A new report shows that coral reefs reduce damage from floods across the United States and its trust territories by more than $1.8 billion every year – and pinpoints that value state by state.
Carbon storage in Australian mangroves can help mitigate climate change.
One surprising potential benefit of sea-level rise is it helps coastal wetlands store more carbon.

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.
Flooding in Sydney last week was the latest example of Australian cities’ lack of resilience to a more extreme climate.
Australia's coastal settlements are highly exposed to the impacts of climate change. Climate-resilient urban landscapes that can cope with large amounts of water need to become the new normal.

Rising seas and groundwater depletion, both driven by climate change, are making soils saltier in many parts of the world. Farmers will need help adapting, especially in developing countries.
Venice is set to be regularly 70% underwater and proposed tidal floodgates won't deal with the fundamental problems.
Flooding due to climate change may make coastal homes less valuable.

Coastal real estate prices appear to be taking a hit, but mostly in neighborhoods with more climate change believers.
Protecting coastal wetlands, like this slough in Florida’s Everglades National Park, is a cost-effective way to reduce flooding and storm damage.
Coastal development is destroying marshes, mangroves and other wetlands that provide valuable protection from hurricanes and storms. Research shows these benefits can be worth millions of dollars.
Relocation from risky areas is the only safe response.
Beach erosion in Nags Head, North Carolina, photographed May 15, 2005.
Many US coastal towns are building defenses to protect against rising seas and storms. This can encourage people to stay in place when they should be moving inland.
People of color tend to suffer financially more than whites after natural disasters, such as Hurricane Katrina.
A new study shows that natural disasters enrich white victims while hurting people of color, worsening wealth inequality. And government aid contributes to the problem.

Cities around the world, including Toronto, are building housing on flood plains knowing the risks in the era of climate change. Here's why that will contribute to growing inequality in our cities.
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.

Climate change is raising global sea levels. Now research shows that 'hot spots' where seas rise another 4 to 5 inches in five years can occur along the Atlantic and Gulf coasts, further magnifying floods.
Coastal wetlands are an effective first line of defense and act by slowing down storm surges and reducing flooding.
New research by scholars, conservationists and the insurance industry shows that coastal wetlands provide hundreds of millions of dollars' worth of protection from flooding, boosting the case for protecting them.
As flooding took hold in the Houston area, volunteers who suffered through Hurricane Katrina made their way to Texas.

Ad hoc boat rescues have become critical parts of disaster response efforts, a trend first responders have officially embraced.
Houston’s Interstate Highway 45 was totally submerged in the deluge.
The unpredictability of hurricanes makes it hard to say for sure whether climate change is making them worse. But we do know that sea-level rise and increased evaporation will worsen the impacts.

Major hurricanes threaten millions of people and billions of dollars in property along the Atlantic coast. Here experts advise on preparing, understanding forecasts and recovering after a storm.
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.

Many Australians live on the coast, but how much do we know about the risks? While average sea levels are relatively easy to gauge, the risk of flooding also depends on weather, landscape, and climate.
