Wet clothes appear darker because the water refracts some of the light that falls on them, so less of it is reflected towards your eyes. It's not that it changes the color of the cloth per se: it really is just dimmer.

The adverb "well" is related to "will".

'Arse-ropes' is an obsolete word for the intestines, and can be found in Wycliffe's translation of the Bible.

I assumed that was a joke, because reversing a familiar saying for comic effect seemed too modern for Thomas More, or at least too unserious for him. Then I wondered how old the saying was, so I looked it up, and discovered More was the first person to use it in English, at least as far as we know. Which either Terry knew, or is one hell of a coincidence.

I knew that St Thomas had coined it, that's all.

Which is more than the rest of us knew, I suspect. Until now.

When you do a search on the forum for the word "quote", it gives you all the posts that contain quoted posts, because see, the BBCode for quote tags contains the word "quote". Isn't PB marvelous?
... okay, to be fair or at least whataboutist about it, I've just tried it and the search feature of LD behaves the same way. Excluding BBCode from searches would probably only take a few lines of codes, but either they didn't notice the bug or CBB'd to fix it, but my money's on the former.

LD let you search for 'quote' on its own, and didn't tell you it was too short or too common?

Surprisingly, it didn't.

I didn't really know how the greenhouse effect worked. I knew it had something to do with absorption somehow, but now I realize I didn't know how it fit into the bigger picture. For one thing, I thought greenhouse gases absorbed sunlight (i.e. radiation of certain wavelengths coming directly from the sun), but nope, they absorb some of the infrared that Earth's surface radiates. Like all bodies that are heated up, the Earth tries to get back to thermal equilibrium by radiating some of the heat in the form of infrared radiation back into space; what causes global warming is that since greenhouse gases absorb some of that infrared light, Earth loses some of its capacity to evacuate the heat.
It's not just that greenhouse gases absorb heat and function as some sort of heater or hot watter bottle: it's that they prevent the heat from being radiated back into space, and that the only way for Earth to get back to equilibrium (i.e. to radiate as much energy as it receives from the sun, 240 W/m² on average) is to warm up, because hotter bodies radiate more energy than cooler ones. Global warming is about Earth trying to clear its energical debt: what goes out must equal what went it, and the only variable of adjustment is its temperature.
(thankfully the universe isn't greedy: zero interest-rate!)

Here's the culprit by the way (in French):
A physicist turned educational YouTuber that I really like. In this video he discusses a more technical issue: why adding more greenhouse gases to the atmosphere will increase Earth's temperature even more, when it was previously thought that there was a limit to this phenomenon. He also provides very good evidence that climate science is, in fact, science: a theoretical prediction was that, given our understanding of the complex mechanisms involved in global warming (namely, how different layers of the atmosphere all absorb and radiate back some of the infrared radiation coming from the earth), a certain layer of the atmosphere should in fact be cooling down in the process, which was experimentally confirmed after the paper which made this prediction was published.
