National Geographic has created some amazing maps showing the devastating effects that would result if all the world's ice melted.

 The earth currently contains five million cubic miles of frozen water which when melted could cause sea levels to rise by 216 feet.

 If this happened cities in Europe including London and Venice would be lost underwater, as would the whole of the Netherlands and most of Denmark.

These maps could be used in lots of ways in the classroom. I'm going to get students into groups and give them each a different continent map and an atlas and ask them to describe in detail the effects, including place names and calculating scales. Then students are going to describe what it would be like to live in an area effected by the sea level rise. Finally students are going to do some research to find out how far in the future these maps could be a reality.
