According to a new study, the oceans have absorbed more heat from climate change than previously thought. This could mean the Earth will warm even faster in the future than scientists have predicted.
Vast 'underwater meadows' would lock up lots of carbon.
Conservative skeptics of climate change may support projects focused on 'resilience' – for example, preparing a community for future major weather events.
Convincing people to see and appreciate the threats posed by climate change is one of the great challenges of our day. Insurers may be able to succeed where scientists and educators have failed.

Limiting global warming to 1.5C is a tough challenge but still within reach, according to a landmark report from the Intergovernmental Panel on Climate Change commissioned after the 2015 Paris summit.
The world needs to be carbon-neutral by mid-century to give ourselves a chance of holding global warming to 1.5C. With around 1% of the global carbon budget, Australia needs to rapidly do its share.
