Note in the Graph below 2 of 3 reconstructions that go back to 900 AD say it was warmer back in the MWP than it is now.
[Which I cleaned from the bottom image. ]
So Esper et al and Moberg et al have evidence of the MWP in the image below, then there's:
the Viking farms now in permafrost
The crops in Europe that can't be grown where they could 1000 yrs ago because it's too cold now.
Lastly [for now] I submit the elephant seal breeding grounds of Antarctica that were warmer 1000 yrs ago.
Good lefties will pay attention to none of that.
So I would say there is evidence of a global phenomenon called the MWP there is evidence on the ground as well as proxy evidence that it was warmer about a thousand years ago then now. I have to thank blogger scruffyDan who I would link to if he wasn't such a troll, still
I should thank him for pointing out the Esper et al and Moberg et al studies which for some reason the National academy of sciences doesn't talk about they blather on about Mann so much because, well they are cherry picking.
You may wonder who the dissenter is with the red line below the only one to go to the MWP and shows it warmer now, that was by Mann home of the poor data handling and obsolete proxy records hockey stick ignored in the latest IPCC release.
The graph this was created from here below.
