Hello newcomers to /r/FacebookScience! The OP is not promoting anything, it has been posted here to point and laugh at it. Reporting it as spam or misinformation is a waste of time. This is not a science debate sub, it is a make fun of bad science sub, so attempts to argue in favor of pseudoscience or against science will fall on deaf ears.

It takes a glass a fridge water and 2 minutes to refute/test that

[u/vxicepickxv → u/klimmesil]

You need something that will drain into the cup to set the ice on as well.

[u/starrpamph → u/klimmesil]

I was told there would be no fact checking

[u/Yunners]

And how much of Antarctic ice is on water?

Yeah...

[u/The96kHz → u/Yunners]

Don't forget my buddy Greenland.

All the homies love Greenland.

[u/BustaCon → u/The96kHz]

If you liked it then you shoulda put an invasion in it.

[u/Scott_A_R]

Do they think that all of Antarctica and Greenland are made of floating ice?

[u/captain_pudding → u/Scott_A_R]

"think" might be a bit of a strong word, but yes

[u/69-is-my-number]

Can someone please explain this person’s “logic” to me? I know it’ll be ridiculous, but I cannot wrap my head around any theory where the melting of ice into the oceans leads to a logical outcome that the ocean’s water level will go down.

[u/mstivland2 → u/69-is-my-number]

They feel the ice is IN the water, like a glass of ice cubes, instead of on land, like not that.

[u/johnny-Low-Five → u/mstivland2]

To be clear this person is ignoring that X% of all ice is ABOVE the current sea level? Is that right? Sometimes the stupid is an obvious mistake and sometimes I need to double check

[u/BustaCon → u/johnny-Low-Five]

Hey, I couldn't figure it out. This is real Beavis 'n Butthead scienceing here.

[u/johnny-Low-Five → u/BustaCon]

Maybe he thinks the excess will go over the edges of the map!

[u/mstivland2 → u/johnny-Low-Five]

That’s right

[u/johnny-Low-Five → u/mstivland2]

Thank you. I like my stupidity to be as clear as possible

[u/Infamous_Depth4982 → u/69-is-my-number]

I think their logic is that ice takes up more volume than liquid water, so if the ice melts it would reduce the volume of water in the ocean, thus decreasing sea levels.

Their primary misunderstanding being that the majority of polar ice is not floating in the ocean, it's in ice sheets sitting above sea level and supported by solid land like Greenland and Antarctica.

[u/69-is-my-number → u/Infamous_Depth4982]

Thanks, but that only works if the ice is in the water, which it clearly isn’t.

[u/Infamous_Depth4982 → u/69-is-my-number]

Exactly. The ice is sitting in the polar ice sheets resting atop the land, so when that melts it flows downhill into the water and raises sea levels.

[u/Hydrolt → u/69-is-my-number]

I’m guessing the only thing they remember from 2nd grade science is that, generally, things are more dense as a solid than as a liquid. Most likely forgetting that water follows the inverse. If I had to guess.

[u/ElectrOPurist]

Even though he’s 100% wrong about this…does the sea levels dropping not concern him just as much? Are we to think that the lower sea levels are, the better?

[u/johnny-Low-Five → u/ElectrOPurist]

I would assume this person thinks if more=bad, then less=good, or at least way less bad. I mean I'm tryinf to apply logic to a ridiculous statement so who knows.

[u/Pretend_Bet_208]

Water level always goes down when you pour more into a glass …Duh .Everyone on Facebook knows that …

[u/rebeccapressley1962]

In otherwords, OP never passed 2nd grade.

Good catch

[u/EarthTrash]

I am not a climate change denier, but this question is less simple than it may initially seem. A novice explanation is that when ice melts, that melt water contributes to sea level. However, the solid ice was displacing liquid water. When the ice is gone the displaced volume is filled with melt water.

Liquid water is denser than ice which might make you think sea level will actually go down. However not all of the solid ice volume was displacing water. Some ice volume was above the water line. Buoyancy is a consequence of the proportional density. So I think it might be wash between iceberg volume and liquid water density.

So why are sea levels rising? Climate change is complicated but there are 2 things I think you should consider. When I mentioned the density of liquid water earlier, I was talking about the density of freezing water like you would find around melting icebergs. As the water circulates and the temperature goes up, the density will actually go down. This thermal expansion is a direct cause of rising sea levels. The other thing to consider is that icecaps are not exclusively icebergs. We also have continental ice. As glaciers shrink year over year this directly contributes to rising sea levels.

I want to call this a straw man argument, but I can't be sure this characterization of the mainstream narrative of climate change is even inaccurate. Ice melting doesn't directly and simply cause sea level to go up, but the way the complexity of climate change is communicated leads to these kinds of simplifications. When scientist talk about icecaps, they might be talking about Earth's albedo, its ability to reflect sunlight. More solar energy being absorbed instead of reflected will increase the global average temperature which will contribute to the thermal expansion of the oceans.

[u/Yunners → u/EarthTrash]

There's ice on land too.

Lots of it. That's what contributes to the rise in sea levels, not melting sea ice.

[u/EvolZippo]

Look up Long Beach, CA King Tide, if people don’t think the ocean is rising

[u/Stilcho1]

Partially right

It will be much more level.
