The stations on the map are uniformely distributed, and the temperature trend is a clear representation of the climate status of the region.
In the map cities with a cooling trend are painted blue, tose woith a warming trend in red, and those cities with a small warming trend of less than 1º F are colored in green. This will give a better visual idea of areas with warming, areas of cooling, and areas with no change since 1900, 104 years ago. If there is global warming going on somewhere in the world, clearly it is not in Idaho.
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 has increased steadily, and as CO2 is bla-med for the temperature increase, then 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 - or at least wildly exaggerated.
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. You can get better predictions using Astrology.
