Keith Briffa

More Disreputable “Science” From The AGW Alarmist Crowd

Last week I pointed to the fact that the “scientist” who provided much of the basis for the AGW crowd’s alarmist appeal (as incorporated in the UN’s 2007 IPCC report) refused to provide the original data on which that model was based to peers.  He later claimed that the original data had been lost because it was unable to be transferred to newer data storage (an unmitigated crock).  IOW, peers can’t review his data and check out his theory to ensure what he’s theorizing has a valid basis in fact.  That’s a cardinal sin in real science circles.

And now, in less than a week, a second cardinal sin is uncovered.  That of cherry-picking data.  In the cross-hairs is Keith Briffa.  Steve McIntyre explains the problem:

The Briffa temperature graphs have been widely cited as evidence by the IPCC, yet it appears they were based on a very carefully selected set of data, so select, that the shape of the graph would have been totally transformed if the rest of the data had been included.

In fact, as with Phil Jones who I reported about last week, Briffa refused repeated requests for his original data (from tree rings). And it was the Briffa graphs which were used to support the contention that the “hockey stick” was valid.

When others finally got a hold of all the data and graphed it out, their findings were quite different than Briffa’s:


And, of course, when they were merged they told quite a different story than was Briffa and the IPCC:


My, what a difference using all the data makes, no?

Steve McIntyre and Anthony Watts have all the gory details, but as one commenter on Watt’s site says:

Coming just after the “lost” data from the Hadley Centre by Phil Jones, this is beginning to look more than just carelessness.

I call it the “great unraveling”. The hoax is coming unglued. And this shameful conduct will set real science back 100 years.

The question is, will the politicians see it before it is too late? Will the administration which promised that science would again take the forefront actually keep its word and ensure that happens? Methinks we’re going to find out that a political agenda and ideology are much more powerful than science. Science, quite honestly, is only useful to politicians – any politician – as long as it advances their agenda. If it doesn’t then the politician will claim it to be false science – regardless of how overwhelming the evidence is to the contrary.
