I was reading the comments on another forum where there are a large percentage of English and European responders. One of the comments caught my eye. It seems the air in England and northern Europe is extremely clear even though the volcano is spitting stuff out. The visible portion of the plume seems to be going north of England and in the direction of Norway.
Several people have commented on how clear the sky is and are attributing that to the fact no airplanes are flying. And so they are rather glad the airports are shut down because their air is so much cleaner. Don't they realize that volcano will spit more garbage into the sky in one day the one year of airplanes flying?
And nobody that I have found has asked what is the carbon footprint of the volcano.
Al Gore: "What? Volcanoes have a carbon footprint? We must regulate them!"
