Curry and Mosher claim that UHI has no impact on rural vs. urban temperature trends. I put that to the test in New South Wales, with two of the longest temperature records in Australia.
Sydney Observatory is right next to 20 lanes of asphalt and has warmed almost 2C since 1860.
Forbes is a rural station and has cooled about one degree since the 1870’s.
This is the same pattern we see at all the old rural stations in Australia like Deniliquin, Bourke, etc. SE Australia has cooled since the 19th century.
The correct conclusion for Curry and Mosher to have drawn from their study is that their approach, including using the Modis night lights approach to identifying rural stations, is flawed – rather than their nonsensical conclusion that UHI hasn’t affected the temperature record.
