A comment on Antarctic ice cliffs may not contribute to sea-level rise as much as predicted. Parent comment

I remember in middle school (~2004) in Cambridge we had a school assembly about global warming, and they showed an animation of a cup of water filled with ice, the ice melting, and then the cup overflowing.

In retrospect it was a simplified analogy for kids to understand, but on the other hand, massive ammunition for climate skeptics such as my parents who instantly debunked the analogy as soon as I told them about the assembly and put a cup of ice water on the kitchen table to show how silly the claim was.

That analogy may hold for arctic ice, but not antarctic ice, which is mostly a set of glacier's above the ground - some of it even has its base more than a mile above sea level.

So think of a full cup and dropping ice cubes into it. Totally different result.

Sure, but even now the analogy is not great because the melting part has nothing to do with it.

In other words, if you drop an ice cube into a cup of water, it will either immediately overflow or it will never overflow. The melting part has nothing to do with whether it will overflow. If the snow on the roof melts -> the cup overflows

I think a better analogy is a cup sitting at the drain pipe of a rain gutter and the roof is covered with snow.

I think you missed a word in my comment.... "a full cup".

No I understood, but at that point it doesn't matter if it is ice or not. You could drop rocks into a full cup and it would overflow

Ahhh - now I see what you mean. Yes, that's a better analogy.

Good point, don’t forget same is true of Greenland’s glaciers.

You may want to check your blocking software or company firewall.

Works fine on my person device running ABP ( I just double checked to make sure).

If you want to simulate Greenland/Antarctica, you have to put the ice cubes outside the cup, and have them drain into the already full cup as they melt.
