Convinced of what? And who are "we all"?
The rain has stopped, if you mean the succession of posts. That's the theory. Nothing to add except maybe to correct the idea that Norse colonists might have gone to Britain in the mid-3rd millennium: more likely mid-2nd, not that long before the Goidelics came up from Spain.
If it's all too boring for you, don't let me keep you, there are several dozen other threads to read.

Loess is very important and should be critically taken on board by everyone. First question: why isn't it found everywhere?

No, Bernie, I don't have direct evidence that Britain was unpopulated at the beginning of the 3rd millennium. It's a logical conclusion from the theory outlined above: if tidal waves reached a height of 2000 metres in the Atlas Mountains, there would have been no survivors in Britain, where the highest peak I see on the map, Ben Macdui, reaches 1309 metres, nor in Ireland obviously. Exactly when these islands began to be repopulated is a matter of speculation.
Does Stephen Oppenheimer have evidence that Britain was populated 14,000 years ago from the Basque Country? Does it seem logical that people would have migrated from northern Iberia to Britain toward the end of the Ice Age, when the ice reached down to what is now London?
Well, might have been a tourist trip to see the glaciers and they missed the boat back.

Otto Muck's theory, critically commented by Freksa, is that some 5,000,000,000,000,000 (five thousand billion) tonnes of magma was thrown up from the opening along the Mid-Atlantic Ridge, about 2000 by 150 kilometres, produced by the destruction of Atlantis. Most of it fell back into the ocean or directly onto the land, and a part, some 250,000,000,000,000 (250 billion) tonnes in the form of fine volcanic ash, remained in the atmosphere, where carried by the currents it circulated over the lowlands of Europe between Scandinavia and the Alps, and was deposited on the earth over a period of nearly two millennia.
Muck was a missile researcher, an expert in explosive force, who calculated those enormous numbers from studies of the volcanic explosion of Krakatoa in the 1880s.
Answer: Because such a destruction is very, very rare.

He's got a theory about Loess and his name is Muck? You're having a laugh!
And you say that 250 trillion tonnes (only a pedant tries to hang onto the old billion) of fine ash falls to Earth over 2,000 years but doesn't land everywhere? That's even funnier than Herr Muck

A couple of sites that I looked at say that loess is a residue of glaciation, not volcanic at all.

I suppose it's simple - Loess must be the sediment deposited at the bottom of ancient seas? Nothing to do with glaciers or volcanoes.

I'm an Americanadian myself, just trying to make things comprehensible to the locals. In the American system trillion is 9 zeroes, 12 is quadrillion.
Question of where wind currents go. I'm not an expert myself, but I assume Muck knew something about them. Can you provide a more thorough explanation?

Then why isn't it where the glaciation was heaviest?

Is loess found everywhere that ancient marine fossils are found?

Sorry about that. The sites actually say that loess has a tiny granual size, the smallest of any type of soil; that it was originally a residue of glaciation; and that it was subsequently windblown to its present locations.
Now that does seem to me to be a rather fanciful story but nevertheless it seems clear that the geologists are pretty definite that it ain't volcanic. My sense is that we should trust the geologists in this even if we don't trust the geographers.

No, sorry. No fossils. Can't have fossils in wind-blown stuff. That would change the paradigm !

Well, I have to admit that my two previous posts were rather lame. Googling the matter I find that geologists describe loess originating in glaciation and of volcanic origin, as well as from erosion of dunes, desert and playa lakes (don't know exactly what they are: playa means beach in Spanish). This suggests that there are different types of soil having various characteristics in common, which are given the same name.
If you want to argue the sediment of ancient oceans theory, take it up with the geologists, I really don't know.
I'll just google a little more and see what else I can find: like a map of the European loess tongue.
