Mann, Hayhoe try to erase the Medieval warm period
The MWP must have been a lot warmer than today as it allowed birches and barley to grow normally on Greenland. Try that today. They undid the barley and the birches in Greenland today. This is very simple logic and should convince everyone who sees it – except if you are part of a religious cult called Climatology. Then facts don’t matter to you. Mann and Hayhow must be tried for fraud and should do jail time.
