Meanwhile, I suspect you've both seen the latest attack against his Yamal work by McIntyre. Gavin and I (having consulted also w/ Malcolm) are wondering what to make of this, and what sort of response---if any---is necessary and appropriate. So far, we've simply deleted all of the attempts by McIntyre and his minions to draw attention to this at RealClimate.
Flashback: Michael "robust debate" Mann on the opportunity to robustly debate Steve McIntyre: "Phil, I would immediately delete anything you receive from this fraud...I would NOT RESPOND to this guy. As you know, only bad things can come of that"
[Mann] Good editorial on #CRUHack2 in The Economist: emails actually show science working as it should (robust debate, etc.)
