That is cr*p! If you had paid attention you would know that the
temperatures have not risen since 1998. Record there are few record
gloabl tempeartures, although there are quite a few local highs
happpening. eg. Russia.

do we actually
*know* that a quality control check is done on the raw data? I'm just
looking on 'Ogimet' at Alaska and Canada and there are roughly ten
stations reporting way off temperatures. One is showing 28 degs when
nearby stations are around 0 to 3 degs. Presumably most of these are
automatic stations and they will transmit whatever their sensors say
even if they are wildly out. From my experience there seems to be a
definite bias towards high temperature 'wrong' readings rather than
the odd low one. Any thoughts?

Why don't you report them, and see what answer you get?
