Tom Kurz's Misrepresentation of Climate Change in History
You don't understand Greenland temperature change. Saying that solar proxies agree with the warmer Greenland period around 1200 BC is garbage. That was a pair of grand solar minima from 1365 BC and from 1250 BC which caused the demise of the Minoans and several other civilisations. All of those civilisations flourished from around 2750 BC, when Greenland was the coldest for 3450 years.
3450 years later in the 700s AD, had the warmest Northern European summers of the Medieval Warm Period (Esper 2014), which again was the coldest in Greenland for 3450 years.
The warm spike in Greenland around 1000 AD was the Oort solar minimum:
