Here’s one to upset the climate alarmists: the theory behind the fraudulent “hockey stick” was that the Earth’s climate was relatively stable until recently, when man began pouring CO2 into the atmosphere. That required the denial (Oh, irony!) of cyclic warm and cool periods in the past, since such cycles challenge the theory of runaway warming. This study provides more strong evidence of one of these warm phases, the Medieval Warm Period. Perhaps the Pope should read this, too.

SYDNEY — University of New South Wales Australia-led research on limestone formations in a remote Scottish cave has produced a unique 3000-year-long record of climatic variations that may have influenced historical events including the fall of the Roman Empire and the Viking Age of expansion.
The study of five stalagmites in Roaring Cave north of Ullapool in north-west Scotland is the first to use a compilation of cave measurements to track changes in a climate phenomenon called the North Atlantic Oscillation.
