What is the difference between global temperature and average temperature? And, how are they calculated?

My reply:

Sorry, but global temperature is a non-measurable concept, and it is impossible to declare one year warmer or colder than another. That doesn’t stop the U.N. IPCC money-grabbing criminal hydra from doing it, of course always declaring each year warmer than the one before because they’re holding their hands out promising a solution that they know they can’t deliver. Since forever most of the reliable temperature measurement stations are in the U.S., which doesn’t stop hijacked scientific organizations from pretending they get valid data from all over the globe, because they brazenly substitute statistics, even though as they say, statistics lie, kaching!
