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.

The curve is roughly 180 degrees out of phase with the C-14 curve.

(Strahler, 1987, p.156) The idea [that the fluctuating magnetic field affects influx of cosmic rays, which in turn affects C-14 formation rates] has been taken up by the Czech geophysicist, V.

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.

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!

We stick the garden hose in and turn it on full blast.

The water coming out of the hose is analogous to the continuous production of carbon-14 atoms in the upper atmosphere.

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.

We say that the input and output of water is in equilibrium.
