Description
English: Correlations between 14C and sunspot activity.

Note that the 14C record since 1950 has been distorted by nuclear testing. Sunspot data in red is reconstructed from group sunspot numbers.

(Vertical alignment for 14C is correct in my editor, corrections for Wikipedia rendering are welcome.)
