You’ve probably heard of this before...but just in case...

Thanks PGalt.

I see the usual group of know-nothings regurgitated their usual ignorance at the first opportunity.

The headline is spun up to elicit interest, and would be right at home on the cover of a supermarket checkstand tabloid.

Fluctuation of C14 levels has been known at least since the IGY, which began not long after RC dating was pioneered (early postwar; the baseline for dating was 1950), and lasted more than one year.

The reason the fluctuations are known is good old scientific research. That research has allowed RC dating to be calibrated.
