A lot of people doubt this claim for various good reasons I wont go into here. We believe all the dates over 5, years are really compressible into the next 2, years back to creation. So when you hear of a date of 30, years for a carbon date we believe it to be early after creation and only about 7, years old. If something carbon dates at 7, years we believe 5, is probably closer to reality just before the flood. Robert Whitelaw has done a very good job illustrating this theory using about 30, dates published in Radio Carbon over the last 40 years. One of the impressive points Whitewall makes is the conspicuous absence of dates between 4, and 5, years ago illustrating a great catastrophe killing off plant and animal life world wide the flood of Noah!
I hope this helps your understanding of carbon dating. If you have any more questions about it don't hesitate to write.
I just listened to a series of lectures on archaeology put out by John Hopkins Univ. The lecturer talked at length about how inaccurate C14 Dating is as 'corrected' by dendrochronology. The methodology is quite accurate, but dendrochronology supposedly shows that the C14 dates go off because of changes in the equilibrium over time, and that the older the dates the larger the error. Despite this she continually uses the c14 dates to create 'absolute' chronologies.
She says this is ok so long as you take into account the correction factors from dendrochronology.

They conveniently forget to mention that the tree ring chronology was arranged by C14 dating. The scientists who were trying to build the chronology found the tree rings so ambiguous that they could not decide which rings matched which using the bristlecone pine. So they tested some of the ring sequences by C14 to put the sequences in the 'right' order. Once they did that they developed the overall sequence. And this big sequence is then used to 'correct' C14 dates. Talk of circular reasoning!!!! Nov 07 Read Jan 15 Read At least to the uninitiated, carbon dating is generally assumed to be a sure-fire way to predict the age of any organism that once lived on our planet.
Without understanding the mechanics of it, we put our blind faith in the words of scientists, who assure us that carbon dating is a reliable method of determining the ages of almost everything around us. However, a little more knowledge about the exact ins and outs of carbon dating reveals that perhaps it is not quite as fool-proof a process as we may have been led to believe. At its most basic level, carbon dating is the method of determining the age of organic material by measuring the levels of carbon found in it.

Specifically, there are two types of carbon found in organic materials: It is imperative to remember that the material must have been alive at one point to absorb the carbon, meaning that carbon dating of rocks or other inorganic objects is nothing more than inaccurate guesswork. All living things absorb both types of carbon; but once it dies, it will stop absorbing.
The C is a very stable element and will not change form after being absorbed; however, C is highly unstable and in fact will immediately begin changing after absorption. Specifically, each nucleus will lose an electron, a process which is referred to as decay. Half-life refers to the amount of time it takes for an object to lose exactly half of the amount of carbon or other element stored in it.

This half-life is very constant and will continue at the same rate forever. The half-life of carbon is 5, years, which means that it will take this amount of time for it to reduce from g of carbon to 50g — exactly half its original amount. Similarly, it will take another 5, years for the amount of carbon to drop to 25g, and so on and so forth. By testing the amount of carbon stored in an object, and comparing to the original amount of carbon believed to have been stored at the time of death, scientists can estimate its age.
Unfortunately, the believed amount of carbon present at the time of expiration is exactly that: It is very difficult for scientists to know how much carbon would have originally been present; one of the ways in which they have tried to overcome this difficulty was through using carbon equilibrium. Equilibrium is the name given to the point when the rate of carbon production and carbon decay are equal.
By measuring the rate of production and of decay both eminently quantifiable , scientists were able to estimate that carbon in the atmosphere would go from zero to equilibrium in 30, — 50, years. Since the universe is estimated to be millions of years old, it was assumed that this equilibrium had already been reached. However, in the s, the growth rate was found to be significantly higher than the decay rate; almost a third in fact.
They attempted to account for this by setting as a standard year for the ratio of C to C, and measuring subsequent findings against that. In short, the answer is… sometimes. Sometimes carbon dating will agree with other evolutionary methods of age estimation, which is great.
Is Carbon Dating Accurate?
Most concerning, though, is when the carbon dating directly opposes or contradicts other estimates. At this point, the carbon dating data is simply disregarded. It has been summed up most succinctly in the words of American neuroscience Professor Bruce Brew:
