You are greatly twisting and misinterpreting information. After some research it
turns out you're terribly incorrect. Volcanoes spew out more *pollutants* such
as SO2 than humans, but volcanoes do ***NOT*** create any where near as much CO2
as humans. In 2003 humans created ~140 times more CO2 than all the volcanoes on
the entire planet combined, including all the volcanoes under water, and it's
probably higher in 2007..

Scroll down to "Comparison of CO2 emissions from volcanoes vs. human activities"

Here's Al Gores Global Warming speech:

Scroll to 27:12 minutes to see the CO2 & temperature chart spanning the past
400,000 years that includes present humanity. See all of the ice age cycles, but
when it hits modern time the CO2 spikes to ~5 times the maximum of any ice
age!!! Here's an image of the chart -->

Notice how CO2, yellow line at the right, suddenly increases by ~5 times the max
of any ice age when modern humanity arrives. That is Global Warming!!! It is
*NOT* caused by volcanoes.
