Liberal backbencher Danna Vale has defended her position as one of the dissenters.
She says she is not convinced there is a connection between human activity and global warming and the report went beyond the committee's terms of reference.
"There's great contention amongst the science community about if indeed there is contribution from human beings or if indeed the degree to which there is," she said.
"So I'm not a scientist but I have real concerns about coming up with the recommendations of a report and then actually finding that we have not taken any evidence on that topic."
I suppose ignorance is bliss...
