Water is very heavy – and it can move. Until now, changes to water on land have actually offset much of the rising sea level from ice melt. How? Gravity

Cities can take action to stop subsidence – or else they need to adapt.
Dykelands and agricultural areas are seen in the Bay of Fundy, which faces significant threats from climate change. Retaining a focus on the public interest will be essential to preserving its long-term health.

With the recent scrapping of Nova Scotia’s Coastal Protection Act, the future of Canada’s iconic Bay of Fundy now rests in the hands of private interests, with potentially significant consequences.

A coastal scientist explains why marshes, mangroves and other wetlands can’t keep up with the effects of climate change, and how human infrastructure is making it harder for them to survive.
Some Aussie beaches are being reshaped and coastal dunes are marching inland. We used data from aerial photography, field surveys, laser mapping and drones to study incredible rates of change.
A motorist stops to survey the damage to a washed-out roadway near McKay Section, N.S. on July 23, 2023. A long procession of intense thunderstorms dumped record amounts of rain across a wide swath of Nova Scotia, causing flash flooding, road washouts and power outages.

Public concerns for real estate value, and a focus on the self, make flood risk maps unpopular. However, these concerns should not dissuade governments from providing resources we can all trust.

The climate migration deal has been dubbed as offering Tuvaluans a lifeline, but others say it is a neocolonial arrangement that does not tackle rising ocean levels.
Even a small rise in sea level can have big impacts on coastal properties, so we must do all we can to limit the changes while taking them into account in coastal land-use planning.
A heatwave in 2022 redefined scientific expectations of the Antarctic climate. Now the global community must prepare for what a warmer world may bring.
Did the enormous West Antarctic Ice Sheet collapse the last time global temperatures were 1.5°C above preindustrial levels? The answer lay in the DNA of an octopus.

A recently signed Australia-Tuvalu citizenship agreement offers people displaced by climate change a chance to ‘move with dignity’. But staying with dignity has to be an option too.

The world is on track to exceed 2°C warming within the next five years, with dire consequences for polar ice, mountain glaciers and permafrost – and human society.
Agricultural communities in parts of Madagascar face shifting precipitation patterns and increasingly severe cyclones.

As seas rise, it is clear that traditional coastal defence approaches are unable to keep pace. Nature-based solutions offer considerable potential to protect coasts, people and biodiversity.
