The global warming alarmists need to explain why annual human emissions of CO2 in the 656-ton range are going to destroy civilization, while a CO2 emission of 42 megatons from Mount Pinatubo in 1991 accomplished exactly nothing except giving us a couple of very cold winters.

Anthropogenic global warming is less an environmental or even a political phenomenon than a religious one. Look at Al Gore, who's everywhere on television this week. He's got the lunatic intensity of a religious fanatic.

Thanks for that link. I'd never seen a number for the amount of CO2 released by the Pinatubo eruption.

Your question is self-answerable. The reason for the cold winters was the SO2, which acted as an aerosol in the stratosphere and blocked some incoming solar radiation until it dissipated. 42 Mt is 6.4% of 656 Mt, and Pinatubo was the second-largest eruption of the 20th century -- annual normal volcanic CO2 emissions are much less. I quote a Web site frequently ("Gases: Man versus the Volcanoes") that estimates normal volcanic CO2 emission are 150x less than human (fossil fuel) emissions. Those emissions are why atmosheric CO2 is increasing. (And it won't destroy civilization but it will affect it, I think.)

You need to learn to read. The source says 656 million tons, from the UK alone, per year.

I mean, do the math yourself. If you use 10 gallons of gasoline per week, that's about 30 pounds of gas, or 25 pounds of carbon. That's a little over 1/2 ton of carbon per year or around 2 tons of CO2. Multiply by 250 million Americans, and you get 500 million tons of carbon dioxide per year, just from driving.

You should expect to hear from the lunatic and fanatic communities soon; careful with the insults, this is a family site.

Which is the point I made earlier. In the grand scale of things, human caused CO2 emissions are just the rounding error.
