The stations on the map are uniformely distributed, and the temperature trend is a clear representation of the climate status of the region.
Indiana has cooled by -0.22ºF in 104 years. There will be no catastrophes related with warming in Indiana. By looking at the map, and seeing how temperatures go up and down in small areas, the idea of a global warming becomes increasingly ridicule as there are no signs of such "dramatic" warming.
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.
