… History and the Limits of the Climate Consensus | The American Conservative.

The 2015 Paris Conference declared a target of restricting “the increase in the global average temperature to well below 2 degrees C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 degrees C above pre-industrial levels.” It’s very important to set a baseline for such efforts, certainly, but what on earth is intended here? Which pre-industrial levels are we talking about? The levels of AD 900, of 1150, of 1350, of 1680, of 1740? All those eras were assuredly pre-industrial, but the levels were significantly different in each of those years. Do they want us to return to the temperatures of the Little Ice Age, and even of the depths of cold in the 1680s? The Winter of 1684, for instance, still remains the worst recorded in England, ever. Or are the bureaucrats aiming to get us back to the warmer medieval period, around 1150?
