Ice sheets and sea level:
There is much water stored in land ice on the Earth. As this ice melts and runs into the oceans, sea-level will rise, though it will not rise by the same amount everywhere. Globally, sea-level rise due to ice melt on land alone is expected to reach 20-30 cm by 2100.
However, for tropical regions, this can become 40 cm of sea-level rise. As ice continues to melt in an increasingly warmer environment, sea-level could rise a couple of meters in the next few hundred years. If global warming continues unabated, this could become 7 meters or more over the next few thousand years.
