Unprecedented Global Warming: New Study Establishes Summer Temps Hotter During Medieval Warming Period
The IPCC's now discredited 'hockey stick' temperature record attempted to change paleo-climate history by finding modern temps to be unprecedented - another new study confirms Medieval Warming Period was hotter
Read here. Paleo-climate research continues across the world and the vast majority of new studies confirm that earlier periods were warmer than our current climate. And the newest research establishes the same for Canada's Yukon region.
""Bunbury and Gajewski obtained sediment cores from Jenny Lake that "yielded chironomid records that were used to provide quantitative estimates of mean July air temperature."... This effort revealed the existence of "relatively warm conditions during medieval times, centered on AD 1200, followed by a cool Little Ice Age, and warming temperatures over the past 100 years." And from the authors Figure 8, reproduced below, it can be estimated that the Medieval Warm Period at Jenny Lake extended from about AD 1100 to 1350, and that the most recent (AD 1990) of their temperature determinations was about 0.8°C cooler than the peak warmth of the Medieval Warm Period." [Joan Bunbury, Konrad Gajewski 2012: Quaternary Research]
Conclusion: The Medieval Period had the unprecedented global warming, not our modern period. The Medieval warming took place during a time of low atmospheric levels of CO2, well before the modern growth of CO2 emissions.
