Read here. Another peer-reviewed study proves the IPCC speculative claim that modern temperatures are "unprecedented" is bogus.
Although the infamous Climategate scientists attempted to force the false "hockey stick" caricature of historical temperatures on the public, the on-going scientific research continues to discover that Medieval Period temperatures were, on average, higher than our present temperatures.
Per a new study, a lake in Switzerland provides evidence from sediment cores that refutes IPCC's propaganda that modern temperatures are warmer than past temperatures. (click on image to enlarge)
"Based on their analysis of fossil chironomids that were identified and quantified in four sediment cores extracted from the bed of Lake Silvaplana in the eastern Swiss Alps, plus a previously developed 101-lake transfer function, Larocque-Tobler et al. constructed a detailed history of that region's mean July air temperature over the last millennium.....it can be seen that the peak mean warmth of the Medieval Warm Period exceeded that of the Current Warm Period by approximately 0.5°C in the case of 20-year averages and 1.2°C in the case of 50-year averages."
