The only thing is that this diagram makes it seem like the sea levels rising is caused by ice melting, while in reality it is because as water heats up, it expands.
Ice that was on land will raise the sea level if it melts.
Sure, but the amount of ice on land is but a small spec compared to the water in the ocean.
If all the ice in the world melted, it wouldn't affect the ocean level that much. Compared to thermal expansion of the water.
Ice melting is a symptom, not a cause.
You're right about sea level rise over the last century, but the big sea level rise at the end of the last ice age was in fact mainly a result of ice melting — big parts of North America and Europe had ice thousands of feet thick on them.
Melting all the ice in the world today would add almost 200 feet to sea levels.
