re I think I saw somewhere that the spread of Black Death was influenced by climate disruption, possibly a cold period. I'm not quite sure what the connection is most communities were ag based.. forests had been cleared and burned as fuel.. and planting areas expanded.. to feed the increasing populations .. World wide.... the clearing and burning of these forests Released the CO2 in the wood additionally.. wet land farming in Asia..
