Professor Ian Plimer could not have said it better! If you've read his book you will agree, this is a good summary.


Where Does the Carbon Dioxide Really Come From?


PLIMER: "Okay, here's the bombshell. The volcanic eruption in Iceland recently . Since its first spewing of volcanic ash , in just FOUR DAYS, NEGATED EVERY SINGLE EFFORT you have made in the past five years to control CO2 emissions on our planet - all of you.

Of course, you know about this evil carbon dioxide that we are trying to suppress - it’s that vital chemical compound that every plant requires to live and grow and to synthesize into oxygen for us humans and all animal life on this planet.

I know....it's very disheartening to realize that all of the carbon emission savings you have accomplished while suffering the inconvenience and expense of driving Prius hybrids, buying fabric grocery bags, sitting up till midnight to finish your kids "The Green Revolution" science project, throwing out all of your non-green cleaning supplies, using only two squares of toilet paper, putting a brick in your toilet tank reservoir, selling your SUV and speedboat, vacationing at home instead of abroad!!!

Nearly getting hit every day on your bicycle, replacing all of your 50 cent light bulbs with $10.00 light bulbs.....well, all of those things you have done have all gone down the tubes in just four days. The volcanic ash emitted into the Earth's atmosphere in just four days - yes, FOUR DAYS - by that volcano in Iceland has totally erased every single effort you have made to reduce the evil beast, carbon. And there are around 200 active volcanoes on the planet spewing out this crud into the atmosphere - EVERY DAY of the year.

I don't really want to rain on your parade too much, but I should mention that when the volcano Mt Pinatubo erupted in the Philippines in 1991, it spewed out more greenhouse gases into the atmosphere than the entire human race had emitted in all its years on earth.

Yes, folks, Mt Pinatubo was active for over one year - think about it. Of course, I shouldn't spoil this 'touchy-feely tree-hugging' moment and mention the effect of solar and cosmic activity and the well-recognized 800-year global heating and cooling cycle, which keeps happening despite our completely insignificant efforts to affect climate change.

And I do wish I had a silver lining to this volcanic ash cloud, but the fact of the matter is that the bush fire season across the western USA and Australia this year alone will negate your efforts to reduce carbon in our world for the next two to three years. And it happens every year.

Just remember that your government just tried to impose a whopping carbon tax on you, on the basis of the bogus 'human-caused' climate-change scenario. Hey, isn’t it interesting how they don’t mention 'Global Warming' anymore, but just 'Climate Change' - you know why? It’s because the planet has COOLED by 0.7 degrees in the past century and these global warming ‘BS’ artists got caught with their pants down.
And, just keep in mind that you might yet have an Emissions Trading Scheme - that whopping new tax – imposed on you, that will achieve absolutely nothing except make you poorer.

It won’t stop any volcanoes from erupting, that’s for sure!!!

But, hey, relax...... and have a nice day mate !"
As Ant says, the rambling bollocks of someone with a vested interest in attempting to squash climate science.

Unfortunately....

Volcanic versus anthropogenic CO2 emissions

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 a projected 35 billion metric tons (gigatons) of CO2 emissions in 2010 (Friedlingstein et al., 2010), release an amount of CO2 that dwarfs the annual CO2 emissions of all the world’s degassing subaerial and submarine volcanoes (Gerlach, 2011).

The published estimates of the global CO2 emission rate for all degassing subaerial (on land) and submarine volcanoes lie in a range from 0.13 gigaton to 0.44 gigaton per year (Gerlach, 1991; Varekamp et al., 1992; Allard, 1992; Sano and Williams, 1996; Marty and Tolstikhin, 1998). The preferred global estimates of the authors of these studies range from about 0.15 to 0.26 gigaton per year. The 35-gigaton projected anthropogenic CO2 emission for 2010 is about 80 to 270 times larger than the respective maximum and minimum annual global volcanic CO2 emission estimates. It is 135 times larger than the highest preferred global volcanic CO2 estimate of 0.26 gigaton per year (Marty and Tolstikhin, 1998).

In recent times, about 70 volcanoes are normally active each year on the Earth’s subaerial terrain. One of these is Kīlauea volcano in Hawaii, which has an annual baseline CO2 output of about 0.0031 gigatons per year [Gerlach et al., 2002]. It would take a huge addition of volcanoes to the subaerial landscape—the equivalent of an extra 11,200 Kīlauea volcanoes—to scale up the global volcanic CO2 emission rate to the anthropogenic CO2 emission rate. Similarly, scaling up the volcanic rate to the current anthropogenic rate by adding more submarine volcanoes would require an addition of about 360 more mid-ocean ridge systems to the sea floor, based on mid-ocean ridge CO2 estimates of Marty and Tolstikhin (1998).

There continues to be efforts to reduce uncertainties and improve estimates of present-day global volcanic CO2 emissions, but there is little doubt among volcanic gas scientists that the anthropogenic CO2 emissions dwarf global volcanic CO2 emissions.

And you remember the one that closed down European airspace?

Iceland's Eyjafjoell volcano is emitting between 150,000 and 300,000 tonnes of carbon dioxide (CO2) per day, a figure placing it in the same emissions league as a small-to-medium European economy, experts said on Monday.

Assuming the composition of gas to be the same as in an earlier eruption on an adjacent volcano, "the CO2 flux of Eyjafjoell would be 150,000 tonnes per day," Colin Macpherson, an Earth scientist at Britain's University of Durham, said in an email.

Patrick Allard of the Paris Institute for Global Physics (IPGP) gave what he described as a "top-range" estimate of 300,000 tonnes per day.

Both insisted that these were only approximate estimates.

Extrapolated over a year, the emissions would place the volcano 47th to 75th in the world table of emitters on a country-by-country basis, according to a database at the World Resources Institute (WRI), which tracks environment and sustainable development.

A 47th ranking would place it above Austria, Belarus, Portugal, Ireland, Finland, Bulgaria, Sweden, Denmark and Switzerland, according to this list, which relates to 2005.

Experts stressed that the volcano contributed just a tiny amount – less than a third of one percentage point – of global emissions of greenhouse gases.

So I call bollocks on Mr. Plimer.
