What's been dubbed the worst start to the bushfire season on record has refocused attention on climate change and the possible link to extreme weather events.

Firefighters are still battling dozens of blazes in Queensland, while authorities in New South Wales are on high alert for new outbreaks fanned by gusty winds and possible dry lightning strikes.

Natural Disaster Minister David Littleproud has played down any causal link between climate change and the bushfires, which have arrived just days after the end of winter.

But the Greens are blaming the fires on global warming, and they want Parliament to declare a national "climate emergency".
