>>The evidence suggests that over the past 10,000 years there have
been fairly rapid but small fluctuations in C-14 levels (on order
of 1% of present level, taking a small number of decades), as well
as larger longer-term fluctuations (on order of 10% of present
level, taking thousands of years). The latter correlate well with
changes to carbon-14 production rate that would be predicted from
fluctuations in the Earth's magnetic field.>>

Thanks for the added information, Chris. Appreciate it.
