Global warming and water levels

Contrary to all the other elements, water has a tendency to increase in volume when it transforms into a solid (ice).
When ice transforms into water, the volume decreases.
Anyone can test this out. Take a bottle, fill it to the brim with water, close it and freeze it. Once ice starts forming the bottle will burst open.
Another experiment that you can do is, take a glass of water, put some ice in it and mark the water level. Once the ice melts, check the water level and you'll discover that it's lower.

The claim that global warming is going to increase water levels is nonsense. The opposite is true. Global warming, if it's happening, will decrease water levels.

As far as I know is very true that ice has higher volume than liquid water however ice is mostly stationary in the poles. If this ice melts then the water will disperse all over around and make its way into the oceans and we are talking about massive amounts of water from ice bodies that cover areas of thousands of square kilometers, I think this is the point of melting ice caps.
Since ice has a lower density than water, a part of it will float and be seen on the surface.
Naturally people think, if the ice melts, it will add to the water level of the ocean. In reality it's not the case. If it melts, the water level stays the same.
Please perform the ice in a glass of water experiment.

No need to worry about ice that is on land.
If earth warms up, the water warms up and melts the ice that is in the water. The one that is on land will be unaffected. Especially at the poles since the air is always going to be below freezing due to the coriolis effect.

This is a representation of average temperature vs altitude. At the poles it's always freezing and always will be, no matter the temperature of the rest of the planet.

I certainly agree regarding Antarctica. The ice on Greenland is already melting however, which can lead to a significant rise on its own.

The only ice that is melting (and growing, recently https://yewtu.be/watch?v=YrDX07oYxI8) is the one in the water (the coast) because of changes in the water circulation patterns. Greenland is part of the north pole and the ice on the soil will never melt because the air will always be below freeing.

Iceland, contrary to what the name suggests, has almost no ice because it's outside the arctic circle.

The sun rays that hit the ice are mostly reflected back into space but, before reaching space, a part of it will be absorbed by the air, increasing air temperatures.
If the ice that is in the water melts, the surface will darken and most of the light will be absorbed by the water. This will lead to even faster warming up of the water and faster melting of the ice.
However, since most of the rays are absorbed by the water, the air above it will not absorb as much which will result in lower air temperatures.
