14th Century Climate Instability

The large number of deaths and the long cold period had the following effects:
Less agriculture that releases greenhouse gases. (less CO2)
Less cutting of trees and scrubs: more carbon is removed from air. (less CO2)
abandoned farmland acts as significant carbon sink taking CO2 from air. (less CO2)
Research show CO2 levels in atmosphere appear to fall following the black death.

Ffirst two decades in 14th century are wetter, windier and climatically more unstable.
Agriculture recovers in ~1440 Climate recovers in 16th century, stabilizing around 1640.
