BBC gets it right on Volcanoes
December 28, 2010
I heard it just a few weeks ago in a Q and A session. ‘Volcanoes release way more co2 than humans.”
As the commentator above relates, and as the US Geological Survey affirms, humans release 100 times more CO2 annually than all the world’s volcanoes. When you hear this canard, point your denialist friend to the USGS Volcanic Gases and Climate page, where they can read it from the horse’s mouth.
Do the Earth’s volcanoes emit more CO2 than human activities? Research findings indicate that the answer to this frequently asked question is a clear and unequivocal, “No.” Human activities, responsible for some 36,300 million metric tons of CO2emissions in 2008 [Le Quéré et al., 2009], release at least a hundred times more CO2 annually than all the world’s degassing subaerial and submarine volcanoes (Gerlach, 2010).
As far as the recent Icelandic volcanic eruption, USAToday quotes Caspar Ammann of the National Center for Atmospheric Research:
What’s unlikely from the Eyjafjallajökull eruption is any major climate effect, says climate scientist Caspar Ammann of the National Center for Atmospheric Research in Boulder, Colo. “Right now, the magnitude and explosiveness of the Icelandic eruption is not enough to have significant climate effects.”
I touched on this in the video below, where you can see the crock presented in it’s most bald faced, dishonest form, from the “Great Global Warming Swindle” swindle.
