based on a different composite and standardization method),

let alone any of the dozen other reconstructions of Northern Hemisphere mean temperature

shown in the most recent IPCC report, which come to the conclusion that recent warming

is anomalous in a long-term context.

So, even if there were a problem w/ these data, it wouldn't matter as far as the key

conclusions regarding past warmth are concerned. But I don't think there is any problem

with these data, rather it appears that McIntyre has greatly distorted the actual

information content of these data. It will take folks a few days to get to the bottom of

this, in Keith's absence.

if McIntyre had a legitimate point, he would submit a comment to the journal in

question. of course, the last time he tried that (w/ our '98 article in Nature), his

comment was rejected. For all of the noise and bluster about the Steig et al Antarctic

warming, its now nearing a year and nothing has been submitted. So more likely he won't

submit for peer-reviewed scrutiny, or if it does get his criticism "published" it will

be in the discredited contrarian home journal "Energy and Environment". I'm sure you

are aware that McIntyre and his ilk realize they no longer need to get their crap

published in legitimate journals. All they have to do is put it up on their blog, and

the contrarian noise machine kicks into gear, pretty soon Druge, Rush Limbaugh, Glenn

Beck and their ilk (in this case, The Telegraph were already on it this morning) are

parroting the claims. And based on what? some guy w/ no credentials, dubious connections

with the energy industry, and who hasn't submitted his claims to the scrutiny of peer

review.

Fortunately, the prestige press doesn't fall for this sort of stuff, right?

mike

I'm sure you're aware that you will dozens of bogus, manufactured distortions of the

science in the weeks leading up to the vote on cap & trade in the U.S. senate. This is

no

needless to say, seems the 2008 pnas paper showing that without tree rings still solid

picture of unusual recent warmth, but McIntyre is getting wide play for his statements

about Yamal data-set selectivity.

Has he communicated directly to you on this and/or is there any indication he's seeking

journal publication for his deconstruct?

Mass Migrations And War: Dire Climate Scenario

Mass migrations and war: Dire climate scenario

CHARLES J. HANLEY, AP Special Correspondent – Feb 21, 3:00 pm ET

CAPE TOWN, South Africa – If we don't deal with climate change decisively, "what we're talking about then is extended world war," the eminent economist said.

His audience Saturday, small and elite, had been stranded here by bad weather and were talking climate. They couldn't do much about the one, but the other was squarely in their hands.

And so, Lord Nicholas Stern was telling them, was the potential for mass migrations setting off mass conflict.

"Somehow we have to explain to people just how worrying that is," the British economic thinker said.

Stern, author of a major British government report detailing the cost of climate change, was one of a select group of two dozen — environment ministers, climate negotiators and experts from 16 nations — scheduled to fly to Antarctica to learn firsthand how global warming might melt its ice into the sea, raising ocean levels worldwide.
