3 Weeks Until Doomsday

Not angry at all, used to dealing with the intellects of five year olds. I am a grandfather, after all.

Which emits more carbon dioxide (CO2): Earth’s volcanoes or human activities? Research findings indicate unequivocally that the answer to this frequently asked question is human activities. However, most people, including some Earth scientists working in fields outside volcanology, are surprised by this answer. The climate change debate has revived and reinforced the belief, widespread among climate skeptics, that volcanoes emit more CO2 than human activities [Gerlach, 2010; Plimer, 2009]. In fact, present-day volcanoes emit relatively modest amounts of CO2, about as much annually as states like Florida, Michigan, and Ohio.

Volcanic emissions include CO2 from erupting magma and from degassing of unerupted magma beneath volcanoes. Over time, they are a major source for restoring CO2 lost from the atmosphere and oceans by silicate weathering, carbonate deposition, and organic carbon burial [Berner, 2004]. Global estimates of the annual present-day CO2 output of the Earth’s degassing subaerial and submarine volcanoes range from 0.13 to 0.44 billion metric tons (gigatons) per year [Gerlach, 1991; Allard, 1992; Varekamp et al., 1992; Sano and Williams, 1996; Marty and Tolstikhin, 1998]; the preferred global estimates of the authors of these studies range from 0.15 to 0.26 gigaton per year. Other aggregated volcanic CO2 emission rate estimates—published in 18 studies since 1979 as subaerial, arc, and mid-oceanic ridge estimates—are consistent with the global estimates. For more information, see the background, table, and references in the online supplement to this Eos issue (AGU - American Geophysical Union).

Anthropogenic CO2 emissions—responsible for a projected 35 gigatons of CO2 in 2010 [Friedlingstein et al., 2010]— clearly dwarf all estimates of the annual present-day global volcanic CO2 emission rate. Indeed, volcanoes emit significantly less CO2 than land use changes (3.4 gigatons per year), light-duty vehicles (3.0 gigatons per year, mainly cars and pickup trucks), or cement production (1.4 gigatons per year). Instead, volcanic CO2 emissions are comparable in the human realm to the global CO2 emissions from flaring of waste gases (0.20 gigaton per year) or to the CO2 emissions of about 2 dozen full-capacity 1000-megawatt coal-fired power stations (0.22 gigaton per year), the latter of which constitute about 2% of the world’s coal-fired electricity-generating capacity. More meaningful, perhaps, are the comparable annual CO2 emissions of nations such as Pakistan (0.18 gigaton), Kazakhstan (0.25 gigaton), Poland (0.31 gigaton), and South Africa (0.44 gigaton). (CO2 emissions data are for 2008 [International Energy Agency, 2009a, 2009b]; see also http://cdiac.ornl.gov/trends/ emis/meth_reg.html, US Environmental Protection Agency cleanenergy/energy-and-you/affect/coal .html, and UEA: Interactions between Ocean Biogeochemistry, Physics and Climate lequere/co2/carbon_budget.htm.)

Just have to love it when really stupid people post on issues they know absolutely nothing about. Lassie, you are about as dumb as a brick. Had you bothered to do the slightest research you would have seen how incorrect that silly picture is. Instead, you just flap your ignorant yap, mindless and heedless of what the truth is.

The EPA? LOL Dude nobody buys what the EPA is selling....unless of course it's an idiot loon like you

Old Rocks is correct. Contemporary human emissions dwarf any vulcanism seen since the Deccan Traps

I've read your drivel, I don't take you anymore serious than I do the old dude

You're call. If you want to continue to look like an idiot, I've no reason to stop you.

Dat's good...

... gives Granny time to pack...

... an' wait out onna porch fer the Rapture.

Gore and his timeline may be wrong, but look at the glaciers they are our biggest indicator.

Ice melts whenever the temperature gets over 32DegF. It can happen for 20 days a year at 33deg or 2 days at 42deg.. Same amount (approx) of melt. Glaciers were doomed before the Industrial Age.

Unless you'd rather have a climate where the glaciers are GROWING? Is that what you want??

Before the Industrial age, was the Little Ice Age. And the glaciers were growing at that time.

Not clear on when CO2 started to become an issue -- but it was WELL after the LIA. And trees found under glacial melt date back to 1600/1700 period. So the dynamics of glacier growing are more involved than you might see them.

Mod Note:

The illegal flaming here is enough to melt glaciers. Do NOT do this again in a Zone2 thread..
