Whatever variation may exist, carbon dating has been independently verified via other dating means such as coral ring formations and dendrochronology. Unless whatever is having an effect on carbon dating also affects these other, unrelated, forms of dating in the exact same way we can expect the variation to be small and not significant enough to upend everything we know. The evidence that our dating mechanisms work is undeniable - tectonic movement, linguistic evidence of language dispersion, physiological changes in species and their geographical distribution, etc etc all happen at predictable rates and all match up with what we know about our dating methods.
Really, creationists should be better suited applying their ultra-skepticism at the much larger gaps in evidence and analysis found in their own ideas. The thing about people who value science is that whenever data presents a challenge we have to account for it, unlike the idiot creationists who only embrace data when it agrees with their already pre-conceived ideas.
