No, but its a fact temperature measuring was started earlier here than most places, and was and is much more extensive here. England is probably next, then the continent - I think the world wars disrupted a lot of the record keeping there. In the third world (which is most of the world), temperature measurements only began relatively recently and still aren't very extensive. And they are centered in big cities. Thus the quality is likely low and affected by the urban heat island effect. The urban heat island issue is known and real and if most of the third worlds measurement sites are in large cities (and they are) then its likely biasing recent decades measurements upward.
