"You're a really dedicated follower." I had to pass college physics. We covered the Greenhouse Effect, as it was called back then. I'd say the biggest purveyor of bullshit on the entire planet is Matt Drudge, followed by Faux. Rush is close on their tales (sic), while Anthony Watts is slightly ahead of Steven Goddard in the JV climate-deniers division. Mann, however, has seen his study replicated by about 23 studies. here's an additional one Continental-scale temperature variability during the past two millennia nature.com The 2K Network has just published a major paper in Nature Geoscience ( abstract and figures here), with 78 researchers contributing as co-authors from 60 separate scientific institutions around the world. The analysis combines records from tree rings, pollen, corals, lake and marine sediments, ice cores, stalagmites and historical documents from 511 locations across seven continental-scale regions to reconstruct past global surface temperature changes over the past 2,000 years. Their two main results are a confirmation that current global surface temperatures are hotter than at any time in the past 1,400 years (the general 'hockey stick' shape, as shown in Figure 1), and that while the Medieval Warm Period (MWP) and Little Ice Age (LIA) are clearly visible events in their reconstruction, they were not globally synchronized events. Figure 1: a) Previously published Northern Hemisphere 30-year-mean temperature reconstructions relative to the 1961–1990 reference period. b) Standardized 30-year-mean temperatures averaged across all seven continental-scale regions. Blue symbols are area-weighted averages, and bars show 25th and 75th unweighted percentiles to illustrate the variability among regions; open black boxes are unweighted medians. The red line is the 30-year-average annual global temperature from the HadCRUT4 instrumental time series relative to 1961–1990, and scaled visually to match the standardized values over the instrumental period.
