NEW UPDATE: When this first posted, I used a graphic from Information is Beautiful which compared Co2 emitted by the unpronounceable volcano to the Co2 not being emitted by grounded airplanes. My first update corrected their info, and this update corrects their graphic. Also, the NYT has tried to let us know how to pronounce "Eyjafjallajokull" using this guide:
- “Eyja” is the Icelandic word for island
- “Fjalla” means mountain
- “Jokull” is glacier
Icelandic sticks a few t and g sounds in there, so just say: Hey-ya, fergot ya, Yokel!
Amazing animation from ZH shows the swirling volcano plume covering Northern Europe, spreading to Russia, and spiraling backwards towards Newfoundland. We probably all know people stranded in Europe, waiting to get out - or trying to return. A friend looking for opportunities in Sierre Leone just got back to London before flights shut down. Another friend was flying back from a vacation in Ireland as the volcano erupted, and could see it from the left side of the airplane. Lucky timing. Eurocontrol has updates. Apparently if you can make it to Rome or other Club Med cities, you have a chance of flying home.
Troubling implications from this. Everyone thinks this blows over quickly. What happens if this eruption continues for 13 months, as the last eruption (in 1822) did? Lufthansa sent 10 jumbo jets up to see what the effects would be, and found no harm. KLM is also reported to be testing flights near the ash layer, to see if it is thin enough to allow flights to recommence. If not, routes have to be reconfigured and the economic dislocation will mount.
Curiously, while this should cool the planet if it continues due to putting aerosols in the upper atmosphere, it is also reducing Co2 emissions! Volcanoes do put out a lot of Co2, but planes over Europe put out more. Original chart from Information is Beautiful, updated chart here:
UPDATE 4/20: The original chart above turns out to be misleading. The small pyramid above should be increased to be about the size of the inverted pyramid of saved emissions. It is still less than total Euro airplane emissions, although note that that many planes around the Club Med part of Europe are still flying.
The estimate of Co2 is too low by an order of magnitude: estimates from the UK place it at between 150,000 and 300,000 tonnes/day, not the original chart's 15,000, based on a prior eruption in Iceland. (A metric tonne is very close to the same as a British ton and slightly larger than a US ton.)
To put these Co2 amount in perspective, the Herald Sun in Australia commented it is more than the Rudd government is trying to save in carbon limits. Australia emits around 400M tonnes a year, or a little over 1M tonnes/day, meaning the volcano is spewing about 1/4 of Australian emissions a day.
