High-latitude volcanic eruptions affect ocean circulation for decades

(Phys.org)—It's well known that tropical-latitude volcanos have dramatic, global effects on atmosphere and climate. In fact, a new and startling book, Tambora: The Eruption That Changed the World, by Gillen D'Arcy Wood, documents the catastrophic eruption of the Tambora volcano in 1815, and the decade of climate change and global chaos that followed. Tamobora, a peninsula of the island of Sumbawa in Indonesia, is just such a tropical volcano.
