Another Source of Rising Mean Global Temperature

This is not the easiest graph to read but there are two big changes on it: As the number of reporting surface stations drops by over 2/3rds (from nearly 6000 to less than 2000) the temperature jumps up. That's because the stations lost were in Siberia and Canada and otherwise in rural areas and the remaining ones were in urban and suburban areas where, more often than not, they were improperly sited to record a higher temperature than a properly sited station would show. It's not the rising CO2, it's the measurers and even the unreliable measurers show cooling for the past decade or so. More on the subject here. From Joseph D’Aleo, CCM, AMS Fellow, via ICECAP


Gee, the number of stations graph looks kind of like stick.
Well noticed, mann.
