If the medieval warming happened “at all”, it WOULD have been warmer during that time than today. (or at least as warm)—It wasn’t.
Why would it have been warmer during that time that it is today?
Are you aware of the “mini ice age”?
You are showing a remarkably poor understanding of this subject.
Do you have any serious intention of discussing this subject or am I wasting my time?
Uhhhhgggghhhhh…
The contention of those who believe in medieval warming was that it was warmer then(or the same----“they were growing grapes in England”…) than now. Get it?
The mini-ice age contention is that the warming now is somehow a return to some kind of magical “normal” state. There is no evidence of this magic, because there is no normal state—only reactions to forcings–say solar forcings, etc.
You need to do some reading on the subject. You cleary don’t have any idea what you are talking about.
Reread my post, do some research and come back to me.
A typical passage regarding MWP:
“he course of action we therefore take in this endeavor is to demonstrate that approximately one thousand years ago, when the atmosphere’s CO2 concentration was approximately 25% lower than it is currently, earth’s near-surface air temperature was equally as warm as, or even warmer than, it is today, demonstrating that today’s temperatures are not unnatural and need not be due to the historical rise in the air’s CO2 content. Indeed, these and other data covering a much longer timespan suggest that a more logical cause of our present warmth is the recurrence of whatever cyclical phenomenon produced the higher temperatures of the Medieval Warm Period.”

That is based on a claim from at least 10 years ago.
Please address the elimination of the MWP because it does not fit the “hockey stick” temp curve.[/quote]
Duped again: “MWP” isn’t eliminated.
“The late 11th, late 12th, and late 14th centuries rival mean 20th century temperature levels (see Figure 3a). Our reconstruction thus supports the notion of relatively warm hemispheric conditions earlier in the millennium, while cooling following the 14th century could be viewed as the initial onset of the Little Ice Age… Considerable spatial variability is evident however [see Hughes and Diaz, 1994] and, as in in Lamb’s [1965] original concept of a Medieval Warm Epoch, there are episodes of cooler as well as warmer conditions punctuating this period. Even the warmer intervals in our reconstruction pale, however, in comparison with modern (mid-to-late 20th century) temperatures.”
