Volcanic Ash is now heat seeking
According to Olivia Wirth on the radio this morning, Propeller Aircraft are less susceptible to Volcanic Ash encounters than Jet engines because Jet engines are hotter and the Volcanic Ash is attracted to the heat in the engine.
Wow has she considered teaching Aeronautics at University, she is so smart.

Just read through my old science text books and it turns out it's a similar physics theory as to why her head repels hair brushes.
My money is on this thread being locked by dinner time.

I thought I might watch parliament this afternoon for some light entertainment, and to see what sort of carbon tax this volcano will have to pay, but alas the entertainment was too light and the volcano seems to have escaped any penalty. As for Olivia, I keep asking exactly whose niece is she?

thats what she said.
Where did you pull that figure from?
From Volcanic Gases and Climate Change Overview

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 greater than 130 times more CO2 annually than all the world’s degassing subaerial and submarine volcanoes (Gerlach, 2011).

Hi Stew
It was in a piece I read on Krakatoa many years back. It indicated that the eruption of Krakatoa spewed more CO2 into the air than the entire emissions of man since we started lighting fires as cavemen. Can't talk to its accuracy, but it went on to talk about the "average eruption" etc.
Looks like the scientists can't agree on anything.
UPDATE- Just found it. An online posting from a professor - Looks like I got the volcano wrong, but the sentiments are the same.
Professor Ian Pilmer – Professor of Mining Geology, University of Adelaide and noted author:
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 its entire 40 MILLION YEARS on earth. Yes folks, Mt Pinatubo was active for over one year - think about it.

The problem with facts.. sigh, from the US Geological Survey talking about the emissions of Volcanic eruptions averaged over the last 2000 years QUOTE
How many times do I need to 
because of vested interest people scared of losing jobs over their high carbon generating jobs.
This seems like a huge amount of CO2, but a visit to the U.S. Department of Energy's Carbon Dioxide Information Analysis Center (CDIAC) website (Carbon Dioxide Information Analysis Center) helps anyone armed with a handheld calculator and a high school chemistry text put the volcanic CO2 tally into perspective. Because while 200 million tonnes of CO2 is large, the global fossil fuel CO2 emissions for 2003 tipped the scales at 26.8 billion tonnes. Thus, not only does volcanic CO2 not dwarf that of human activity, it actually comprises less than 1 percent of that value.

Can this be true? There are 6.7 billion people on earth. Therefore the average fossil fuel consumption must be 4 tons per person per year. This would be equivalent to ~4700 L of diesel... Damn, all those underdeveloped countries must be driving miles... or could this be another example of creative accounting on the part of the green loonies ('cos they actually have NO idea how much comes from volcanoes 'cos most have never been measured and we don't even know how many there are)?
Cheers

I think the correct numbers are around 35 billion tonnes produced by human activities in total of which fossil fuel usage accounts for around 8 billion tonnes.
Pilmer refers to greenhouse gas emmisions (includes CFC etc) whilst the USGS refers to CO2 emmisions only.

Co2 emissions
Has anyone bothered to consider that even if Australia were to close down every single Co2 emitting piece of equipment we would have, at absolute best, less than 2% of Global emission reduction. How in hell's name will putting a tax on Co2, aimed at reducing Australia's 2000 emission level by 5%, have any measurable impact on TOTAL GLOBAL EMISSIONS? This tax is just another Millennium Bug type sham. If our incompetent government were in any way really wanting to reduce global emissions they would stop exporting coal to some of the worlds leading polluters. We keep hearing that we are, per capita, the highest polluters in the world. So what, we still contribute less than 2% of TOTAL GLOBAL EMISSIONS. Carbon Tax equals a hit to the wallet, that is all.
