And if climate Cassandras are as conscientious as they claim to be about weighing evidence, how do they accommodate historical evidence of enormously consequential episodes of climate change not produced by human activity?…. In the Medieval Warm Period (MWP), from the end of the ninth century to the beginning of the 14th, the Northern Hemisphere was warmer than at any time in the last 8,000 years

for reasons concerning which there is no consensus…. Then, near the end of the MWP, came the severe winters of 1309-1312, when polar bears could walk from Greenland to Iceland on pack ice. In 1315 there was rain for perhaps 155 consecutive days, washing away topsoil. Upwards of half the arable land in much of Europe was gone; cannibalism arrived as parents ate children. Corpses hanging from gallows were devoured…. Human behavior did not cause this climate change. Instead, climate warming caused behavioral change (10 million mouths to feed became 30 million). Then climate cooling caused social changes (rebelliousness and bellicosity) that amplified the consequences of climate, a pattern repeated four centuries later….”
