From the Sydney Morning Herald: as part of an exhibition called “Australia from Space,” geographer Stephen Young has created six images of Australia that show how the continent would look if the world’s sea levels were to rise anywhere from 100 to 500 metres. (At right, 300 metres.) Worth noting that even under extreme global warming, the sea levels aren’t going to rise as much as that; Young did not create these images for didactic purposes.
