I hear this all the time and it really confuses me. Volcanoes spew up water vapor, carbon dioxide and sulpher dioxide. The carbon dioxide amounts to 130-230 teragrams of carbon dioxide each year. That is 130 million metric tons. In 2003, according to the Energy Information Administration was 45 times higher, at 5,780.2 million metric tons. So, one nation produced 45 times more than all the volcanism in the world.
And volcanoes, main output sulpher, acts to cool the lower atmosphere and earth's surface by increasing reflection of solar radiation. If you aren't aware, chemical reactions change sulpher dioxide to sulphuric acid. This aerosol acts as nuclei for water vapor. More cloud coverage means a lower temperature. This is why temperature dipped slightly after Mt. Pinatubo's eruption in the mid 20th century.
So anyway my point is why do people say OH VOLCANOES ARE WAY WORSE THAN HUMANS. Or BLAME VOLCANOES FOR GLOBAL WARMING. Where does this misinformation come from?!
