Humanity flourished during the Mediveval Warm Period, with temperatures even higher than today all over the globe - and the warming was very fast. Interestingly the graphs usually don't usually go back that far, preferring to start at the end of the Little Ice Age in the 19th century. The cause of neither is unknown/undecided, but here we are arguing that e know the cause for today's changes in weather/climate.
(Going back 6-7000 years, the Arctic Sea was totally ice-free for extended periods.)
