The Medieval Warm Period was regional, with some regions warm and other regions cool. Globally, the Medieval Warm Period was cooler than now.

I doubt that there is sufficient evidence to support this bald contention. The above statement applies to present climate as well: some regions warm and other regions cool. that's the way climate works.

You "doubt it," even though the links provided above are excellent evidence showing exactly that.

Actually, no. Mann's Hockey Stick has been thoroughly discredited because it mixes proxy data sets in inappropriate ways, leading to erroneous conclusions.

MBH 1999 has NOT been discredited. The literature is filled with hockey stick graphs because that is what CO2 and temperature have done.

What happened in the MWP is irrelevant. The MWP was not caused by human CO2 emissions and did not threat human infrastructure. Current warming was and does.
