For several days now, many European airports are closed. As the weather was beautiful, one wonders why, of course, you do not see this huge cloud of ash?
The cloud is located at 6-11 km altitude and because Iceland is just a piece of Germany, the cloud has thinned . Solely a barely visible light opacity of the sky bears witness to be present from her.
The sunset, however, is stronger than usual in the red colorless, as the starch particles absorb the blue light. So just now watching the night sky.
What you see now on the other hand can be a sky without contrails and virtually no noise. Only the planes fly by visual flight may continue in the air.
For environmental it seems to be good bloggers on informationisbeautiful.net calculated that 344 109 tonnes of CO2 emissions by 206 465 tonnes per day is saved by the ban. The volcano itself is also not environmentally neutral, and costs around 15,000 tons per day to book. Questionable is natural as the klimschädigend (Auto/Bahn/Schiff-) Traffic ist, da er gerade durch das Flugverbot entsteht.
