When a bushfire rages so high it creates its own thunderstorm, it becomes a 'firestorm' - and makes life much more difficult for firefighters. We still have a lot to learn about what triggers them.
Bushfires were the most common disaster in New South Wales over the past decade.

Researchers have found a disaster "hotspot" in northern New South Wales, where nearly half of the state's most disadvantaged communities are found.
When New South Wales burned in 2013, Tony Abbott was quick to point out that individual events can’t be attributed to climate change. But they can.

The science of attributing extreme weather events to human-induced climate change has evolved rapidly in recent years. But how we communicate it to the public has not kept pace with this advance.
Australia’s oceans are heating up.
The new State of the Climate report outlines Australia's rising temperatures and its regional rainfall declines - and the trends that are locked in for the coming few decades due to greenhouse emissions.
Huge swathes of Tasmania have burned this year.

A comprehensive analysis of Tasmania's natural disaster risks has identified bushfire as the biggest threat, alongside emerging issues such as disease epidemics and heatwaves.
The Grampians after a bushfire in 2014.
The Grampians, like much of Australia, has swung from Millennium Drought to Big Wet and back again, putting animal populations on a rollercoaster that could get worse as climate change bites.
Fire rages through the forest in a typical Australian bushfire.
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.
Victoria was one of several states to suffer bushfires as temperatures soared in late 2015.

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.
Eventually reduced rainfall hit much of Australia thanks to El Niño.
From floods to drought, fire to famine, the 2015-16 El Nino has had a global impact.
Victoria’s wildflowers: best enjoyed up close.
Victoria's volcanic plains offer fertile ground for grasslands teeming with wildflowers. But that same fertility has also made the plains a tempting target for grazers and growers, and developers too.
Alpine meadows are a pretty rare sight in Australia.
The alpine landscapes of Australia's southeast and Tasmania are home to hundreds of rare plants and animals. They're healthy for now, but need careful looking after.

Wildfire makes up about 4% of the greenhouse gases added to the atmosphere each year.
Bushfires and heatwaves are expected to increase and significantly impact on Australian cities and urban communities.
How well does the 'smart' city respond to the devastating scale and impact of urban heat threats such as bushfires and heatwaves?
Throw another one on. Researchers tested plant flammability using a blow torch and barbecue.
You might think having trees around your home is the worst idea during a bushfire, but some plants can actually help repel fire.
Leatherwood flowers give Tasmanian honey its unique taste.
Tasmania's bushfires have hurt not only the state's forests, but also the honey industry that depends on access to the region's unique trees.

European invasion completely disrupted the way aboriginal Australians managed fire. Learning from Australia's first people could help us fight fires in the future.
The numbat, Australia’s equivalent of a meerkat, is one of the unique mammal species confined to the south west.

South west Australia is home to an astonishing number of plants and some of the country's weirdest wildlife. Now we need to protect it.
Indigenous Australians continue to manage fire in a way that reduces the risk to property and people.

Every year homes are lost in bushfires. But what if we build our houses to withstand fire?
Extreme fire events are pushing Australian wildlife towards extinction.
Recent bushfires have not just destroyed human lives and property, but pushed some species further down the path to extinction.
Fires are increasing: time to prepare.
