Aye that volcano will have chucked more gases into the air than anything Brown will have done to help the enviroment.
Going to be interesting how long this thing is going to last.
The amount of ash thats up there already is quite small but the thing doesn't seem to be running out of steam. The ash is also up there before summer so next winter could be a right freezing job. If that high pushes the ash up into the artic high and dumps it on the ice cap that could speed up its melting. So the flights getting grounded for a week might be the least of our worries.
