The stations on the map are uniformely distributed, and the temperature trend is a clear representation of the climate status of the region.
Somebody could say that someone forgot to turn the heating in Nort Dakota, especially when compared with so many other states where there is a notorious cooling. However, warming in North Dakota has been just 1º C in a 100-year perios, that is, 0.1º C per decade. We could say it is well within a natural variation climatic change.
But, when this page was being assembled, we received the news that from Friday, August 20th, through Sunday, August 22nd, 2004, terrible early frosts fell the US midwest area, namely the states of Minnesota, and both Dakotas, North and South, with temperatures ranging between 5,0 y 6,0º C below zero, causing the loss of about 50 and 100% of soybean and corn crops. Soybean prices went up on Chicago the next Monday becasue these three states contribute to about 23% of the US soybean production. This very bad news can be found at: August Frosts Wilts Crops, in Minnesota's Startribune.
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.
