As the Great Barrier Reef suffers a second wave of mass bleaching, there is a way to get involved.
The merchant navy – some 20,000 ships – carries the vast majority of trade goods around the world. Unfortunately, they also spew toxic pollutants that harm people and the environment.
The federal government seems keen to usher in a new boom in onshore gas production. But gas firms will need to tread carefully, as past experience in Queensland's fracking heartland shows.
The record floods of 1954 and 1974 still stand as Lismore's high-water marks. But Tropical Cyclone Debbie delivered her deluge far more abruptly than the rains that triggered those historic floods.
The Great Barrier Reef is in crisis, as a second wave of coral bleaching hits. But the system of bodies and laws that protect it are getting more complicated – and less productive.
New research has uncovered a whole new way to combat the devastating crown-of-thorns starfish, by decoding the pheromones that they use to communicate.
From luxuries like champagne to the very livelihoods of fishing communities in the developing world – the climate-driven shifts in species will affect us all.
Sydney, Melbourne and many other areas can expect to pay more for veg from next month, after widespread crop losses in Bowen, a major source of winter vegetables such as tomatoes, beans and capsicum.
A new training course designed to help volunteers feel like a key part of the team could help to reduce attrition rates among Australia's estimated 240,000 volunteer emergency service workers.
Estimates released by the Australian Bureau of Statistics suggest that the number of direct full-time equivalent jobs in renewable energy activities has continued to fall from its 2011-12 peak.
