I thought the hexagon thing (even if a bit off) was a genuine legit science question that should not be ridiculed. The answer, as Noah says, is that it's the Antaractic and to a lesser degree, Greenland ice, not the floating ice, that will be the problem, of course.
Plus he doesn't even understand Archimedes' Principle. Total fail.
True. But a lot of people don't know that, and I've found that, even when ppl might be commenting in bad faith, it helps to explain earnestly (as if in resp to legit questions--which they might be, even if some ppl might just be more boorish) than to ridicule.
Let's use a two-pronged approach. You explain earnestly, I'll ridicule (and then explain earnestly). Together we can't fail!
Where did the hexagon thing come from? (and how could it possibly matter?)
I think he means that ice has greater volume than water because it's a crystal lattice instead of a fluid. That is correct but irrelevant.
Oh right. I thought that he thought the macro structure of ice was a hexagon.
Melting sea ice does slightly raise sea level, because the resulting fresh water is slightly less dense than sea water.
You deny the power of the hexagon??!!
I think the biggest cause of sea level rise is the thermal expansion of water.
Omg. Thank you!
All you have to realize is that ice floats and isn’t completely submerged, so some of its mass is above water it maintains an equilibrium with the water it’s in, unless forcibly submerged.
I'm one of those re-tweets:https://twitter.com/Koba_Gold/status/1051978866095316992?s=19 …
Also very significant is that liquid water is densest at ~4°C, so the oceans themselves expand as they warm. Even if there weren't any ice at all, sea level would rise due to thermal expansion.
Well said that man. But your first tweet is delightfully focussed.
Oh yeah? Well if it’s on land then how’s it going to get in the oceans, Mr. Smarty Pants?!?!
I think I can help here: Due to a magical process called physics, warmer water expands and takes up more space. This is called "thermal expansion." Ice melting, whether on land or in the sea, takes up more space. Some background: https://www.ipcc.ch/ipccreports/tar/wg1/411.htm … http://cosee.umaine.edu/cfuser/resources/tr_sea_level.pdf …
We're already seeing the results. It's not just happening in 12 years, or by 2050, or 2100. It's happening NOW. Here, we looked at seven places around the globe where climate-related sea level rise &/or extreme rainfall have led to catastrophic flooding: https://orbmedia.org/stories/under-water/ …
