    3. Tropical eruptions are climatologically more important. The theory (Eruptions, p.72-3) seems to be that high latitude eruptions have less effect...

    This perhaps shows more clearly the greater effect of El Chichon (1982) than Pinatubo (1991) on the Arctic ice, though, again, we have trend-lines...

    So, if El Chichon removed more heat from the oceans than Pinatubo, and removed the bulk of it from the NH, you might expect some kind of effect on...
