Over the past six months, tourists and locals have been shocked to see Byron's famous Main Beach literally disappearing. Satellite imagery and local knowledge has revealed what's going on.
Rising sea levels are as likely to trap people as they are to force them to move.
The next ten years will be a critical period in which research agendas can be developed.
In Australia, coastal flooding is expected to be worse along the northern coast in Queensland, Western Australia and the Northern Territory.
A new study has reported the world will lose almost half of its valuable sandy beaches by 2100 as sea levels rise. But cutting our emissions could keep some intact.
Sandy beaches are densely populated and occupy more than one third of the global coastline.
If nothing is done now, seas could rise a metre by 2100, and four metres by 2300.
The IPCC report says extreme sea level events that used to hit once a century will occur once a year in many places by 2050. This situation is inevitable, even if emissions are dramatically curbed.
A biodegradable sea wall is cheaper than a concrete wall. In addition, it's easy for local people to replicate.
Dumping millions of cubic metres of sand on the beach stops people from dealing with the reality of coastal erosion.
Planning for the growing risks of flooding that threatens the UK's cities, towns and villages is underway, but progress is too slow.
Rising sea levels and tectonic activity have eroded the coastlines of the low-lying Carteret Islands in the South Pacific.
Thousands of hydropower dams are under construction around the world. New research shows that by cutting off sediment flow, these dams can have big ecological effects on far-off bays and deltas.
Rising sea levels won't be solved by trying to fix the coast in place. For a defence from coastal flooding, we need to step back.
How far will we go to protect high-risk beachfront property? New research suggests local councils are too willing to spend public money to protect private landowners from coastal climate change.
King tides and rising seas are an increasing and predictable threat, but adaptation plans to limit the damage to coastal property are still not managing the political obstacles.
Coral bleaching on the Great Barrier Reef could lead to increased vulnerability of Queensland coastal cities and towns, and not only through its impacts on the tourism industry.
In the wake of the collapse of Malta's spectacular arch, which UK coastal features are under threat from the unrelenting forces of wind and water?
Conflicts over coastal areas have largely been between development and preserving what makes these attractive places to live. Rising sea levels are now complicating our relationship with the coast.
The real risk is from sudden storms – but there are ways to limit the damage, if cities start planning now.
