Iceland has six stations in Iceland with temperature records going back to at least 1940. All show a very warm period around 1940 and sharp cooling from 1940 to 1980.
However, after homogenization five of the six have had their 1940’s blip sharply adjusted down, and the other one shows no change. If homogenization was done correctly, the average temperature of the 1940’s would not have changed. Some stations would increase, others would decrease, but the average would remain approximately the same. (So why do it at all?)
However, none of the stations were increased, and the 1940’s average dropped sharply. This makes no sense from a scientific or mathematical standpoint, and is a smoking gun of fraud. But then again, this is what they planned all along.
It would be good to remove at least part of the 1940s blip, but we are still left with “why the blip”.
Homogenization is a vehicle which serves no purpose mathematically, but allows NASA and NOAA to create warming where there is none. When milk is homogenized, the amount of fat doesn’t change and the amount of milk doesn’t change, all it does is spread the fat around evenly. But when NASA homogenizes temperatures, the amount of heat changes dramatically. Because what they are doing has nothing to do with science.
