Promoters of man-made climate catastrophe state categorically that our current temperature is “unusual and unprecedented” on a scale ot thousands of years. This chart by Moberg et al is a multi-proxy paleo temperature reconstruction of the last 2,000 years using both high and low resolution data. The Medieval Warm Period was the most recent warming period and likely had similar or warmer temperatures than modern ones. Bear in mind that this warming was driven by natural forces and occurred in a period of very low carbon dioxide concentrations.
