Not Volcanism, the Aberdeen slime from years of BrillCream wearing 1970s Oilmen, gets everywhere, at its worst in Dyce.
Unfortunately, I got to work before it all closed down. 
UK Airspace closed... anyone watching the news?

Flights
I had not realised all those Sleezly Jets etc coming over Chi throttling back for the Gatwick approach caused so much background noise - it has been remarkably peaceful and the Sky clear of contrails.
I suspect Slezzy and Ryan do not want expensive engines getting worn out hence not flying till after weekend whatever NATs advise - service and customer care in times of disruption being the last item on the agenda for their business models.

Or you could do like FlyBE did yesterday evening... 6.30pm they announced a bunch of flights thtat they woudl be putting on.. from manchester, Newcastle, Glasgow, Belfast.... and encouraging peeps to buy tickets.... then at 6.30 this am they cancelled all the flights!
I think that Ryanair etal are being a lot more realistic and looking at the forecasts.. instead of dicking people around like FlyBE.

Dunno Geoff! But thats what they keep saying.... on the telly of course! Most of this stuff apparently has the consistency of fine talcum powder, so it might not be coming down so fast, a bit like fog or mist. We experienced a severe Saharan duststorm on Lanzarote a few years back, which carried right across the atlantic to Brazil - and sand is pretty heavy too! But it didnt seem to worry the likes of Ryanair and Squeezyjet in the way this stuff does. The Saharan dust was incredibly fine, but apparently not very high in the atmosphere. Perhaps thats why the airlines were unworried.
Yes Ubergeekian, I know controlled airspace is much higher, and the logistics of sorting it out could take longer than the ash cloud hopefully wil last, but they COULD get a few flights in under it.

Sahara dust is old and is very rounded. That is why it makes such poor concrete.
The brand new stuff coming out of a Volcano is quite sharp.
Also it comes out hot and heats the air, so rises. It forms a small low pressure system. As long as it stays in a rising air mass it takes longer to come down.
After a short walk up here, the sky looks like off Africa with a tinge of colour to the horizon and absolutely no trails. It is quite wonderful.
With no moisture around here, there is no condensation on the particles to help make them fall. Even ash that is created in water areas floats as it is like aero chocolate.
Still worried about Tues/Wed.

Air crash
If you owned a plane would you go flying right now?

Hate to say... we expect to see several fatal private aviation crashes at this time of year... I keyed up the weekend staff for this on Friday.... Not much flying in the winter..
first nice weekend in the spring a couple of Pipers plant themselves into hillsides every year.
I would be Gobsmacked if this was even remotely connected with Volcanicity.

With all this ash in the air forming a barrier to the Sun, does that mean we can forget about global warming now?

Yes,for a few months in one region.

Is it absorbing more sun energy or reflecting more? When it falls, is it landing on something more reflective or less. At night is it absorbing the outward heat?
If the pressure systems change and it all lands on Greenland/Polar regions the long term story could be quite different.
Late addition: One of the advanced forecasts this year, did qualify the outcome on if there was no significant volcanic activity.

Volcanos and contrails
After Krakatoa was there not a very cold year due to the atmospheric dust cloud? Seem to remember reading that it caused crop failures and a min-ice age for a year or two. It was partly the dust and partly the sulphur oxides I think.
After 9/11 when all US airspace was closed for a few days there was a measurable change in the weather caused by the lack of contrails.

This is minuscule compared with Krakatoa, which itself wasn't that big; it simply happened to be the first big eruption to force itself on the notice of the world at large. Volcanic effects had been seen before, but the cause was not known because of limited global communications. Mount Agung and the Laki eruptions are the ones to look at for biggies! And in all cases, the effects are local and short-lived - one or two years.

No, but if we discovered we didn't actually need air travel then we probably could forget about it ;-)

So we really need Yellowstone Park to erupt then?
I don't need air travel Boo2. I can sail anywhere I want to go.

Aha! Another one not in a hurry.........
Yeah, that's me. If the wind drops, get out of the channel, drop the hook, and have a cup of tea. The World will still be there when I have finished.
