Yeah, I know its hard to admit that has been discredited.
I've posted lots of peer-reviewed studies showing the MWP was warmer than the current century - here:

CRU scientist Keith Briffa ... emailed Edward Cook of Columbia University: “I am sick to death of Mann stating his reconstruction represents the tropical area just because it contains a few (poorly temperature representative) tropical series,” adding that he was tired of “the increasing trend of self-opinionated verbiage [Mann] has produced over the last few years .??.??. and (better say no more).”
Cook replied: “I agree with you. We both know the probable flaws in Mike’s recon[struction], particularly as it relates to the tropical stuff. ...”
In yet another revealing email, Cook told Briffa: “Of course [Bradley] and other members of the MBH [Mann, Bradley, Hughes] camp have a fundamental dislike for the very concept of the MWP, so I tend to view their evaluations as starting out from a somewhat biased perspective...”
.....
Even Malcolm Hughes, one of the original hockey stick coauthors, privately expressed reservations about overreliance on their invention, writing to Cook, Mann and others in 2002:
All of our attempts, so far, to estimate hemisphere-scale temperatures for the period around 1000 years ago are based on far fewer data than any of us would like. None of the datasets used so far has anything like the geographical distribution that experience with recent centuries indicates we need, and no one has yet found a convincing way of validating the lower-frequency components of them against independent data....
Mann didn’t react well to these hesitations from his colleagues. Even Ray Bradley, a coauthor of the hockey stick article, felt compelled to send a message to Briffa after one of Mann’s self-serving emails with the single line: “Excuse me while I puke.”
