The stations on the map are uniformely distributed, and the temperature trend is a clear representation of the climate status of the region.
We have colored in the map cities with their corresponding trend colors: blue for cooling and red for warming. We see that warming was pronounced since 1900, but the warming trend has slowed down considerably since 1950. Cities in the map with a blue circle with an inner red dot means stations showing a cooling trend since 1950. While the trend since 1900 is +1.85º F (0.18º F per decade), the warming trend has slowed down to 0.071º F per decade since 1950, showing that the warming trend in the US (and the world) is reaching to an end. We should be expecting some cooling during the next 10 years - and a severe one by 2030, time when the Double Solar Minimun Gleissberg is predicted, according to late Dr. Theodor Landscheidt (see: Solar Wind Near Earth: Indicator of Variations in Global Temperature).
Global warming means there is an overall warming everywhere in the world, but there must be a reason for the cooling in some regions - reason that has not been explained by any climate model. As CO2 is blamed for the temperature increase and, as CO2 has increased steadily, there shouldn't be any cooling anywhere. As we see cooling in many places around the world, the relation between CO2 and temperature increase is a false one.
Furthermore, as the relation between CO2 and temperature is derived from computer models, these climatic models are not an accurate image of the climatic system, and they cannot give an accurate prediction of the future climate.
