How long have IR radioscopes been in the air? 50-60 years? Color me pessimistic, but I don't think that they've been orbiting long enough to paint a valid historical picture of what temperature trends have done. Coring polar ice has shown that the temperature on Earth have fluctuated through heating and cooling trends long before man had picked up his first tool and sparked his first fire.
But I'm just a dumb American.
Yeah, but the satellites CAN be used to verify how much heat island effects have contributed to the temperature record
