Low lying regions could be devastated by sea level rise this century.
If nothing is done now, seas could rise a metre by 2100, and four metres by 2300.
Aerial imagery revealing the extent of storm damage in Dee Why on Sydney’s Northern Beaches in 2016 following wild weather.
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.
Scientists working together with local people to create an eco-sea wall to protect against coastal erosion.
A biodegradable sea wall is cheaper than a concrete wall. In addition, it's easy for local people to replicate.
Bacton beach defences.
Dumping millions of cubic metres of sand on the beach stops people from dealing with the reality of coastal erosion.
Flooding in Wainfleet All Saints, Lincolnshire, which received two months rain in two days in June 2019.
Planning for the growing risks of flooding that threatens the UK's cities, towns and villages is underway, but progress is too slow.
High tide at Nukatoa Island, in the Takuu Atoll, Papua New Guinea.
Rising sea levels and tectonic activity have eroded the coastlines of the low-lying Carteret Islands in the South Pacific.
The San Pedro Mezquital River is the last free-flowing river in Mexico’s western Sierra Madre.
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 much should a council pay to protect private beachfront properties?
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 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.
Parts of the Great Barrier Reef’s outer reefs can form a natural barrier to coastal recession, thus protecting urban centres.
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?
The original conflict between development and preservation of natural assets is broadening as the risks of climate change become ever more obvious.
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.

Wild seas have left beaches eroded and houses close to collapse.
While some councils wish to take a long-term view of what can reasonably be done in the face of sea-level rises, private property owners just want their homes protected.
Many properties are at risk from rising sea levels, with owners and councils at odds over the costs of defending these. NSW law reform may lead to more forward-looking climate change adaptation.
Coastal communities around Australia are facing the rising threat of coastal erosion.
Coastal communities include 24 federal seats held by margins of 5% or less, and their local councils are pressing the Australian government to show more urgency about the impacts of climate change.
Hard at work, so you can have fun in the sun.
But sandy beaches aren't just tourist eye candy – they're a vital defence against coastal erosion.

Unless something is done to curb erosion, Ghana's coast could soon whither away.
Stack ‘em high: big, health reefs take the sting out of stormy seas.

Coral reefs: fragile, delicate, and in danger? Actually coral reefs can be the first line in defence against incoming storms, reducing the power of incoming waves by 97%, even during hurricane-force winds…
