Editor's note

Almost half of Australia’s coastal habitat has been damaged by extreme weather events linked to climate change. Mangroves, kelp and seagrass have all been affected and this has a knock-on effect as they’re vital for other marine life. But, as Russ Babcock and colleagues write, some of the areas will struggle to recover as these extreme weather events are set to get worse.

The trees in our cities are also in the front line of climate change, with new research finding some of the 30 most common species that make up more than half of Australia’s urban forest are unlikely to survive in some cities.

Twitter isn’t just for political hashtag warriors. Many still use the social network to just hang out

Axel Bruns, Queensland University of Technology; Brenda Moon, Queensland University of Technology
