Volcanic ash may affect the climate

Volcanic ash, if captured by high-altitude winds, can be dispersed very easily and also make the entire trip around the world. The year 1816 is remembered in the annals of weather as the "year without summer" for temperatures well below the average recorded during the summer months. It now seems established that the lowering of global temperatures has been determined by the dispersion in the atmosphere of massive amounts of ash emitted the previous year by the volcano Tambora, stratovolcano the island of Sumbawa, located in the Indonesian archipelago of Sonda. During the 1815 eruption in the volcanic ash emitted from Tambora in fact constituted a filter solar radiation.
