'We are living in a comparably cold time today. During MWP 1000 years ago, it was 1°C warmer than today. During Roman Optimum 2000 years ago, when Hannibal crossed Alps with his elephants in wintertime, it was even 2°C warmer than today. And during Holocene climate optimum 3500 years ago it was about 3°C warmer than today. Since about 3200 years ago, there has been a cooling of about 2°C.'
