What does our planet look like with 1 kilometre of sea-level rise or drop?

If all the ice on Earth were to melt, it could lead to a global sea level rise of approximately 70 meters (230 feet), according to estimates from the Intergovernmental Panel on Climate Change (IPCC).

Under no climate change scenario will there be an increase in the level of the world's oceans by more than 100 meters. However, it's intriguing to examine a hypothetical world map displaying a 1-kilometer increase in global sea level. 

The first two maps show what our planet looks like if sea levels were to rise by 1000 meters, how much of the planet's surface would still be above water.

Even if all the ice on our planet melted, the sea level would only increase by 70 - 100 meters. The maps above are just a bit of fiction.

The world maps with 1000 meters sea-level drop more realistic.

Suppose our planet's magnetic field faded, the atmosphere to be blown out into space. When atmospheric pressure drops low enough, water will start to evaporate taken by the solar wind.
