Prior To Modern CO2 Emissions: Unprecedented Warming Documented By Scientists - Exceeds Current Temps

Peer reviewed studies continue to be published, adding to the unequivocal evidence that climate change was common in the past, often with temperatures higher than modern averages.
The evidence confirms that modern temperatures are not unprecedented nor that human CO2 emissions are required for climate change to happen.
A new study:"A paper published today in Global and Planetary Change reconstructs temperatures in Northern Fennoscandia [within the Arctic circle] over the past 1,600 years.....demonstrating that the Arctic was warmer than the present during the Medieval Warm Period. The paper adds to over 1,000 peer-reviewed published non-hockey-sticks finding the Medieval Warm Period was global, as warm or warmer than the present, and that there is nothing unusual, unnatural, or unprecedented about the current warm period.....Furthermore, the authors find a natural 70-80 year oscillation of temperatures, similar to the 60-70 year oscillation of the natural Pacific Decadal Oscillation [PDO]."
