Hockey sticks in the ice (cores)

Some sharp comments at this post by Neo-neocon, The WaPo goes rogue …, mentioning Sarah Palin's op-ed on Climategate. Commenter rickl suggests mailing this around: Hockey stick observed in NOAA ice core data. One of several striking graphs:

Those are years B.C. to A.D. across the bottom. Mann's hockey stick is visible on the far right. Or,
