Eruption of Mount Tambora
The mightiest blast in recorded history cools the whole planet

In April 1815 Tambora produced the most powerful eruption in recorded history: the mountain lost over a kilometre of height and an estimated 70,000+ people died. Its stratospheric ash cooled the planet. Two months later, Napoleon lost at Waterloo.
