Crowley2000 is also mentioned in Mann's paper and has data that has been thoroughly manipulated using a simulation to remove all forcing effects except those from greenhouse gases. There's no testing of the CO2 forcing hypothesis and therefore no proof of anything.

Umm, I think that you may have gotten your papers mixed up. The one that Mann referenced is "How Warm Was the Medieval Warm Period?" by Crowley and Lowery .

The one that you found the data set on was "Causes of Climate Change Over the Past 1000 Years" by Crowley alone.

Nonetheless, it is likely that Crowley used the same data tweaking in both papers. The dataset I downloaded is tweaked and can't be used to compare current proxy measurements with past ones. I'll keep downloading data sets and posting conclusions for all the ones I download no matter what the results, but I can't draw conclusions when data has been manipulated.
