Tidal marshes can build up their soil to keep pace with sea-level rises – up to a point. It turns out the point when the marsh is drowned matches the average rise when global warming exceeds 1.5℃.

Property buybacks and managed retreat from high-risk areas were once seen as far-off options as the planet warms. Now this ‘last resort’ adaptation to climate change is an urgent priority worldwide.
For the first time since satellites started studying the continent, East Antarctica has lost an entire ice shelf.
New breakwater designs and more sustainable materials can cut the carbon cost of coastal defences by 40%.
Globally, about a billion people living in coastal cities are at risk of climate hazards. The impacts go well beyond the coast and could affect us all, with disruptions to supply chains and trade.
As the impacts and costs of climate change increase over time, New Zealand’s financial systems could become less stable and the government less able to support those affected.
Rich countries have promised to compensate poor ones for the impacts of climate change.
The triple whammy of the moon’s wobble, sea level rise and more intense storms will bring worse tidal floods into coastal communities in the 2030s. This includes in Australia.
Survey respondents who overestimated the amount and speed of sea-level rise were more likely to express greater concern. But concern is not always helpful in prompting action.
Around the world, fragile coastal ecosystems are under intense pressure, and understanding and managing their complex interactions requires an integrated and interdisciplinary approach.
When Antarctica’s land-based ice melts, the land bounces up slightly as the weight of the ice lifts. This affects sea levels across the world, but not enough to offset sea-level rise.
The next ten years will be a critical period in which research agendas can be developed.
More than 1 billion euros were donated after Paris’ cathedral was grievously damaged by fire in April. By comparison, just a few million euros were given after catastrophic flooding in Cité des Doges.
New research shows that warming by more than 2°C could be a tipping point for Antarctica’s ice sheets, resulting in widespread meltdown and changes to the world’s shorelines for centuries to come.
To address environmental degradation, including climate change, it is essential to take into account human rights and migration. Hybrid international law and regional thinking are both essential.
A researcher on sea level rise and climate change impacts reviews Kim Stanley Robinson’s new novel, ‘New York 2140,’ which envisions the city’s future in the face of extreme sea-level rise.
