Australia is enduring a bushfire crisis that has left three people dead, razed more than 150 homes, and prompted warnings of "catastrophic" danger.
Bushfires are a regular feature in the Australian calendar, but the blazes in New South Wales and Queensland have not previously occurred on such a scale and so early in the fire season, officials say.
This has led many Australians to ask how closely the fires can be linked to climate change.
The science around climate change is complex – it's not the cause of bushfires but scientists have long warned that a hotter, drier climate would contribute to Australia's fires becoming more frequent and more intense.
But the nation's political leaders are facing a backlash for batting away questions on the subject.
What have Australia's leaders said (or not said)?
On Sunday, Prime Minister Scott Morrison refused to answer a question about climate change, saying: "My only thoughts today are with those who have lost their lives and their families."
When asked the same question, New South Wales Premier Gladys Berejiklian told reporters: "Honestly, not today."
Some Australians agreed, but others were furious the question was being ignored.
Mr Morrison later tweeted to offer "thoughts and prayers" to those affected, but critics compared that to rhetoric used by US lawmakers who have opposed gun reforms after mass shootings.
Deputy Prime Minister Michael McCormack stoked the most anger, when on Monday he dismissed climate change as the concerns of "raving inner-city lefties" who were ignoring the needs of rural Australians.
"We've had fires in Australia since time began," he said.
What is Australia's climate change commitment?
The nation's target under the Paris Agreement – the global deal to tackle rising global temperatures – is a 26-28% reduction in emissions by 2030. Some have criticised that as inadequate for a G20 country.
Last year, the UN reported that Australia – the world's largest coal exporter – was not on track to meet its commitment.
Mr Morrison told the UN last year that Australia was doing its bit to address climate change, and "balancing our global responsibilities with sensible and practical policies to secure our environmental and our economic future".
So are these bushfires due to climate change?
"We find it very difficult in general to attribute climate change impacts to a specific event, particularly while the event is running," said Dr Richard Thornton, chief executive of the Bushfires & Natural Hazards Co-operative Research Centre.
"But what we do know is that the average temperature in Australia now is running about 1C above the long-term average." He added fire seasons were starting earlier and "the cumulative fire danger" in many areas was growing.
Prof Glenda Wardle, an ecologist from the University of Sydney, agreed: "It's not every weather event that is the direct result of climate change. But when you see trends… it becomes undeniably linked to global climate change."
She said there was a "collective shift" in the timing and intensity of weather events.
Australian National University climate scientist Dr Imran Ahmed called it a direct link: "Because what climate change does is exacerbate the conditions in which the bushfires happen."
Will Australia's bushfires get worse?
"We will start to see the extreme end of the fire behaviour scale occur more frequently because of the increase of temperatures", said Dr Thornton.
"Everything we normally see as variability between a good fire season and a bad season is sitting on top of that extra 1C – and that means that the severe events will occur more frequently."
