YESTERDAY WAS THE 200TH ANNIVERSARY of the eruption of Tambora. “The April 10, 1815 eruption of Tambora in what is now a part of Indonesia caused 1816 to be known as ‘the year without summer.’ Crop failures due to freezing temperatures in New England caused migrations toward the midwest.. Migrations, civil unrest, hunger, and disease happened in Europe as well. A volcanic eruption of this magnitude is rare but could happen again at any time. If it does expect very expensive food and freezing temperatures on some summer days.” Ugh.
