Peer Reviewed Science: Chinese Scientists Prove Medieval Period Warmer Than Recent Modern Warming

Using sediment cores from two lakes in the Qaidam Basin of the northern Tibetan Plateau, Chinese researchers reconstructed temperatures back some 2,000 years.

Their research was unequivocal: modern warming has been cooler than past warming periods. They also confirmed that the climate naturally made shifts between warm/cool regimes.  Plus, the climate shifts appear to be associated with solar activity.
