Warming Alarmists Could Use Lesson On History Of Climate Change - Investors.com

"In the Medieval Warm Period (MWP), from the end of the 9th 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.

Warming increased the amount of arable land — there were vineyards in northern England — leading, Rosen says, to Europe's "first sustained population increase since the fall of the Roman Empire." The need for land on which to grow cereals drove deforestation. The MWP population explosion gave rise to towns, textile manufacturing and new wealthy classes.

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 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."
