Conservationists should take heart that Australia is finally waking up to the biodiversity crisis in Australia’s north. It is an urgent problem: right now, a diverse assortment of our small mammals – bandicoots…
Researchers and firefighters have long speculated that fire tornadoes might exist. Now we know they do.

We’ve all seen footage of out-of-control bushfires sweeping the Australian landscape, burning out hectares of native forest in their wake. But you might not have heard of a fire tornado, let alone seen…
The United Nations Environment Programme (UNEP) is co-ordinating a new venture to tackle short-lived global warming agents such as black carbon. Should we be paying more attention to black carbon? Yes…
Humanity’s control of fire has led to a vastly changed atmosphere.

The evidence for a rapid shift in state of the terrestrial atmosphere-ocean system over the last two centuries (see figure 1) requires a deep time perspective, beyond events of the day. Tracing the original…
Scientists are increasingly expected to engage with the media to communicate their findings. My research leads me to believe Hobart is at risk from a severe bushfire disaster – but what are my responsibilities…
We know Aboriginal fires affected Australian vegetation, but now we have evidence they altered the monsoon too.

For thousands of years, Aboriginal Australians burned forests to promote grasslands for hunting and other purposes. Recent research suggests that these burning practices also affected the timing and intensity…

Aboriginal people worked hard to make plants and animals abundant, convenient and predictable. By distributing plants and associating them in mosaics, then using these to lure and locate animals, Aborigines…
The “reasonable person” would agree that disaster risk is best avoided. Under a changing climate, how exposed people are to risk and how socially and physically vulnerable they are affects how often disasters…
We all want to know how bad the next fire season will be, but working it out isn’t easy.

Bushfires are part of the Australian landscape and the psyche of its human inhabitants. This is particularly true as months of hot, dry weather approach. Recent warnings have predicted a dire summer ahead…
It’s true: many species will go extinct due to the direct and indirect impacts of climate change. We will have to make some hard decisions about where to invest conservation dollars for the best effect…
Fire has played a key role in human evolution, and will continue to do so.

We have been fascinated and repelled by fire for millennia. It’s the defining feature of humanity and it has powered all cultures. But our relationship with this fundamental element, whether wild or contained…
Cosy, sure, unless your house is on fire.

Last summer, the Victorian government allowed cattle to graze in the Alpine National Park. They claimed it was part of a scientific trial to assess grazing as a tool to reduce fire risk. Now it seems there…
