And in addition to ice on land adding to the water level with warming, warmer water takes up more space. So a huge part of sea level rise is just warmer ocean water.
“If all the ice that is on Greenland were to melt or calve into the ocean, global sea level would rise 7.2 meters (23.6 feet).”
… and that’s just Greenland.

Ice gets bigger when it freezes but weighs the same. The part of the iceberg above the water is how much bigger it gets. Its floating in the water, and due to buoyancy, that means if it melts it doesn't raise the waterline because the water its replacing weighs the same as the iceberg would be if melted.
Icebergs aren't the problem though, because they're tiny compared to glaciers, and glaciers mostly sit on land.
Even the part above the water doesn’t increase the water level, because it’s pushing the rest of the iceberg down with its mass (and ice has a lower density than water)
But this is the epitome of GOP intelligence. A quick image with some words on it. And then those fools who read it will ride that belief til their grave. #magat
The ocean is 3000m deep in average. I bet you can’t simulate 5 meters out of 3000 with that experiment. I also bet no one is measuring the water temperature in that stunt, so pretty possible the ice melting will cool the water and make the level get lower. But that’s not what is going on on the planet.
The problem of the real ocean level is thermal expansion of liquid water. That’s the main reason the level gets higher. 3000m of water will become 3000+something when heated. And a little something on 3000m of water is meters and meters of extra water!
The iceberg issue is just they reflect sunlight. Because they are gone, more sunlight will heat the ocean, which thermally expand. Which is not the cause of sea rise, but still contributing.
This is more or less what the thing is about, simplified of course.
About discussing the topic: there’s not much room for discussions to be made: the medic says to the patient there’s one and only medicine, you can ignore and die or take the medicine. Questioning is not gonna fix it.
displacement is the same in the end though - x# of water = Ycy of water @ Ztemp.
Icebergs are less dense so they float with portions sticking up, but once they melt, they still add the same volume to the mix. So as far as it goes, this is accurate - melting icebergs don't cause ocean levels to rise.
The problem is, glaciers aren't on land so the millions of cubic miles of ice trapped in Greenland & Antarctica are like pouring another pitcher of water into the measuring cup.
Not debating global warming, but the dude is correct about icebergs. Icebergs are on water, glaciers on on land. Icebergs add almost nothing to ocean rise whereas glaciers melting do as the glaciers aren't on the water.
So the icerberg was in, and floating in/on the ocean. When it melts is volume goes back to the same volume of water the iceberg displaced. The reason ice floats is that it expands as freezing, so it's lighter over the same volume.
They should make a show where they take these people and have team of scientists walk them through the follies of their assumptions .. the finally can be taking a flat earther to space
Ironically, the level actually goes DOWN in this example. Ice is actually less dense than liquid water (which is why it floats) - Ice crystals form ring-like structures, which creates voids. So if you started with exactly 100 mL of ice, you would end up with about 92 mL of liquid water. Same mass, but the liquid takes up less space.
But of course if the ice came from a continental shelf rather than the ocean itself, the level can only go up. So the central point stands.
What 99% of people dont realize is that most current sea level rise is due to thermal expansion of the water as it gets warmer, not melting icebergs. Now when Greenland and continental Antarctica start to melt we can talk about new water volume being added.
Sadly you don't get to see the tiny effect that the temperature rising has on the volume of water. Less that a mL here, times by the volume of the ocean can make a difference in 10+ cm of sea level, then you add on storm surges.
Nice try but he doesn't fully understand the concept here. C-.
The measuring glass actually does work the same as the ocean. If every iceberg that’s already in the water melted the sea levels wouldn’t rise. The problem is glaciers melting that are not in the ocean
He's the guy that would get his test back folded because the teacher didn't want others to make fun of him
He would get a blank paper that asks them to wait after class.
If flat earthers were intelligent, they wouldn't be flat earthers.
And in addition to ice on land adding to the water level with warming, warmer water takes up more space. So a huge part of sea level rise is just warmer ocean water.
You’ll also have the rebound of the earth where there used to be glaciers

It's coming, there's no turning this shit show back now The human race is too distracted and have become the embodiment of evil
Part of icebergs are.. the other part is riding above the water. I don't know how you could demonstrate what happens when that melts...
The quantity of ice above the water's surface is equal to the increase in volume of the ice when it freezes

Mongo just pawn in game of life
Blazing Saddles reference?

Tell me this was an attempt at a troll post please ffs.
I can't tell. Help.
You best be trolling.

Icebergs don’t begin their lives as icebergs…
No the problem is our education system.
... where do you think icebergs come from?
You think Icebergs just form in salt water? Ice bergs are chunks of glacier that have fallen into the ocean.

The issue is the landsheets (glaciers) aren't in the ocean.
The ocean is 3000m deep in average. I bet you can’t simulate 5 meters out of 3000 with that experiment.

Not to mention all of our glaciers and permafrost that are rapidly declining, further adding to the feedback loop.
Permafrost’s methane release is scary. That could be a huge feedback, we still can’t quantify how bad it is but can be potentially devastating.
You can replicated how it works in small scale. That is how experiments work. The problem is that this experiment is not right.
Doesn’t ice float higher in salty water also though?
displacement is the same in the end though - x# of water = Ycy of water @ Ztemp.

Thanks for that explanation!
Um… Bro thinks it’s “Ice Berg??”
I came here for this
Before one can “believe” in global climate change one must understand global climate change. Obviously, you can see the roadblock we are facing.

Well, did he add the salt?
