I'm a bit confused by all this Global Warming stuff. Please set me straight with real science.
I think you have the figures the wrong way round?
"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) [ ( Marland, et al., 1998
) - The reference gives the amount of released carbon (C), rather than CO2.]. 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)!"
where did your 98% figure come from?
