Wouldnt all that excess c14 mess up the carbon 14 chronologies? How could c14 be a reliable universal chronometer if the amount in ambient atmosphere can vary from place to place based on solar activities and atmospheric distribution?

They calibrate out the natural year to year variations in 14C out by measuring known date samples, usually tree rings, which have an unbroken sequence dating back as far as 14C can be used.
