If all the glaciers melt how much will the sea level rise?

There are a lot of glaciers in the world and they can be found on every continent, except Australia. The largest glaciers are called ice sheets and they cover vast areas of Greenland and Antarctica.

The Antarctic Ice Sheet is the largest of all and if that were to fully melt the sea level would rise by nearly 60 m! By comparison, melting the Greenland Ice Sheet would only raise the sea level by 7 m. The rest of the glaciers are all much smaller and if they all melted the sea level would only rise by 0.3 m.

If every single glacier were to melt, the ocean would rise by nearly 70 m. But, it would take a very long time to melt all that ice. At the moment melting glaciers and ice are causing the sea level to rise by about 2 mm every year.
