While reading the Climategate emails, I chanced upon a message to Phil Jones from a Chinese researcher, Yan ZhongWei inquiring if the great man would like to be a co-author on a forthcoming paper.

Hi, Phil, Attached please find a draft paper about site-changes and urbanization at Beijing. It may be regarded as an extension of our early work (Yan et al 2001 AAS) and therefore I would be happy to ask you to join as a co-author. Regarding your recent paper about UHI effect in China (no doubt upon a large-scale warming in the region), I hope the Beijing case may serve as a helpful rather than a contradictory (as it may appear so) reference. The urbanization-bias at BJ was considerable but could hardly be quantified. I suspect it was somehow overestimated by a recent work (Ren et al 2007). Please feel free to comment and revise. I'll check and complete the reference list, while you may also add in new references Cheers Zhongwei

Well if the paper appeared contradictory, showing a substantial UHI, then I wanted to know about it. This appears to be it. Here's the abstract:
