A group of 13 Australian scientists has offered two climate-sceptic federal Liberal MPs a briefing ahead of the release of Australia's post-2020 emissions targets.
West Australian backbenchers Dennis Jensen and Chris Back will accept the offer, but want a parliamentary inquiry held before emission reductions are decided.
Dr Jensen told ABC radio on Tuesday he believes there are a number of people within the party who agree there shouldn't be significant cuts.
The pair backed a motion at the federal Liberal council meeting last month, seeking a parliamentary inquiry.
But it was referred to the party's policy committee instead of being debated in public.
"I think sometimes these uncomfortable issues are precisely the issues that need debate," Dr Jensen said.
The former physicist is sceptical about the Intergovernmental Panel on Climate Change's models, which he says have proved "quite lousy" in terms of predicting global average temperature trends.
But Professor Ove Hoegh-Guldberg from the University of Queensland's Global Change Institute, who co-signed the letter offering a briefing, denied that.
"It's just like the stock market," he told ABC radio from Paris, where international talks will be held in December.
"If you look at that it's going up and down but it'll have a trend - that trend is what we're watching."
