Perhaps volcano eruptions are the answer to saving the environment from manmade pollution?





The eruption of the Eyjafjallajokull volcano is unlikely to have any significant impact on climate but has caused a small fall in carbon emissions, experts say.



Although large eruptions such as Mount Pinatubo in 1991 can spew out enough material to shade and cool the planet, recent activity in Iceland is very small in comparison. The ash cloud has not reached the high atmosphere, where it would have the most effect, and it contains little sulphur, which forms reflective droplets of sulphuric acid. The World Meteorological Organisation in Geneva says any cooling effect from Eyjafjallajokull will be "very insignificant".



A larger effect on the atmosphere, though still small in global terms, comes from the mass-grounding of European flights over the past few days. According to the Environmental Transport Association, by the end of today the flight ban will have prevented the emission of some 2.8m tonnes of carbon dioxide since the first flights were grounded.



The volcanic eruption has released carbon dioxide, but the amount is dwarfed by the savings. Based on readings taken by scientists during the first phase of Eyjafjallajokull activity last month, the website Information is Beautiful calculated the volcano has emitted about 15,000 tonnes of CO2 each day. Worldwide, the US Geological Survey says volcanoes produce about 200m tonnes of carbon dioxide every year.

I didn't follow the link to read the full story, but did they take into account the extra car emissions from people who drove because they couldn't fly?

Car journeys still generate less carbon per person than air-planes http://driving.drive-alive.co.uk/rel..._emissions.htm

That was very informative Mr. Falafel, and to share my experience I was due to travel but then the eruption of Mt. Eyjafjallajokull has interrupted air travel again. The volcano re-erupted and a change of winds induced an ash cloud to prevent air travel again. Thankfully for travelers this time around it was only overnight and not for days. There's chatter that this volcano may erupt all over again, leading to delays in airline travel yet again. If it is in any way feasible, I would advise not flying into any regions suffering from this volcano until it is certain that there won't be any more activity with the volcano.
