While we are on the topic, I have a dumb but genuine question about archaeology. Where does all the extra earth come from on top of things in layers so they have to dig down so much?

Merthyr Tydfil is extraordinary - an entire landscape that we dug up and shipped out wholesale.

A trivial amount, compared to how much of many other countries they burned during the same period.

how many inches of poop did they add

I needed to look up how much 3 inches was. It seems to be 76.2 mm.

We're sinking!

it should be per person rather than per area tbh

I love the units mix. Especially the metric and imperial's one.

But, you didn't use British units.

Well and not to mention this was a completely forested island until charcoal burning became a thing.

No wonder i am a bit shorter than i thought i was ...

That's just coal, we also dug up a bunch of iron, tin, and lead ores, alum, potash, etc. as well as building stone but that's generally heaped back on top somewhere.

And?

christoph: 3 inches... give or take a few decimals. wait, what: they have decimals, this metric contamination of their imperials? 🤔

It's a shame that you have to shift from SI units to inches at the end. 😐

Which is, kinda big, when you think about it.

Of the ~80 mm of UK height lost to the burning of (British bituminous) coal, about 10-20% of ash (by weight) is left behind. So maybe only ~64 mm of UK height has been lost?

P.S. But, yes, as a potential aid to one's imagination in answering "Jeez, how much ore did poor Dickensian blokes with pick axes mine and put in those hoppers on rails and laborously push around, etc?", it's legit to say: "Well, it's like the top 3 inches of all the soil in the UK."

What’s that in installed PV-incident photon depth equivalent?

you have the same with oil, the cheap to extract reserves are gradually getting used up, leaving the more expensive in the reserves.

Or about 200 feet of my home village

The calculation I want to see is acre-years of plant growth per gallon of gas, and then per mile (or per tankful).

Good. That will balance the increasing numbers of people, many of whom really should know better, attempting to rehabilitate her reputation.

Spoken like a true Tory. It wasn’t most. It was those in already well paid managerial/clerical roles that made out well. The reality was thousands thrust into unemployment with little to no skills to find work elsewhere. Most miners left school at 16 and went down pit.

Thank you for the info. As an unlearned American, the first things that come to my mind in regard to these matters are the rapid evolution of a species of butterfly to go from white to black, Billy Elliot, and that excellent EP from Chumbawamba released upon the occasion of her death.

That's an Americanism. We don't say "deez nuts", we say "deez pork scratchings".

They didn't burn the soil, just moved it.

Those rabbits are still very bitter about the whole thing, too. Their warren now has disproportionate rates of drug use and unemployment. Gun crime is only kept low by the fact that if you point a gun at a bunny, he sticks his finger in the barrel so that it blows up in your face.

I thought of Jasper Fforde as well. Reminiscent of his recent-ish novel The Constant Rabbit.
