Why does global warming cause the sea levels to rise, if water takes up more space as ice anyway?
Two factors. One, ice on land is melting, and that water runs downhill into the ocean. Two, and more important, while ice takes up more space than an equivalent amount of water, warmer water takes up more space (expands) than cooler water.
The Short Answer
Two factors. One, ice on land is melting, and that water runs downhill into the ocean. Two, and more important, while ice takes up more space than an equivalent amount of water, warmer water takes up more space (expands) than cooler water. The contribution of ice in the ocean 'shrinking' as it becomes water, is far less than what would be needed to offset the expansion of the liquid ocean itself as it warms.
