> notwithstanding Mann's dubious practices
But that is just it. Mann is the elephant in the room, you simply can not ignore him. He was so obviously a fraud, and stone cold busted, and not a single voice was raised against him by the warmers. That is called a clue. What more do you want, the hand of God to reach down to you with a graven stone tablet saying "AGW IS A FRAUD!" or something? They didn't care if the science was fake because they aren't interested in the least in science. They have a policy solution in mind and the science will be tortured until it confesses.
AGW may indeed be real. But it is literally impossible to say at this point. The raw data was destroyed and the 'adjusted' data we have left is unreliable. Not only that we would need a lot more data for a lot longer than reliable records have been kept to say with the reliability normally expected from science. We do know the Earth has been both a lot warmer and a lot colder than at any point in the last hundred years. We are making predictions on time horizons as long as our reliable data set of past history and covering that lack with a lot of proxy data of dubious reliability. Doesn't sound very scientific if ya ask me, but I'm just a lay person. But somehow I doubt anyone would build a multibillion dollar chip fab on a theory of such reliability yet we are supposed to entirely reorder our economy on this theory's predictions. And anyone who expresses a doubt is called an idiot, anti-science and worse.
