Slightly agree, start and end points are selected in lots of circumstances from Climate to Corporate Results to show the message that who is doing the selecting wishes to show. Skeptics are just as guilty of cherry picking as non-skeptics.

Yep - greater extremes than now were in play.

It was amusing because they didn't even predict the snow but made a huge anouncement about how robust their models were on the way to the airport. They still collected their performance bonuses that year though so I suppose they had the last laugh.

Wrong. If it was as simple as that the models predicting temperature would be spot on which they aren't. Also

Ignore it, and it won't happen.
You misunderstand my motives - 1) credibility in the science needs to be rebuilt after some bad episodes. Maybe you don't agree but for example CAGW was not mentioned in the US election and the UK government tries to avoid mentioning it at all. Also 2) it would be useful to know what prevention / mitigation steps may be needed, what will work and what will work best. And 3) the models could be improved

In theory yes, but in practice the proxy approach is more complicated. The famous "mike's nature trick to hide the decline" quote relates to this.

Prof. Mann has never released all of the code citing IPR, and has withheld quite a lot of the data - so it remains a black box. I've just been lent a copy of his recent book on Friday which I haven't started yet - it will be interesting to see how it matches other accounts already out there.

Again given all of the code and data hasn't been released, how do we know ? Maybe Open Source it ?

Would that be a reference to Professor Muller who thinks other climate scientists were "guilty of fraud" and Al Gore is a "science denier" ? No really he did say that - listen here.

Agree though - "sides" is the wrong word, too combative.
