Hólshraun fissure eruption, Bárðarbunga starting to shake - Iceland *update*
Well sorry folks, looks like we might have another eruption on the way, this one is located under 800m of glacier so if it blows expect another big ashe cloud, hopefully it ends up just as a massive flooding instead.
This volcano's caldera is a massive 70 km area, it has had 2 major eruptions that caused a lot of problems but the last one was in the 1400's.
I read that a potential impact on air travel wouldn't be as big this time because of changed policy and ash cloud prediction. I hope that's the case because I'm supposed to leave for Europe in two weeks.
Correct, they are saying unless this ash cloud if it happens would be unlikely to have the perfect conditions like with Eyjafjallajökull, that ash was very fine so it went much higher into the atmosphere and the prevailing winds were exactly where it was needed to be in order to push it all over the EU. A perfect storm if you will.
Also since I'm reading lots of idiot global warming denial comments in the comments sections of the various news outlets, I wanted to squash the common misconception of how much CO2 eruptions like Eyjafjallajökull contribute to the planet, in 2010 the 5 days of grounded planes in the EU represented a savings of CO2 emissions of 2.8 tons, this is including what the volcano put out into the atmosphere.
Volcano eruptions represent a small % of global CO2 emissions, it requires a massive volcano that erupts for months on end to affect the globe, and that has more to do with ash that blocks out sunlight than gas causing warming, which again deniers seem to ignore.
Our Bombardier Dash 8 is going up in 20 mins to go take a look, the earthquakes continue steadily, so magma is on the move, no sight of it yet but its deep under a glacier so they say it could take a whole day to see evidence of an eruption.
Aren't Volcanos more likely to cause ice ages by blocking sunlight then increase global warming due to CO2 release?
I good me just remembering some bad nat geo doc on the ways to end the world but didn't the yellowstone caldera cause one of the major iceages in the past?
Massive eruptions that last months can cool down the earth because of the Ash cloud which reflects sunlight back into space, but once the cloud dissipates temps return to normal. The volume of CO2 is generally not significant enough to affect long term global climate, it would require a lot of volcano's erupting and for a long time, since the average effect of volcano's yearly is 1/100 of man's CO2 contributions.

I fly to France through London in 18 days If it explodes tomorrow, how long before planes are up again? Should I look at alternate routes?
The 2010 ash cloud went over the continent. There really was no alternate route. I'm in the same spot as I go to Madrid through Frankfurt in 15 days. The last air disruption lasted 6 days.
