Each active volcano produces more Carbon Dioxide than all of mankind. Plants live of it and people like Al Gore make millions spreading insane stories about manmade climate change.
The most asked question at a so-called scientist global warming meeting is "what is for lunch"?
second question "did you get to fly first class or on a private jet" ?
According to the USGS, "Carbon dioxide is abundant in volcanic gases, but not enough to significantly contribute to the greenhouse effect. Volcanoes contribute about 110 million tons of carbon dioxide per year while man's activities contribute about 10 billion tons per year." (See

. You spoiled the fun! The poster was spewing, not carbon dioxide, but denier dreck. You look at a volcano in full eruption and then the tail pipe of a car and it just seems like common sense that there is no way man can emit that much gas. Not only can he, but, as your numbers show, he exceeds the emission from volcanos by 2 orders of magnitude!
I'd bet Jackinthebox is a creationist. They are notorious for not fact checking and taking numbers on faith alone.

A popular myth among climate change skeptics is that volcanic emissions of carbon dioxide dwarf those generated by humans. But a new report in today's issue of Eos reveals precisely the opposite: In a mere 2 to 5 days, smokestacks, tailpipes, and other human sources of CO2 spew a year's worth of volcanic emissions of that greenhouse gas. According to the paper, five recent studies suggest that volcanoes worldwide (such as Alaska's Shishaldin, shown) emit, on average, between 130 million and 440 million metric tons of CO2 each year. But in 2010, anthropogenic emissions of the planet-warming gas were estimated to be a whopping 35 billion metric tons. Individual events—such as Mount Pinatubo, whose major eruption in 1991 lasted about 9 hours—can produce CO 2 at the same rate that humans do, but they do so only for short periods of time. It would take more than 700 Mount Pinatubo-sized eruptions over the course of a year to emit as much carbon dioxide as people do, the study notes.
