In how many years will most of the Torres Strait Islands be in water?
Thousands of years ago, when sea levels where much lower than today, the Torres Strait was a land bridge between Australia and Papua New Guinea. Rising sea levels turned it into a series of islands. As climate change continues to cause more sea level rise, these islands will get smaller. Parts of the islands are more than 100 m above sea level, so there is no risk of the entire island disappearing. But, as the sea level rises, high tides and storm surges become much bigger problems. A storm surge is the increase in sea level that happens during a cyclone or other large storm. Sea level rise is already making the impact of these extreme events much more severe, and this will continue to get worse as the sea level rises.
