Australia holds the potential to sit amongst the world's renewable energy superpowers, but "unprecedented" bushfires across NSW reveal just how lacking the government's climate change policy is.

Days after thousands of scientists from across the globe declared humanity was facing a climate emergency, scores of bushfires tore through NSW, so far killing at least three people.

It appeared Prime Minister Scott Morrison wanted to steer clear of another climate debate, dodging the topic on Saturday as fears grew more people may have perished.

But a local mayor, climate change policy expert, firefighter and resident whose family home was destroyed in the early-season fires have all told The New Daily they want climate change at the centre of the conversations about the deadly emergency.

Glen Innes Severn Council's  mayor, Carol Sparks, who lost her home, said: "There is no doubt about it, we are suffering from the effects of climate change and global warming.

"The trees are dying and they are so dry and volatile," Mr Sparks said.

"We’ve got no water in our dams, no water in our rivers, no water in our creeks."

By Saturday evening, three people had been confirmed dead. One victim identified was 69-year-old grandmother Vivian Chaplain.

Ms Chaplain, who was trying to save her home and animals, was rushed to hospital after being found unconscious with burns to her half her body, NSW Premier Gladys Berejiklian revealed later that day.

She was one of two people who perished in the Kangawalla fire which raged east of Glen Innes in NSW. A third victim died in a burnt-out home, north of Taree.

Mr Morrison seemingly dodged questions on Saturday about whether climate change was to blame for the out-of-control fires in that state.

When questioned directly about climate change, he answered: “My only thoughts of the day are with those who have lost their lives and their families, firefighters who are fighting the fires, the response effort that has to be delivered and how the Commonwealth has to respond and support those efforts".

Labelling the unfolding bushfire emergency as a "terrifying beginning" to the fire season, Ms Duncan said she was "deeply saddened that many more people have lost their homes, and that more people have died".

She blamed the Morrison government's inaction on climate change for exacerbating the threat of more fires.

"I’m disturbed that our government has ignored – and continues to ignore – the repeated calls for genuine climate action from our community, and from the scientists who have warned us that climate change will make bushfires and other natural disasters happen more frequently and become more intense," Ms Duncan said.

"We can’t continue to pretend it’s unrelated," she said.

Local RFS captain Paul Johnston who was battling the blaze near Nymboida River said he faced an "unprecedented" bushfire.

“I don’t think that I can articulate exactly what I felt but this is something that’s never happened to this degree – certainly here,” he told the ABC.

Above-normal temperatures and below-average rainfall will continue to dominate the coming months, NSW RFS Commissioner Shane Fitzsimmons said.

“We have got the worst of our fire season still ahead of us. We’re not even in summer yet,” he told reporters on Saturday.

Climate change has made fires more likely and "when they start they're more likely to get out of control", said Greg Mullins, Climate Councillor and former NSW Fire and Rescue Commissioner.

"Year on year our fire seasons are starting earlier so the official fire danger season in NSW which in legislation was based on 100 years of weather observations is October 1," Mr Mullins said.

"In the last two years, we had fires in the first or second of August."

"So if this evidence isn't enough to convince people, I don't know what is.

"But people like me who have been doing this for decades are just shaking our heads and we have a sense of doom."
