Abstract
Radiocarbon activity was negatively correlated (P≤.01) with a sunspot-auroral index during 25 designated solar activity periods from 129 B.C. to A.D. 1964. Change in carbon-14 activity during these periods was inverse to change in solar activity in 22 of 24 instances (P≤.001). Contamination from carbon-14 formed during previous solar cycles mnay lessen the value of carbon-14 as a climate or solar index.This publication has 17 references indexed in Scilit:
