Read here. Across the globe, more evidence is being found that indicates that the Medieval warming temperatures were definitely higher than the current "unprecedented" temperatures mistakenly(?) claimed by politicians. The latest peer-reviewed research out of China confirms this.
...they say that "regional proxy temperature series with lengths of 500-2000 years from China have been reconstructed using tree rings with 1-3 year temporal resolution, annually resolved stalagmites, decadally resolved ice-core information, historical documents with temporal resolution of 10-30 years, and lake sediments resolving decadal to century time scales,"...Since portions of two of the four sections of China for which temperature reconstructions extended far enough back in time to sample the Medieval Warm Period exhibited temperatures comparable to those of the late 20th century, and since portions of two other sections actually revealed parts of the Medieval Warm Period to have been warmer than the late 20th century, it is clear that there is nothing unusual, unnatural or unprecedented about the country's current level of warmth. Hence, by the reasoning set forth by Ge et al. in the introduction to their study, there is no compelling reason to attribute late 20th-century warmth in that sprawling country to 20th-century increases in the air's CO2 concentration...
