A series of carbon-14 measurements of 18th- and 19-century wood revealed an excellent correlation between the variations in carbon-14 content and average sunspot activity. It seems probable, therefore, that the predominant cause of the short-term fluctuations in carbon-14 activity is the variability of solar activity.
对18世纪和19世纪木材进行的一系列碳-14测量显示，碳-14含量的变化与太阳黑子平均活动之间存在着极好的相关性。因此，碳-14活动短期波动的主要原因很可能是太阳活动的变化。
