Man Vs. Volcano

Which is worse?





I've heard some stupid things in my life, but the claim that a volcano releases more CO2 in one spit than all of industry over the last 150 years has to be the stupidest. For the record, let's use the USGS as a reference. They state.....

Scientists have calculated that volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1999, 1992). This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 22 billion tonnes per year (24 billion tons) Human activities release more than 150 times the amount of CO2 emitted by volcanoes--the equivalent of nearly 17,000 additional volcanoes like Kilauea.

O.K. I feel better now.
