Do Volcanoes emit more CO2 than humans?

The answer is No. It is a common misconception that volcanoes emit more carbon dioxide than humans. I found the raw data to prove it (https://spreadsheets.google.com/ccc?key=0Aqe2P9sYhZ2ndERxaWs2TU1iaDU1QW9ldzBzQXBpbkE&hl=en_GB#gid=0)

World human CO2 emission per year are 27 trillion metric tons. Volcanoes worldwide on the other hand only emit 180 million metric tons of CO2. Humans thus emit 150 times as much CO2 as all volcanoes combined per year. If you still think volcanoes suck, take them down a peg.
