Was the hockey stick basically correct?

The hockey stick was not correct. The big deal is that it suppressed the MWP which demonstrates a higher temperature without human CO2 emissions. Mann's methodology produces a hockey stick even with random numbers: a href="http://landshape.org/enm/a-new-temperature-reconstruction/" rel="nofollow"http://landshape.org/enm/a-new-temperatu…/a Further, the blade of the stick just happens to occur when he and his co-authors started using thermometers instead of tree ring proxy data.
