Tell me if I'm wrong. The land closest to the deepest oceans would see a higher and lower tide. Due to the moons gravity pulling on the less dense, water to solid earth area. If the ice melts on earth. Problem with the water heating up is this. With the melting of the ice caps gasses are released that would help replenish the ozone layer. In turn cooling the earth and waters. There fore returning to ice.
Icebergs are not frozen salt water. They are made up of fresh water, so when they melt they would not cause the sea level to rise. When ice forms in a salt water sea, fresh water freezes and the salt is left in the sea.
Icebergs are chucks of ice which have fallen in the ocean from land glaciers which are fresh water, so the experiment you would have to use is fill a glass of salt water to a certain level then measure, then add a chuck of fresh water ice and see if the water level increased and measure, then wait for the ice to melt then measure because salt water has a different density than fresh water, than publish those results.
Without watching the full video but seeing it up til 1min21... i would like to say its the buoyancy of water already displacing the ocean that allows for no change in sea level. I am no scientist or expert, just saying what i think. Will now read other comments to see if people said what i thought or if i am just wrong lol i invite your comments
What if you placed land in the aquarium or rocks before you put the water in. Mark the water level. Put half the ice on top of the rock. Then let it melt.
@@arielherbez4077 yeah it does. As another commenter replied: glaciers moving down and into the ocean as in Alaska is the exact same thing. Not that it is of any concern still; we move uphill 100ft and the newly submerged land creates that much more shallow surface area for new coral growth ❤
Why don’t sea levels rise every year when the arctic thaws? I mean around March specifically when it is spring in the Northern Hemisphere and only going in to Autumn in the Southern Hemisphere and has not begun to fully freeze yet. We can see massive ice loss from the arctic every year when it thaws. But we do not sea a corresponding sea level rise.
@@placidmink2537 thawing floating ice doesn't but most ice isn't floating its sitting on land and just looks like its floating because of how much ice is between the land and the ice
Hello, I’m a little confused here. Throughout the video you proved that the water level won’t rise when the ice melts however in the paper you mentioned at the end, it says that the sea level will rise will floating glaciers melt. Can you explain, thank you.
@@Mike-uo2gg The pure mass still isn't explained though. There just isn't ENOUGH glacier mass on the planet to explain an ocean rise by any appreciable figure - a figure that we'd need to really start worrying about. A contributing factor maybe, but I still feel there's something we're missing on the topic. I suppose the paper you linked even supports that idea. I still need to watch your next video on thermal expansion. As an aside - Perhaps the ocean is rising from all the junk we're throwing in it.. or the manmade islands other countries are making LOL.
@@Mike-uo2gg Yes, he did and SHOULD have offered the full conclusion rather than interjecting doubt and deferring the rest of the story until later. The rise in sea levels caused by melting floating ice is miniscule. In the research referred to, the publication 'The Melting of Floating Ice will Raise the Ocean Level' in Geophysical Journal International, shows that water from melting floating sea ice and ice shelves may add 2.6% more water to the ocean than the water displaced by the ice. Such melting would contribute approximately 1.57 or about 4 centimeters of rise.
I'm sorry it's still wrong. They have taught alot in schools that we later found out was very wrong. Like the history if lead at one point it was used as a sweetener for wine! And they thought it was OK and hamless.
One critical point that is disregarded here, I think, is the fact that the melting ice doesn't stay sweet water with a lower density (-> more volume then salty water) but it solutes part of the salt around it and thus becomes exactly the same density (-> exactly the same volume as salty water) again. Given the amount of salt is basically infinite in the ocean. They also disregard the fact that icebergs aren't just forming out of nowhere. When the water is melting, the salt is staying in the water creating denser water (less volume). It's a closed system contrary to a fresh water ice cube thrown into salty water in this amateur experiment.
Also consider, if ice sittning on landmass. And fall into the water.. Remember that whole earths water is an enourmous amount. So if u make an example with extra ice adding from outside in a glass of water compare to how big the sea are.. so then u should add a piece of ice wich is smaller then a dot on the keyboard.. and see the effect.. would be Great if u can make the exactly calculation how much extra ice goes into the water.. Im not a professor n my english is not good. But shouldnt we have any professor out there who can make the correct calculation with all angles added to the "subject???
Do the experiment yourself and do it right get a skinny glass fill it with ice fill it over the brim of the cup now add water to the brim any excess that is sticking out of the water will cause the cup to over fill hence sea level rise. 😉
Is it possible to make the sea level rise catastrophically if a rogue country like China or globalists created a satellite with ultrasonic technology to be aimed at a polar ice cap? I ask that because there's so much talk about a global order to confront climate change, but really it's about control. When I worked in Physical Therapy, sometimes we would do ultrasound underwater because water is a good conductor for ultrasound waves. Since our atmosphere is made up of O2 and some water molecules, would our atmosphere support ultrasound waves like water does in the analogy I used?
Salt or not the same amount of force is applied unto the water. Now ice melting of land would rise the sea levels because you are adding to the water to sea levels. If that’s the case why not show sea water with sea ice on a smaller scale because you would get the same results the sea level will stay the same.
@@pandorasactor7127 All of it is freshwater, that there discredits what they are saying. Same amount of pressure is force down on the water even if it was salt. Now if it melts of land and goes into the sea this will raise sea and ocean levels.Thank you.
Ice density is 91.7% of water's density (8.3% less), while just a 89% of the ice is under the water (11% floating). Given that, ice would rise sea level.
From what you readed water also get more dense in the summer I bet ... Yet you cant understand that when water warms it evapor and never raise the level of water but evapor in get dispense in the air wish the fall back in the land on so on .. ..
@@JustinWayneDawg I just stated a fact, one many get wrong because they do not realize the difference between an iceberg and a glacier. The extent to which the sea level will or will not rise is outside my expertise. My personal thought is that even if it did, and horrendously so, these arguments about the end of Man often discount mans ability to adapt and reshape our environment. They also do not tend to be very specific on how fast the sea might rise. Will it happen overnight, or in a few years? Hundreds? All of that data would matter in how we should react, if at all.
This whole video is redundant. The present Antarctic ice sheet accounts for 90 percent of Earth's total ice volume and 70 percent of it is fresh water. It houses enough water to raise global sea level by 200 feet.
Oh help me Rhonda. When ice melts it turns into a liquid and trapped air is released. It will SLIGHTLY contract when heated until it warms to 4C. Heating water warmer than 4 C means it will EXPAND. So as GW continues and the avg temp is well above 4C it warm, expand and this means sea levels RISE.
If you put a lump of ice into a pint glass, and fill it with water to the top, then press the lump of ice downwards until it is submerged, keeping your finger out of the water, the glass will overflow. No doubt i am missing something, but it seems to me that adding the ice that was above water, TO the water, does make the level rise. Does this not show, albeit at a smaller scale, that sea ice melting DOES make levels rise ??
What you are missing is the density change as the water moves through its phase changes. It is that density change that causes the ice to float slightly higher in the first place. The density change is reversed as the ice melts.
You are correct. But that is because you are forcing extra volume (the section above the pint) into the liquid. This is bound to displace extra liquid.
There’s air trapped in the ice and expands a bit but the weight is the same. The ice displace the exact weight of water as the ice weight’s which is also water. It’s a one for one exactly
Skip it. It’s there for those who want to know the detailed physics The takeaway is Icebergs melting do not contribute much to sea levels. But check out the next video
Won’t happen. Because of waters density, roughly 10% will sit above. The only reason there would be more ice above water level if it’s near the coast and it’s supported by land.
It's wrong..... the model and the experiment is flawed. Do this .... get a cup fill it with ice make sure the ice is stacked above the rim.. icebergs stick out of the water.... now fill it to the rim with water and watch it overflow as the ice melts down to the rim once the rim is reached it will stop over flowing . Thus the melting sea ice above sea level Will raise the sea levels .
No flaw at all. Do not allow your ignorance of the science to confuse people. As long as the stacked ice does not touch the bottom of the glass and is free-floating the level will not rise. However, if you do this with a cup stacked with ice that is "grounded" on the bottom of the glass, you are actually emulating the melting of Antarctic ice sheets and glaciers: the water rises.
@@Bracgypsy so how many glaciers are floating verses glaciers that are sitting on the ground? Well that's simple we have more ice over land than floating on the ocean so the sea level will rise. Even If you argue there is more on the water the fact we have any on land means the sea levels will rise by your own logic. So regardless of how it's happening the climate is warming we are also reaching a solar even in 2025 and the sun will be warming more. Check out the Carrington event. You would have a better argument if you said we the planet earth has not always had glaciers then you would have a valid point we will not drown however 90% of the populations Are going To be effected because they are on the coasts or next to rivers or water .... if less ice is prevalent we will see more of the water in the atmosphere so the rivers and lakes will rise too. We will see weather paterns change . Even rivers change course over time. The moisture over the pole will stop freezing some time. We are currently in a brief warming period in the middle of an ice age and we have record heat waves every year. That is impossible to dispute. The ocean has already warmed 2 degrees. And the land and the sea ice is melting. Watch PBS eons they give a great explanation of the solar cycles and the ice age and the brief warming period we are currently in meaning it will cool off drastically in the next 5 thousand years. Do we have that much time to wait? What happens then when the ice age is done will we have a runaway greenhouse effect that thickens our atmosphere and super heats the planet like we see on Venus? Only time will tell. I appreciate the comment. Keep learning and growing the more you know the better off and more prepared you will be for the future what ever happens. You might get a more responses if you don't pepper your comments with insults. I'm not ignorant or brainwashed I keep a open mind and look to history to see what might happen in the future regardless of politics. Its a grave concern and a pity that science has been politicized.
Not enough to to change anything, climate change is a fairy tale, nuclear war is the real threat. Stop being so hysterical, it comes off as really feminine. Climate change is a power grab for your freedom and money, do you believe everything the media/ politicians tell you.
