Nobody is impressed by your stupid stories of having been a weatherman in the air-army. Annual average volcano emissions are three orders of magnitude smaller (that's 1/1000, for the innumerate in the audience) than human CO2 emissions from fossil fuel combustion. And you can't fucking _see_ CO2 anyway. It's fucking invisible. Whatever you saw from that volcano was water or dust or ash or whatever, the things that volcanoes spew into the upper atmosphere that counteract the warming effect of their CO2 emissions.
