Let's see. . . two minute Google search and vioala!
Volcanic production average per year: 130 million tonnes per year vs Billions of tonnes by human consumption.
Comparison of CO2 emissions from volcanoes vs. human activities. 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 (Kilauea emits about 13.2 million tonnes/year)!
Yeah I can't wait until the methane ice is released from Siberia's deep freeze. Look if it really gets warm you want to buy land in Siberia and Northern Canada. The open artic ocean will be the 21st centuries Mediterranean of commerce.

"Since 1751 roughly 290 billion tons of carbon have been released to the atmosphere from the consumption of fossil fuels and cement production. HALF of these emissions have occurred since the mid 1970s. The 2002 global, fossil-fuel CO2 emission estimate, 6975 million metric tons of carbon, represents an all-time high and a 2% increase from 2001.
