Asked if he was endorsing Senator Steele-John's comments,Senator Di Natale made no direct reply and spoke instead about the general argument being made by all Greens senators.

Asked why he would not give a direct answer,Senator Di Natale said:"The point that every single one of our senators has made is a very straightforward one and one that I agree with absolutely."

In an over-heated political debate during the bushfire crisis,some on the Labor side of politics blame the Greens for not voting for the Carbon Pollution Reduction Scheme in December 2009.

The stated policy was to reduce emissions by at least 5 per cent by 2020 based on 2000 levels.

Asked a direct question about whether the Greens could have backed the emissions trading scheme in 2009,Senator Di Natale skirted the question to discuss later policies.

"What we did was introduce much better legislation,"he said,referring to the fixed carbon price passed by the Parliament in 2011 and repealed in 2014.

Senator Di Natale said the 2009 emissions trading scheme was a policy that would"lock in failure"by setting a carbon price"next to zero".

Senator Di Natale said he would put a motion to the Senate to call on Mr Morrison to meet"immediately"with fire chiefs who are seeking a meeting over the threat of climate change and bushfires.

Liberal MP Craig Kelly said the Greens were exploiting the bushfire crisis to recruit members.

"We see the worst where we see the Greens politicians exploiting this tragedy to pump up their cult by saying things that are completely untrue,against the science and try to recruit more members to the cult,"Mr Kelly told Sky News.

Clive Hamilton,the professor of public ethics at Charles Sturt University,said it was wrong to argue"it's not the right time"to discuss climate change while the fires blazed.

"The gun lobby has used the same argument to shut down debate after mass shootings,"he said.

"Now is the right time to talk about the causes of climate change because the infernos and the drought drive home the message that scientists have been trying to communicate for years,that human-induced climate change will have catastrophic impacts unless we act."
