Yes, It was Warmer Back Then

Yes, the Medieval Warm Period was warmer than the modern period and it was global (and probably bounced around about as much as modern climate, despite being warmer. )
A peer-reviewed study documents the extremely warm temperatures of the Medieval Period that occurred in the California Sierra Nevada range. Scientists, working with dead tree trunks located above the current treeline, affirm California’s Medieval extreme warm temperature history, which still remains unprecedented.
The ideal, of course, would be for the world to be a couple of degrees warmer, for CO2 levels to be significantly higher, and for market forces to cause Mr. Gore’s” investments” to decline greatly in value.
