IPCC AR6 SPM Credibility Destroyed by “Disappearing” Medieval Warming Period

I know, they don’t like the MWP very much. But if you are a hobby historian as I am, you most certainly not only know about the MWP but also the roman Warm Period and some others before that one. Yes, they came without any increase in CO2 and were much warmer than we have today. How do we know? people 2000 years ago did not do agriculture for fun. They planted what worked best as often, their lives depended on it. Mis-harvest and you might starve. And looking at the red wine harvest from Britain almost 2000 years ago I know it was warmer than today.
