The are problems with the sfc t record. There are no credible sci challenges to it. This new section is absurdly US-centered, it cannot possibly stand as it it. This is the *global* record we're talking about. You need some credible scientific papers, not pictures of stations. As far as I know, the sfcstations stuff has merely documented problems with some station sitings and maintenance, etc. There is not even the beginning of an attempt at quantifying what influence, plus or minus, this might have on the record. If you're interested, there are papers about the effects of switching from north-wall screens to stevenson screens; thatched huts in africa; etc etc
