Heres where we disagree.
If you're right and all of them have overlooked it, you'll have material for a hell of a paper yourself: There's nothing more juicy than a paper that mathematically proves that a pile of accepted scientific literature is flawed.
Imagining possible flaws of a paper before reading it is so easy that it's hard to really strike gold (it is equally easy for the authors and reviewers). But it is also an enjoyable way to learn how those flaws have been taken care of.
And lets not pretend one or two papers that make bold claims hold much water.
I've been misled by popular media many times, so color me unsurprised that they might be selling some bullshit about this as well. (Not that they certainly are.)
The AGW papers I've read, though, are very solid, and more sophisticated than I expected.
