The Australian Greens have failed to get Senate agreement that coal is the biggest contributor to climate change, despite putting denials alongside the world's wackiest conspiracy theories.
Party leader Richard Di Natale moved a motion on Monday noting the upper house accepts humans first landed on the moon on July 20, 1969, and the earth is round.
The motion also called for the upper house to accept that burning thermal coal is the single biggest contributor to climate change, a move designed to compare denial with conspiracy thinking.
One Nation senator Malcolm Roberts asked for the vote to be split so the climate change part of the motion was separate to the conspiracies.
While the moon landing and round earth parts passed on voices, the thermal coal section was defeated 31 to 29.
Independent senator Cory Bernardi called out the Greens for using the northern hemisphere moon landing date as they tried to be "clever" about climate change.
He said the landing happened on July 21, 1969 Australian time.
"We are in the southern hemisphere. You are senators in the Australian parliament. You are not part of the Donald Trump or Kennedy administration no matter how much you'd like to be," Senator Bernardi said.
Meanwhile, the minor party's lone MP Adam Bandt has introduced draft legislation to the lower house that would give workers the right to strike for climate action.
It comes ahead of global climate strikes this Friday.
"This is the beginning of an uprising that will only grow if government's fail to tell the truth about the climate crises and fail to take emergency action," he said.
"Students have asked workers to join them this Friday. Any boss who sacks anyone for not turning up to work this Friday is a bum."
Mr Bandt criticised the government's pollution reduction commitments, saying the world was on track to heat up by 3.5 to 4 degrees.
"(That) will lead to global warming that is a death sentence for billions of people on that planet."
Mr Bandt also hit out at Prime Minister Scott Morrison for "boycotting" UN climate talks in New York next week, which will instead be attended by Foreign Minister Marise Payne.
