Interesting facts carbon dating

When the dipole moment is strong, carbon-14 production is suppressed below normal; when it is weak, carbon-14 production is boosted above normal.What the magnetic field does is to partially shield the earth from cosmic rays which produce carbon-14 high in the atmosphere.

The curve is roughly fitted to mean values determined about every 500 to 1,000 years...It's a great argument except for one, little thing.The water is coming out of the hose at a steady rate as our model assumed!Now, the fuller that barrel gets the more water is going to leak out the thoroughly perforated sides, just as more carbon-14 will decay if you have more of it around.Finally, when the water reaches a certain level in the barrel, the amount of water going into the barrel is equal to the amount leaking out the perforated sides.Contrary to creationist Barnes' totally discredited claims, which I've covered in Topic 11, the earth's magnetic field (dipole moment) has, indeed, increased and decreased over time.Strahler presents a graph of the earth's dipole moment going back 9000 years.That is, we can use carbon-14 dating on a given tree-ring (the 8000-year sequence having been assembled from the overlapping tree-ring patterns of living and dead trees) and compare the resulting age with the tree-ring date.A study of the deviations from the accurate tree-ring dating sequence shows that the earth's magnetic field has an important effect on carbon-14 production.Creationists don't want their readers to be distracted with problems like that -- unless the cat is already out of the bag and something has to be said.Tree-ring dating (see Topic 27) gives us a wonderful check on the radiocarbon dating method for the last 8000 years.
