the medieval warm period did not occur with nearly the same speed as our current warming, we're seeing temperature shifts larger in single years than what they saw in decades

Yawn. Nothing I haven't heard before. Funny how your 200 year mark lands perfectly with the end of the medieval ice age. Temperatures are less than 1°C above the norm for the past 1000+ years. That kind of move, even within a couple hundred years, is pretty insignificant and common in a geologic time frame. Do you know the most potent greenhouse gas is?
