Land ice is very important to sea levels, because when it melts, all the water that was on land moves into the oceans. Sea ice melting will not raise sea levels, because it is already in the water.

Why is sea ice melt does not contribute directly to sea level?
Sea ice is already in the water, so melting it doesn't affect sea levels.
Why has the ice in antarctica been melting so fast and how is it affecting sea levels?
since your mum lived with the dinosaurs and th ice age
Why is antarctica important to aglobla warming?
Almost all of Antarctica is covered by ice, so it's greatly affected by a global rise in temperatures. When this ice melts and glaciers collapse, sea levels all over the world rise.
Could you solve the problem of rising sea levels by wiping out all sea life?
Rising sea levels are not the cause of sea life. In fact, some types of plankton absorb CO2 from the water, and in turn this means that global warming is slowed, and so the ice caps don't melt so quickly, and so sea levels don't rise so much...
What are the effects of icebergs melting?
Icebergs melting adds fresh water to the oceans. Icebergs are floating already, so when they melt they do not cause a rise in sea levels. Glaciers and land ice, like the Greenland ice-cap, and any ice on Antarctica, do cause a rise in sea levels when they melt.
Explain why sea levels would rise as a result of global warming?
Water expands when it warms. So sea levels rise.The Antarctic ice caps melt as a result of global warming. This puts more water into the oceans thus raising sea levels.
The earth is warming up - How will this affect the sea level?
Warm water expands, so there will be some sea level rise from this.Floating ice at the North Pole will melt, but will have little effect on sea levels, as the ice is already in the water. The ice is all fresh water, but frozen, and fresh water is less dense than salt water, so there will be a very slight rise.All ice caps on land, including glaciers, Greenland and Antarctica will raise sea levels, as the water moves from land into the sea.
Will the melting of icebergs flood your coast?
No. Icebergs are in the water already, so their melting does not raise sea levels.Glaciers and land ice when they melt do raise the sea levels.
What will happen if the arctic melts vs if the antarctic melts?
The Antarctic ice could not conceivably melt entirely within the next few thousand years, because it is so large. In fact, only the small Antarctic Peninsula, to the south of South America, seems to have been noticeably affected by recent global warming. The arctic sea ice is melting, but melting sea ice does not really affect sea levels. The worst that could happen here is the extinction of the polar bear, and perhaps changing weather conditions in some parts of the northern hemisphere. Since sea ice is reflective, it has a cooling effect, so the loss of sea ice can also contribute to global warming. As the ice shelves and glaciers of the arctic region melt, sea levels will rise, as they have already begun to do.
Why was more land exposed during the ice age than it is now?
A large proportion of Earth's surface water was in the form of ice and so sea levels dropped significantly.
Does the Sea level drop when water is stored in expanding ice sheets and continental glaciers?
Yes. Ice building up on land (glaciers, Greenland, Antarctica) means that there is much less in the oceans, so sea levels fall.
What will the glaciers do to the sea level rising?
As the glaciers and icecaps melt they will make the oceans rise and it's all because of global warming. Sea ice is in the water already so its melting will not affect sea levels.
