&lt;blockquote&gt;Bishop, I am surprised you would even bother to link that tripe here (except for educational purposes of what NOT to do). It consists entirely of distortions, lies, and ad hom attacks and serves no useful purpose in furthering dialogue.&lt;/blockquote&gt;


 The usefulness of linking to tripe like that is not in the realm of furthering scientific dialogue.
It does have a use however in reminding people of the second tier attacks on valid criticisms.
Mann, Schmidt, Briffa etal respond fairly testily all too often but preserve some level of professionalism. Unfortunately they also give a pat on the head to places like Deep Climate (or a Tamino, who slides back  and forth from official RC posts to his own site for ad homs) and rely on them for just the kind of cheerleading and ad homs that set up a meme to discredit SteveM and others&#039; arguments that Gavin, Mann, Briffa and others can&#039;t discredit with the numbers.]]></description>

Yes, of course it was noticed. Steve cherry picked nothing. He noted a divergence between the two series and asked &quot;why combine them this way, and not some other?&quot; &quot;Why substitute Yamal for Polar Urals?&quot; They are still going with the strawman fabrication that Steve concocted an alternative chronology. He noted an anomaly and asked for the criteria used to decide (1) how to aggregate sites into a regional chronology, and (2) how to screen out chronologies, such as Polar Urals, as &quot;unsuitable&quot;. And for this - pointing out what really IS a disturbing pattern (arbitrary choices with a lack of disclosure on screening methodology) - he is demonized.]]></description>

		<description><![CDATA[Did you guys notice the implication that Steve was cherry-picking by selecting Schweingruber&#039;s Khadtya site instead of the other sites in the area.  Suspicious indeed.  Avam was 400 km away, so clearly Steve should have included every site within that distance.  The authors would have been perfectly OK with that.]]></description>

		<description><![CDATA[Re: &lt;a href=&quot;#comment-363992&quot; rel=&quot;nofollow&quot;&gt;steven mosher (#116)&lt;/a&gt;,
The variances (and means) are very low in the early parts of those few series. Up to the 1890s. So the rings appear &quot;complacent&quot;, or slack, with low covariance and hence low correlation. Note the absence of any large-sigma anomalies. Later on in those series you have large-sigma spikes which are the basis for high correlations. (Frankly, I have a very hard time believing those spikes are related to synchronized climate anolamies. Yet they appear to be the basis for crossdating.)]]></description>
