Ice melting.

So a thought struck me the other day, and i wonder if its logical... In any case, if someone knows the answer to this id be glad if they could clarify it for my.

Lets start with an assumption.
1. The structure of water changes when turned into ice. During the transformation process the ice expands. (this can be tested at home by freezing water in a filled bottle, the bottle will crack and/or explode)
As far as i know this expansion is about 9%. But im not sure of those numbers since i haven't found more then 1 source for that. so this is also just an assumption at the moment.

Now here comes the problem, I and most likely many of you have heard on the news
and on/in movies and other kinds of media, also hearing from friends and family and so on, that the world will basicly drown if the ice melts in the poles.

Is that true though? Since the water expands and take up more space when turning into ice, then it would logically decrease in mass and take up less space if it melts. No considering that an iceberg only shows around 10% of its total mass and thus hides 90% of its mass under water. Shouldnt the waterlevels of the world actually lowered when the ice melts? Technically by 9% of the total mass of ice if the number is verified.

This is no troll post, but i figured that it would be interesting just throwing it out there.

Short version. Should'nt the sealevels decrease if the ice melts?

Ice floats on water, when the ice that floats melts and turns into water, the ocean levels will rise. Seems pretty simple to me.

yes, well. Thats what most people belive anyway, but only 9% floats above water and 91% "floats" under water, so the ocean levels shouldnt rise at all if you factor in the decrease of mass when the ice melts.

What kind of genius calculation is this?

According to your own numbers 10% of the iceberg is above water (this is probably terribly wrong) and the volume contracts by 9% when the ice melts.

So the surface still rises by 1% even if everything you said is accurate (it's not).

The melting ice that increases the sea level is the ice that is on land and not the floating ice. That why one of the main factors we look into for rising sea levels is the amount of ice melting greenland. floating ice doesnt raise sea levels beacuse the volume of the ice that is under watering keeping it bouyant is the same volume of water that will be produced when the ice melts as ice is less dense than water.

there's a lot of ice on land

antarctic and glacier ice aren't floating they are sitting on land, which they will run off of when they melt.

You do know there's a lot of ice on land right?

Greenland and Antarctica are above sea level.

perform an experiment, put ice and water on your sink. measure the levels. measure it again after it melts

If I understand you correctly, I think this would be the solution to your idea:


To summarize the situation with Antarctic ice trends:

Antarctic land ice is decreasing at an accelerating rate
Antarctic sea ice is increasingn

This theory seems easy enough to test in a cup of water, but as far as I know the density changes enough to counter the volume increase such that when it melts there will be 0 change to overall water level.

The problem is when ice that's not floating, but resting on continents (greenland and antarctia) melts and streams down into the sea. That's what will cause sea level rise in the event of the ice caps melting.

I think we need to remember that scientists also factor in the melting of glaciers as well.

Well, math isnt my strong point... at all... but i agree the numbers looks a bit wrong. As i said earlier in my post, i havent been able to verify the numbers yet, i only found a single source of it, so please take the numbers with a grain of salt until they have been verified.

Ice Sheets/Continental glaciers (like greenland) are the big issue. These glaciers will primarily lead to the rising sea level.

Water temperature effects ocean currents and climate. Ocean currents determine where water goes. Not to mention floating ice, glaciers, etc.

Hmm, yes it is the ice upon land that will be the problem then, thanks for pointing that out. Does anyone know how much water the land will absorb upon a gradual melting?

The water level increasing is due to the ice that is on land; primarily on Antarctica and Greenland.

Apart from ice on land: Water has its highest density at 4°C, so as soon as water becomes warmer than that, it expands again.

Thank you for those, i will look into them.
