Volcanic Eruptions and CO2 Emissions

http://www.guardian.co.uk/environment/blog/2010/apr/21/iceland-volcano-climate-sceptics

Along with the ash and lava, there have been many interesting asides tossed into the air for our consideration by the Eyjafjallajokull volcano. We have noticed just how reliant our globalised systems are on air travel. We have been reminded of nature's brute force and primordial beauty. ....But one opportunity the volcano has gifted us in particular is the chance to put to bed once and for all that barrel-aged climate sceptic canard which maintains that volcanoes emit far more carbon dioxide than anthropogenic sources.....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 , deniers, this argument won't fly.

The eruption of a volcano on Iceland is threatening to turn into a major headache for businesses across Europe and around the world as a spreading ash cloud closes more European airports.  Airlines are already counting the cost of grounded planes, and there are growing fears about the transportation of food supplies and other essential goods should the flight disruptions persist for several days — or longer.

Another argument in favour of local food!
