Since a commenter mentioned the medieval vineyards in England, I've been engaged on a quixotic quest to discover the truth about the oft - cited, but seldom thought through, claim that the existence of said vineyards a thousand years ago implies that a «Medieval Warm Period «was obviously warmer than the current climate (and by implication that human - caused global warming is not occuring).

So, given that man's activities probably does have some influence (i.e.: magnitude and duration) of the current warming period I'm guessing we'll probably continue to warm for another 400 years or so.

In so far as M&M are trying to distort the climate data over the last 1000 years to show that the so - called «Medieval Warm Period» replicates or exceeds the current warming — and so natural variability could possibly account for that warming — I thought it worthwhile to put out some information about Medieval climate.

Japanese Naval Records indicate a fleet navigated a completely ice - free Arctic Ocean at the peak of the Medieval Warm Period, so total melting is nothing new, however unlikely at current temperatures.

If there was more natural variation in the past millenia, specifically due to solar changes, then that goes at the cost of the GHG / aerosol combination, as both are near impossible to distinguish from each other in the warming of the last halve century... Solar activity has never been as high, and for an as long period, as current in the past millenium (and even the past 8,000 years).

It would be foolish to «rule out» solar forcing completely, as certain correlations between solar variation and climate have certainly been observed in the past, and the current warm period has coincided with high solar activity.
