Not the Medieval Warm Period

 

The history displays in Kentmere church are awesome. I was interested in two things here. The first is the error range in the radiocarbon dating. That should mean the absolute error is +-150 years to give a range of 300 years but sometimes usage slips. The second is Medieval Warm Period. I know nothing about this so looked it up here. It's the period that Greenland was colonised by Vikings. And as it is said to start in 950, that means the +-150 years reading must be correct.
