Hurt by sea: how storm surges and sea-level rise make coastal life risky | The Conversation

The journal Climatic Change has published a special edition of review papers discussing major natural hazards in Australia. This article by The Conversation, which was written in November 2016, is one of a series looking at those threats.

Australia is a huge continent, but a coastal nation. About 80% of Australians live within 50km of the coast, and a sea-level rise of 1.1 metres (a high-end scenario for 2100) would put about A$63 billion (in 2008 dollars) worth of residential buildings at risk.

Anyone who lives along Sydney’s northern beaches, especially in Collaroy, saw at first hand the damage the ocean can wreak on coastal properties when the coastline was hit by a severe east coast low during a king tide in June.
