See reply 63 for your edification.
As I said, "the globalwarmingwhackos have steadfastly maintained that the Medieval Warming was not world wide is that the Science showing the warming there is Absolutely Irrefutable. When someone devises an equally good way of establishing that it was, in fact, worldwide, they'll figure out some other way to lie and obfuscate to their moronic target masses. I've yet to hear any of their vaunted "models" demonstrate any possible methodology for maintaining a warm Arctic for centuries without other major climactic ramifications, but their "faith" allows them to simply 'know' that earth is warmer now than ever before - because man's activities 'clearly' makes it that way."
Keep up your faith mission.
