There is much debate over whether the Medieval Warm Period was global in extent or not. The MWP is most clearly expressed in parts of North America, the North Atlantic and Europe and parts of Asia
For it to be global in extent, the MWP would need to be seen clearly in more records from the tropical regions and the Southern hemisphere. There are very few palaeoclimatic records for these latter two regions.
It is important to keep this in perspective, however. This dramatic revision of the estimated impact of urbanisation on temperatures in China does not change the global picture of temperature trends. There is plenty of evidence of global warming, not least from oceans far from urban influences. A review of recent studies published online in December by David Parker of the Met Office concludes that, even allowing for Jones's new data, "global near-surface temperature trends have not been greatly affected by urban warming trends."

This paper expresses concern for the "scientific" methods used and the deviation from scientific traditions.
