Mass grave in London reveals how volcano caused global catastrophe
Scientists search for the explosive source of a disaster that wiped out almost a third of Londoners in 1258

A more recent one caused the “18 hundred and froze to death” 1816 in the northeast US and I’ve read Northern Europe. “Mechanics” those then employed in shipbuilding in Setauket, NY (about 100?) had to wear their winter coats in July. Crops didn’t grow in “the year without summer” from the atmospheric dust from the volcano explosion in Indonesia, then too. I think “middlemen” ports like Baltimore, MD profited by shipping needed comestibles north. Not sure if however, there was such a large effect on the population as this dramatic archaeology research shows. US populations were quite lower. On Long Island, where it’s reported 10,000 cords of wood were cut for the War 1812, it might have had effect, a primary source of heat then, coal wouldn’t show up until 1840 or so, though early expeditions were organized as far back as the days of Oliver Cromwell in Huntington, NY to look for coal to fire brick.
