Well, someone needs to tell all the Volcanoes to stop erupting.
And Bush will support anything if he thinks he can make money on it.
"Present-day carbon dioxide (CO2) emissions from subaerial and submarine volcanoes are uncertain at the present time. Gerlach (1991) estimated a total global release of 3-4 x 10E12 mol/yr from volcanoes. This is a conservative estimate. Man-made (anthropogenic) CO2 emissions overwhelm this estimate by at least 150 times. "

From article at
http://www.defra.gov.uk/environment/climatechange/index.htmExplosive eruptions can inject large quantities of dust and gaseous
material (such as sulphur dioxide) into the upper atmosphere (the
stratosphere - see Figure 1.1, section 1.2.2), where sulphur dioxide is
rapidly converted into sulphuric acid aerosols. Whereas volcanic pollution
of the lower atmosphere is removed within days by the effects of rainfall
and gravity, stratospheric pollution may remain there for several years,
gradually spreading to cover much of the globe.
The volcanic pollution results in a substantial reduction in the
direct solar beam, largely through scattering by the highly reflective
sulphuric acid aerosols. This can amount to tens of percent. The reduction,
is however, compensated for by an increase in diffuse radiation and by the
absorption of outgoing terrestrial radiation (the greenhouse effect).
Overall, there is a net reduction of 5 to 10% in energy received at the
Earth's surface.
