Anyone who has studied things knows that many of the temperature reporting stations in Siberia have been relocated to warmer areas since the 1980’s.
Doesn’t take a rocket scientist to understand the net result.
And contrary to what we are told, the hottest decade in the 20th century was the 1930’s, not the 1990’s.
And many of the reporting stations in the US, and around the world, are in 'heat island' locations, so the temps are usually higher than in the surrounding areas.
The satellite temperature readings have been showing either no increase or a slight decrease in overall temps over the last few years. That tracks precisely with the diminished number of sunspots for the last four years, and the slow start to this most recent sunspot cycle.
