Even as the dust storm over NSW subsides, the unseen fine particles outside, or even inside your house, can still present a health risk.
The California fires are just the most recent in a series of major wildfires. Together, they suggest we need to look at alternative ways of living with fire.
Grass trees are wonderfully odd. They fit no neat definition, and can live up to 600 years.
In the aftermath of fires or logging, conservation needs to focus on recovering the health of the remaining vegetation, not just the size of the forest or woodland.
In NSW and Victoria this week, communities were hit by bushfires. Long after such devastating fires pass, the risks to physical and mental health remain.
What decisions can we make today to reduce the future risk of hazards like floods and fire? Particularly in a time of climate change, modelling various plausible futures helps us plan for uncertainty.
Climate change should have a significant impact on fire activity across the globe.
Rebuilding small communities on the same site in the same way seldom works. It’s not about getting back to where you were, but rather grasping the opportunity to create a more resilient place.
We can manage the risks from bushfires far more effectively if we look at the ways different plant species control the the way the fires burn.
2015 was the world's hottest year on record. The US State of the Climate report has rounded up the litany of temperature and other records that were broken all over the globe.
From floods to drought, fire to famine, the 2015-16 El Nino has had a global impact.
Wildfire makes up about 4% of the greenhouse gases added to the atmosphere each year.
This summer has seen Tasmania suffer through drought, bushfires, floods and the worst marine heatwave on record. Is this what life under a climate-changed future will be like?
You might think having trees around your home is the worst idea during a bushfire, but some plants can actually help repel fire.
European invasion completely disrupted the way aboriginal Australians managed fire. Learning from Australia's first people could help us fight fires in the future.
Victoria is moving away from burnoff targets to a new strategy for managing bushfire risk.
