In 1816, the sky turned brass. Crops froze in June. The air smelled of burned stone. The official explanation: one volcano in Indonesia. But the timing doesn't match. The geographic distribution doesn't match. And the atmospheric accounts from New England to Central Asia describe something no volcanic eruption produces.
The same decade the sky went wrong is the same decade Tartaria disappeared from the maps.
This is the investigation they never ran. The letter that was never cited. The pattern that was never connected. And the question no climate historian has ever asked: what else was burning in 1816?
