   I have asked Tim to email a map (actually 5 maps) of surface temperature trends for the
   globe,(4 northern seasons and annual) . They are based on all grid boxes with at least 70
   years of data between 1901 and 1999. They are in colour - with anything green ,blue or
   purple  showing negative trend (not robust trends but it won't matter). The bottom line is
   that if you show the annual map in the Synthesis paper, there are quite a few areas that
   have not warmed. Incidentally, the significant trends are indicated as areas enclosed in
   black lines, and southern Greenland and the oceans to the east of it have clearly cooled
   (though most boxes are NOT significant. Other cooling areas are extreme south east USA
   ;west central South America; east central Africa and south east China. Probably 95 per cent
   of the area with data has warmed though.  If you just plug in all areas with at least 25
   years coverage , very large areas of the map cool. I am now thinking and talking about the
   regional projections with Tim.
