Global Warming? I don't know what to believe.
Scientists do know that while a volcanic eruption displaces a lot of CO2 in the air, the year or two that follows, the Earth goes into a cooling effect due to the contaminants in the air that reflect insolation (solar energy) back into space.
The last major eruption that had serious atmospheric repercussions which happened in 1992 - Mount Pinatubo (Philippines). And "major" eruption is classified as a 6 and above on the VEI (Volcanic Explosivity Index).
Global temps after the eruption for 3 years (!!!) was nearly 1 degree F cooler. Also, there was a significant drop in the ozone with the release of aerosols from the eruption.
Pinatubo was the last major eruption that put more particulate into the atmosphere since Krakatoa (1880s).
These smaller eruptions since Pinatubo, while significant, are not a major contributor to global CO2 levels increasing.

Are you implying "why bother then" or am I just inferring that?
And actually the world is waking up and becoming more conscious of these things.
Europe and Australia is on board when it comes emission controls and pollution. China is starting to change their ways. I'm not sure about Russia, Africa or South America, but us folks in America aren't the only ones who are caring about this issue.
And sure it may take decades to change, but it will happen. The traditions of your fathers are dying at a rapid pace and the younger generations are stepping up to the plate.
