Phragmites, an invasive species, line this marsh at Sachuest Point in Middletown, Rhode island.
Phragmites australis, an invasive reed, has taken over wetlands across the US. But it also stabilizes shorelines and harbors many fish and birds. Is it time to compromise with this alien?

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.
A new climate model combines data on ice loss from both polar regions for the first time.
Climate scientist predict that the combined effect of ice loss in Greenland and Antarctica will be more extreme weather, with impacts on agriculture, infrastructure and human life itself.
Marshes at Blackwater National Wildlife Refuge on Maryland’s Eastern Shore.
Marshes, swamps and other kinds of wetlands provide valuable services, such as effective natural flood control. But they are being destroyed for development in many parts of the world.

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.

The Maldives may end up with perfect conditions for reef island building, but no new coral to build islands with.
Venice is set to be regularly 70% underwater and proposed tidal floodgates won't deal with the fundamental problems.

For many world heritage sites, flood risks are increasing. But what about places that don't have the funds for protection?
Bombarding people with scientific information has little effect. Something else is needed to jolt us out of our current climate trajectory.

Government agencies spend millions of dollars yearly to buy and demolish homes sited in floodplains. But the program is slow, cumbersome and doesn't always help those who need it most.
One African city trying to manage rising sea levels is Cape Town.
Without action about 50 African countries and surrounding islands will be affected by rising sea levels.
The process of laying internet cables on the sea floor is particularly sensitive at the coastlines.
Comparing the locations of key internet data centers and cable routes with maps of expected sea-level rise suggests it's time to shore up internet connections in the face of a changing climate.
Malcolm Turnbull promised to ‘step up’ Australian engagement with the Pacific last year. Will it continue now that he’s gone?
A key question heading into the Pacific Islands Forum is whether Australia can negotiate a new regional security agreement that heeds Pacific leaders' concerns.

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.

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.
The northeast edge of the Venable Ice Shelf, near Antarctica’s Allison Peninsula.
Last summer one of Antarctica's floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
Australian forces will need to be prepared for natural disaster relief missions.

Australia faces many security issues driven by climate change, including more international migration and an increase in defence personnel being sent on disaster relief missions, a Senate inquiry has found.
Scientists on Arctic sea ice in the Chukchi Sea, surrounded by melt ponds, July 4, 2010.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
The view from Indonesia’s Rote Island towards Australia.
There is plenty of debate over what route was taken by the first people to reach Australia. New research reveals a likely route through a now submerged chain of islands.

Long-term climate modelling may appear to focus on the impossibly far future. But the full impact of some climate processes won't be apparent for centuries.
