We examine the relationship between the GISP2 dust profile, a proxy for the Northern Hemisphere atmospheric dust load, and the Wolf sunspot number, a proxy for solar activity. The two records are positively correlated, but the phase of the relationship is disturbed by the effects of explosive volcanism. Similar correlation failures have already been noted for many other climatic indicators. Our work suggests that a large fraction of the correlation failures may be attributed to explosive volcanic activity.
