volcanic cloud stopping flights....

[R1Geezer]

Got me thinking that there are thousands of volcanoes all over the world, some of them errupting continually, eg son of Krakatoa has basically built a new Island where the old one was and Hawaii erupts non stop to mention a couple. Now correct me if I'm wrong but I'd imagine that just a teensy weesny bit of CO2 is pumped into the atmosphere from all those volcanoes. So how much contribution to global warming to you think the volcaloes are making? How does that compare to mankind? As this particular eruption has in fact stopped flying presumably that's beneficial!

by and large volcanoes don't erupt all that much; it's usually headline news when it happens, as now. I don't know how much it compares with farting cows.

apart from the ones that erupt 24 hours a day every day.

Volcanoes emit around 0.3 billion tonnes of CO2 per year. This is about 1% of human CO2 emissions which is around 29 billion tonnes per year.

This is the first time I have known it to prevent flying.

Can anyone tell me when it has happened before?

There have been a number of events affecting planes

Fortunately in the UK we are a long way from most active volcanos so it's rare that such events affect us directly

Apparently, Cows burp methane (a much more Green house gas) not CO2.

I heard the dust cloud was down to the guy cleaning out the trophy room at The Emirates??
