Satellites show that temperatures at Canberra have been declining at 2.2C/century since 1997.
But surface temperatures have been rising at 7.1C/century
This probably has something to do with the fact that BOM placed their thermometer right next to a huge parking lot.
GISS claims that they adjust for UHI, but in fact they do almost nothing to correct the problem. They shift all post-1940 temperatures down by about an equal amount, and leave behind the completely fake sharp warming trend at Canberra.
One more indication that the surface temperature record from GISS and BOM is a farce.
