New Science Confirms: Earth was WARMER During Medieval Period

The researchers’ evidence also shows that it was actually around one degree warmer throughout Europe during that time, confirming past studies. Some researchers have used remodeling in their favor to flatten the Medieval Warm Period and try to downplay its significance, but hundreds of scientists from 40 countries around the world have contributed peer-reviewed papers proving that the Medieval Warm Period was warmer than the present and this study is just the latest.

The findings of Marohasy and Abbot add to a growing mountain of evidence pointing to warmer temperatures during the past. According to a report from the Center for the Study of Carbon Dioxide and Global Change, the Medieval Warm Period was not only warmer than the current period, but it also lasted longer than the current warm period and was global in scope.

A comprehensive study out of Germany published in Nature Climate Change examined tree ring data and found that earlier estimates of historical temperatures during times like the Middle Ages and Roman Era were too low.

If the climate has been warmer in the past in the absence of any significant carbon dioxide emissions, it means that CO2 emissions do not have the huge impact on the climate that some parties with vested interests claim. It might be true that greenhouse gases can have a warming effect, but experts like respected climatologist Judith Curry believe that natural climate variability is playing a much stronger role in all this than human impact.
