Ok we know that global warming is a fact and it can cause the polar ice caps to melt. But my question is this, isn't the polar ice caps just a giant block of ice that sits on top of the ocean? So even if it melts its shouldn’t cause the sea level to rise a lot.
Why? Because if u take a glass of water and put a ice cube in it cause the water level to rise, however after the ice have melted the water level stays the same. So if the polar ice caps is just a giant ice block that set onto of the ocean doesn't that mean even if it melts it shouldn’t cause the sea level to rise?
Maybe somebody has mentioned this before but i can't find it anywhere.
So am i right???
