The satellite and thermometer technologies seem to be diverging in what they are telling us in recent years, with the thermometers continuing to warm, and the satellite temperatures essentially flat-lining.
So, why have world governments chosen to rely on surface thermometers, which were never designed for high accuracy, and yet ignore their own high-tech satellite network of calibrated sensors, especially when the satellites also agree with weather balloon data?
I will leave it to the reader to answer that one.
