A report questioning climate change and calling global warming a "natural phenomenon" yesterday led to accusations Australia's Prime Minister John Howard was a climate skeptic, possibly denting his re-election hopes.
A group of four government lawmakers - two of them former ministers - said climate change had been observed on other planets and moons including "Mars, Jupiter, Triton, Pluto, Neptune and others".
But this statement triggered a scornful response from the opposition.
"Prime minister, what planet are these government MPs on?" Labor Party environment spokesman and former rock star Peter Garrett asked Howard in Parliament.
The four released a report debating the science of carbon capture and underground storage, or geosequestration, opening a climate rift in the government.
"Climate change is a natural phenomenon that has always been with us and always will be," they said in a document challenging the findings of a cross-party parliamentary report looking at carbon capture options for Australia.
"It is the natural property of planets with fluid envelopes to have variability in climate. Thus, at any given time, we may expect about half the planets to be warming. This has nothing to do with human activities," the four said.
Howard, 11 years in power, is fighting accusations he has been slow to respond to climate change, which is shaping up as a key issue for national elections widely tipped for November.
He has announced projects to combat climate change as polls show eight in 10 Australians are concerned about global warming. International reports say the drought-stricken country will be hard hit by rising temperatures and greater extremes in weather.
The four lawmakers - a majority of the six government MPs on Parliament's Science Committee - took issue with the parliamentary report recommendation calling for government funding and tenders backing major carbon storage projects.
The Australian Greens said their leader - former scientist turned MP Dennis Jensen - was a climate "dinosaur", while Howard remained a self-confessed global warming skeptic.
"His language has changed because he recognizes the opinion polls show that Australians are really worried about climate change, are angry that he's done nothing," Greens Senator Christine Milne told radio, referring to Howard.
"While these are the musings of Liberal backbenchers, what they demonstrate is how climate skepticism goes to the heart of the Liberal Party and indeed the coalition," she said.
Howard told parliament he did not agree with the four, but his opponents envisaged "a planet inhabited by people who hate the Australian coal industry". Australia is the world's largest coal exporter.
In a major report, the UN climate panel said in February that there was at least a 90 percent probability human activities were the main cause of global warming in the past 50 years.
Delegates who approved the UN report at a meeting in Paris agreed a "best estimate" that temperatures will rise by 3 C by 2100 over pre-industrial levels, the biggest change in a century for thousands of years.
