wrong again, this time about Michael Mann
You said Mann denies many/most parts of the northern hemisphere grew colder in the LIA.
"Moreover, the cooling that resulted was confined mainly to the northern hemisphere, says Lynch-Stieglitz - which indicates it was a regional effect. Michael Mann at Pennsylvania State University in University Park, who constructed the hockey stick graph, has always argued that if this were so, the little ice age would not show up on a global temperature record (New Scientist, 18 March, p 40)."

I'll just add that one to your assumption about grapes not being grown in England.
