In order to prove that theory , ecologists have turned to historical data in relation to especially huge volcanic eruptions. They suspect that volcanoes effect weather changes that are similar to air pollution. One source of information is the effect of the eruption of Tambora, a volcano in Sumbawa, the Dutch East Indies, in April 1815. the largest recorded volcanic eruption, tambora threw 150 million tons of fine ash into the stratosphere. The ash from a volcano spread worldwide in a few days and remains in the air for years. Its effect is to turn incoming solar radiation into space and thus cool the earth. For example, records of weather in England show that between April and November 1815, the average temperature had fallen 4.5oF. During the next twenty four months , England suffered one of the coldest periods of its history. Farmers records from April 1815 to Decenver 1818 indicate frost through out the spring and summer and sharp decrease in crop and livestock markets.
