Earth Was Warmer in Roman, Medieval Times

“For many years now, there was an alleged scientific consensus that the Earth was warming due to humans releasing greenhouse gases into the air — primarily through burning fossil fuels. However, temperatures stopped rising after 1998, leaving scientists scrambling to find an explanation to the hiatus in warming.

Increasingly, scientists are looking away from human causes and looking at solar activity and natural climate variability for explanations of why the planet warms and cools.

“All other things being equal, adding more greenhouse gases to the atmosphere will have a warming effect on the planet,” Judith Curry, a climatologist at the Georgia Institute of Technology, told the Los Angeles Times. “However, all things are never equal, and what we are seeing is natural climate variability dominating over human impact.”

The Kullman study points to mounting evidence that climate is largely out of human control, as humans were not burning large amounts fossil fuels during Roman and Medieval times.

Some scientists have pointed to solar activity as the predictor of where global temperatures are headed. Researchers have pointed to falling sunspot activity as evidence that the planet will cool off in the coming decades.”
