What has piqued my interest today is a postulation that Solar Minima are linked with increased volcanic activity. A brief Google brought not immediate information, but enlightenment of a different type. This year there have been not one but three eruptions in the Aleutian Island chain linking Alaska to Russia. The most notable for its large SO2 plume, Kasatochi, but also Cleveland and Okmok which are geographically very close. Of course, many volcanoes smoke all the time.
However, I shall have a play around the interweb and examine the available historical records to see if there is any cyclic behaviour. Hmm.
