What was the result of the eruption of Mount Tambora?

Answer 1

That such an eruption changes the climate of the entire planet. When there's a large volcanic eruption somewhere, deep volcanic ash covers an area of several tens of miles surrounding the volcano. Airborne ash settles to the ground rather quickly - several days or weeks. So this is a local event. However the sulfur gas from a large eruption is propelled into the stratosphere and beyond, above the clouds where rain and wind can scrub these contaminants from the air, remain there for 1-2 years. Sulfuric gas combines with water molecules to form an aerosol that acts like a veil covering the entire planet preventing most of the sunlight from reaching the ground. Hence the earth looses 1-2 growing seasons as photosynthesis stops and crops are unable to grow. This occurred in 1815, a year known as the year without a summer, when the world faced its last subsistence crisis, or famine. Tens of thousands people and an untold number of animals and livestock died in America and Europe when Tambora had that large eruption. Now, all these things happen during a supervolcanic eruption too - except that the world would loose between 8 and 10 growing seasons, instead of only 2. There are at least a dozen such supervolcanoes worldwide (three in the U.S.) in which these conditions would occur should a large eruption happen.

Answer 2

No summer!!!!!!!!
