Why are Atlantic and Gulf coast property owners building back bigger after hurricanes?

'Building back better' refers to making communities more disaster-proof and resilient after they take a hit. But instead, some US owners are building back bigger homes in vulnerable places.

Coral reefs provide flood protection worth $1.8 billion every year – it’s time to protect them

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.

Design for flooding: how cities can make room for water

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.

Protecting wetlands helps communities reduce damage from hurricanes and storms

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.

Building housing on flood plains another sign of growing inequality

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 and rising seas are predictable, and we’re not doing enough about it

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.

An X-factor in coastal flooding: Natural climate patterns create hot spots of rapid sea level rise

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.

As communities rebuild after hurricanes, study shows wetlands can significantly reduce property damage

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.

Is Hurricane Harvey a harbinger for Houston’s future?

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.
