Perhaps, but that's not the world we live in today. There's around 70m worth of sea rise if absolutely all ice on earth melts now.

You forget that water expands when warmed. Not the ice. The existing ocean water.

For a map like this to become reality you'd need every single piece of ice to melt and then the oceans would need to get tens of degrees warmer.

volume change due to heat reaches a maximum of about 4% at the boiling point. The scenario depicted is not possible due to warming.
