The thing is that the widespread believe in global warming doesn't just stem from temperature measurements, but a multitude of other observable facts that do fit in the theory (i.e. experiments do not invalidate the theory).

But just picking up your satellite argument. A quick google search reveals many articles disputing that satellites show no increase in global temperatures. One article [1] even claims corrected sattelite measurements show a higher increase than surface measurements.
