Yes, we all know about ice, but question was “will it add anything to sea levels”.
I think answer is no. Won’t add anything.
I agree that in the normal cycle of evaporation and rainfall, it won't affect sea levels as it is a closed loop. I wasn't disagreeing with you. I think answer is no. Won’t add anything.
I was just adding the caveat that water locked into ice was outside of the normal cycle.

15mm is bugger all in drainage terms. I'd expect most to be taken up by the soil etc.
Yup. And also worth noting that flash flooding usually occurs when the rainfall rapidly exceeds the capacity of the soil and flora, and drainage, so you get immediate runoff instead.Edited by Clockwork Cupcake on Sunday 22 December 15:42
What diameter circle do you have to walk around for a compass to point at the north/south pole with a hand held magnetic compass? I assume its not like 2/3ft away from the center of the north pole, and not as far as having to be 200miles away? But what is the distance where you can see the needle move around so that's it's always pointing to the center point of the north/south pole ?

It's the magnetic pole the compass points to. Exige77 said:

It’s the same water being constantly recycled, evaporated, rain, drain off back to sea, rinse & repeat.
Which is why landfill seems reasonable. Dig up stuff, make stuff, throw stuff in hole you made when it is finished with. It’s the same water being constantly recycled, evaporated, rain, drain off back to sea, rinse & repeat.

Unless it gets locked up in permanent ice, as that takes it out of the cycle
That's why sea levels are rising as the permanent ice caps melt, which releases water back into the cycle.
Sea levels also rise as glaciers are not 're-stocked' with snow that turns to ice so much now, and the sea level will rise anyway as the water gets warmer.That's why sea levels are rising as the permanent ice caps melt, which releases water back into the cycle.
Recording an album - how many outtakes and alternate versions are locked away in the vaults after a recording session? I ask as an old sod who's bought many 'expanded re-issues' for the groups I've followed over the years. I heard one quote from a producer, referring to a specific album, that as well as the released version there were at least two other complete alternate versions of the album locked away.

Yes, all the time but it's a drop in the ocean because there are so many of them. It also depends where they are based because some countries leave them alone if they don't target locally.Microsoft scam

Why are Stack instruments so named?
And Momo, now that I think of it.
They are both the names of the respective companies. And Momo, now that I think of it.
In the case of Momo (or, more correctly, MOMO) it stands for MORETTI-MONZA and was founded by Giampiero Moretti

But what is the distance where you can see the needle move around so that's it's always pointing to the center point of the north/south pole ?
A compass aligns with the earth's magnetic lines of force. Anywhere near the poles these are pretty much vertical so a hand-held compass wouldn't work at all; the needle would tilt too much and jam against the housing, and the bearing wouldn't work if you held it sideways.A floating-ball type marine compass might work better but as you moved away from a pole it would still point down to a point well below the earth's surface near to the iron core. So I guess the answer is "as far away as your eyesight is good enough to tell that a free-floating magnet isn't quite vertical".
BTW good hand compasses are designed to allow for the "angle of dip" of the earth's field, which is only horizontal near the equator.
This is the underneath of my orienteering thumb-compass:
The pointer-bit you navigate by (white) is just a strip of light plastic. Glued to it is a tiny neodymium magnet (black). This reduces the angular momentum so it settles instantly and more accurately compared to a traditional magnetised iron needle,. Note that the magnet is slightly offset to the south-pointing side, and there's also a tiny counterweight. These help it balance horizontally in most northern-hemisphere countries. You can also get equatorial and southern-hemisphere versions.
How does the energy in a mace work vs a hammer or maul? Namely how you can seemingly greatly imcrease the end force by simply adding a flick of the wrist to your tool/weapon just before impact.
There's no free energy, so how does such a small wrist movement make such a difference compared to what you'd manage woth no wrist/joint.

I failed physics, but basically you are increasing the length from the fulcrum (your wrist) thereby increasing the amount of travel at the end which is travelling faster because it's further away from your wrist. Same principle as a differential on a car. Inside wheel travelling less distance than outer wheel, etc.There's no free energy, so how does such a small wrist movement make such a difference compared to what you'd manage woth no wrist/joint.
