DAWSON MP George Christensen has used taxpayer funds to pay for books that consider the threat of climate change to be a conspiracy or a hoax.
The MP's spending habits were revealed in the latest expenditure reports from the Department of Finance.
Mr Christensen was reimbursed for books including Tower of Babble: How The UN Has Fueled Global Chaos, Taxing Air Australia and The Greatest Hoax: How The Global Warming Conspiracy Threatens Your Future.
The Tower of Babble -- a nine-year-old "tell-all" on a climate change conspiracy created by the UN -- was good enough for Mr Christensen to purchase two copies.
The Greatest Hoax from US Senator Jim Inofe describes how the concept of climate change is "blatantly and categorically false", according to the book's description.
Senator Inofe has previously likened the US environmental regulator, the EPA, to the Nazi Gestapo.
He has previously said global warming was "the second-largest hoax ever played on the American people, after the separation of church and state".
Mr Christensen has long been outspoken on his position of climate change science, speaking at a US function for the Heartland Institute -- a conservative think-tank against global warming.
In July 2014, the ABC reported he said climate change warnings were "comedic", comparing them to Hollywood disaster films.
"It's hard to tell the difference between an alarmist claim about global effects and the basic premise of a disaster movie plot."
Revolt from the Heartland: The Struggle for an Authentic Conservatism, It Takes a Family: Conservatism and the Common Good and even issues of the home with Men on Strike: Why Men Are Boycotting Marriage, Fatherhood, and the American Dream - and Why It Matters.
The MP also bought The Political Speechwriter's Companion: A Guide for Writers and Speakers.
