It matters where it erupts


No, not that rash you've been worrying about.  This is on the topic of  volcanoes and Earth's climate.


Volcano eruptions at different latitudes impact sea surface temperature differently

"Analysis of the simulations indicates that the Pacific features a significant El Nino-like warm SST anomaly 5-10 months after northern and tropical eruptions, with the Nino3 index peaks at the winter of next year.

Compared with northern eruptions, the warm SST anomaly is mainly confined to the eastern Pacific with a stronger intensity following tropical eruptions. Following southern eruptions, the Pacific shows a weaker warming anomaly over the eastern Pacific and the time at which the Nino3 index reaches its peak is about 4 months earlier than that after northern and tropical eruptions."

I find that intriguing.

Just to remind us all what a volcanic eruption looks like (in this case, Indonesia's Mount Bromo):
