It's well studied, but not well studied. Climatology is essentially a branch of history and suffers the same issues with low quality sources that can't be upgraded via experiment because they're recordings of past events, ideological bias amongst practitioners and other issues.

Well you have the opportunity to make an argument. But I've personally worked with the data. So your going to need more then a "trust me bro" to convince me or many others.

See my comments on PAGES2K on another thread, reachable from my profile link. But as you've worked with the data presumably nothing in those posts is news to you, and you're well aware of the sorry state of paleoclimatology.
