Jacob:
"The main gas emitted by volcanoes is methane, not CO2."
No. The main gases are steam, CO2, SO2 and CL.
See reference below.
In fact the Alaska Volcano Observatory occasionally flies an instrument called a COSPEC to Mt. Spurr and other Alaskan volcanoes. It measures CO2 and SO2. Elevated levels of these gasses sometimes precede eruptions.
There is still a lot of controversy about Global Warming. So much in fact, that the discipline that studies it changed its name from "Global Warming" to "Global Change". There is also much disinformation. The case is far from closed.

All magmas contain dissolved gases that are released both during and between eruptive episodes. Volcanic gases generally consist predominantly of steam (H2O), followed in abundance by carbon dioxide and compounds of sulfur and chlorine (Wilcox, 1959; Thorarinsson, 1979). Minor amounts of carbon monoxide, fluorine and boron compounds, ammonia, and several other compounds are found in some volcanic gases. |
