Hey Al Gore Got Bad New's For You, Advanced Computer Models Suggest Most Global Warming Is From Natural Forces
“This suggests that even if there had been no industrial revolution and burning of fossil fuels, there would have still been some warming through the twentieth century – to at least 1980,” according to lead author Jennifer Marohasy.
The world was about as warm in 1980 as it was during the Middle Ages when the Vikings settled Greenland and “when men dressed in tunics and built grand cathedrals with tall spires,” Marohasy wrote in The Spectator Australia on Tuesday, summarizing her study’s results.
Climate scientists Marohasy and John Abbot used a sophisticated artificial intelligence-like computer system to see what temperatures may have done since 1830 without human influence based on proxy climate records going back to 50 A.D.
The ANN system is a “form of machine learning: think big data and artificial intelligence,” …
