There’s good stuff on this topic at one climate blog I frequent called the Blackboard. Just read a blog post there dealing with a withering critique of a paper by a German climate “scientist”; this paper was used by IPCC chairman (Indian guy, can’t remember his name), Gore and others recently to claim that current temperature trends are actually worse than models predicted. Contrary to the actual temperature trends which are flat or negative.

Turns out the German was using an end point filter which requires guessed future values on the temperature data that he “tweaked” to get this result. He changed the smoothing parameter from an earlier paper, because otherwise he wouldn’t get the “right” answer. And this was published in Science no less! Peer “reviewed” and all.
Absolutley disgusting what has happened to “science” in this case.

But i should really go back to originals of Popper and read it as opposed to Monarch notes versions on the web in Wikipedia and such.
