QFTD: … Climatology is now infected by partisan polemics,

February 13, 2017 § Leave a comment

Climatology is now infected by partisan polemics, but ice‐core studies that show rising carbon dioxide levels in the atmosphere over the last 10,000 years are undisputed. According to an ‘anthropogenic’ explanation offered by an eminent climatologist with much persuasive evidence, agricultural deforestation, which replaces natural greenery with bare planted fields and increasing livestock herds, especially methane‐producing cattle, has measurably contributed to rising levels of carbon dioxide over the last several thousand years. In any case, carbon dioxide levels in the ice show two abrupt and drastic declines, one of which correlates with c.541, providing independent evidence of an unprecedented demographic collapse, which would have caused the widespread reversion of cleared fields to natural greenery, and the predation of abandoned cattle—imperial territories still had populations of wolves, bears, lions, and cheetahs, and also Caspian tigers in eastern Anatolia. The climatological evidence is more decisive than the archaeological evidence, but the latter is perfectly consistent. A recent overview concludes: ‘the expansion of settlement that had characterized much of rural and urban Syria in the fifth and early sixth centuries came to an abrupt end after the middle of the sixth century. There is evidence that housing starts almost ceased.’
