King tides now regularly breach seawalls meant to protect Torres Strait Island communities, and it happened again last week.
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.
Australia’s coastline has moved before thanks to changes in sea level.

People have been forced to move in the past thanks to changes in sea levels that affected Australia's coastline.
How does Peter Singer’s figure of 750 million fit within the range of estimates on ‘climate change refugees’?
Ethicist Peter Singer told Q&A that climate change-related sea level rises are "estimated to cause something like 750 million refugees just moving away from that flooding". Is that accurate?

Wild seas have left beaches eroded and houses close to collapse.
The site of the hillfort of Vugala, northern Viti Levu island (Fiji). This was one of many hillforts in the area – home to a few hundred people according to reports from the 1840s – that were probably established around AD 1400 in response to conflict resulting from a food crisis that had come about as a result of an enduring fall in sea level.
Rising seas are one of the major concerns of Pacific Island nations, and looking at past sea-level change can help understand the future.

The way ice sheets respond to global warming may be more predictable than previously thought
In the aftermath of 2012’s deadly Hurricane Sandy, New York launched a US$20 billion plan to defend the city against future storms as well as rising sea levels.
Managing the impacts of rising seas for some communities is being made more difficult by the actions of governments, homeowners – and even some well-intentioned climate adaptation experts.
How much staying power? A calving front of the Antarctic ice sheet.
If we burned all fossil fuels, the loss of ice in Antarctica would raise sea levels 160 to 200 feet, but even our current trajectory could lead to dramatic sea level rise.

Human activity is driving sea levels higher. Australia’s seas are likely to rise by around 70 centimetres by 2100 if nothing is done to combat climate change. But 2100 can seem a long way off. At the moment…

A third of the permanent snow and ice of New Zealand’s Southern Alps has now disappeared, according to our new research based on National Institute of Water and Atmospheric Research aerial surveys. Since…

The tiny Pacific nation of the Marshall Islands could avoid being swamped entirely, although it will still suffer profoundly from sea-level rise.

It is widely predicted that low-lying coral reef islands will drown as a result of sea-level rise, leaving their populations as environmental refugees. But new evidence now suggests that these small islands…

Australia’s coral reefs and mountain-top ecosystems are set to suffer from climate change, according to the Intergovernmental Panel on Climate Change’s latest summary of the research. The threats to these…

As the science on the coastal impacts of climate change gets stronger, the protections for Australia’s coastal communities are getting weaker. If that continues, everyone will pay. Along the eastern seaboard…
