I was reading an article online and came across something very interesting. This article shows a very clear link between data collection and warming
observed from 1990 to 2000.
In 1990 the number of observation stations dropped dramatically. Most were rural stations. Coincidentally at the very same time observed surface
temperatures increased. The evidence is clear that surface observations now have a very warm bias with the elimination of rural observation stations
and a heavy U.S. bias with a majority of the stations being in the U.S. So basically U.S. metro areas heavily skew temperature readings.
With this kind of poor data collection and contamination of data it is basically useless to use this information in any kind of accurate scientific
reporting.
