IPCC chief calls for ‘sane voices’ in local climate debate
As The Australian claims sea level rise is not linked to global warming, the world’s most influential climate scientist has called on “sane and rational voices” to speak out and correct the record.
More than 250 scientists have gathered in Hobart today for a summit of the Intergovernmental Panel on Climate Change, the UN’s climate science body. The Oz marked the summit’s opening with a front-page “exclusive” story which claimed there was “no link” between sea level rises and global warming.
In a telephone interview, Crikey asked the long-term chair of the IPCC Dr Rajendra Pachauri, in Tasmania for the summit, about the story.
“What is particularly important is that sane and rational voices must respond to these questions and this scepticism, and I think that should get adequate currency,” said Pachauri, who in 2007 accepted the Nobel Peace Prize on behalf of the IPCC. “Then people can make up their minds on their own.”
He called on the media to take responsibility for the stories they run. “Unfortunately in several parts of the world, the media gives disproportionate coverage to those who take a contrarian view, even if they represent a very very small percentage of either the scientific consensus or public opinion. They get almost equal billing, and to my mind that seems a little unfair,” he said.
Pachauri said climate change was particularly serious for Australia: ”From the looks of it, Australia is very very vulnerable to the impacts of climate change, you have droughts, you have heat waves. Sea level rise could be a serious problem in some parts of the country. So Australia undoubtedly is very vulnerable, perhaps more so than several other places in the world.”
The Australian has long run a sceptical line on climate change, particularly in its opinion pages. Today’s story, written by environment editor Graham Lloyd, relied on a paper co-authored by Australian scientist Dr John Church. The paper apparently “said it could not link climate change and the rate of sea level rises in the 20th century”.
But Church, a sea level expert with the CSIRO, told a media conference today that was not an accurate description of the paper.
“So sea level clearly is linked to climate change, it is clearly linked to increases in greenhouse gases, and that’s actually in the paper which was quoted by The Australian. So the quote is, I’m sorry, inaccurate,” said Church, a co-ordinating lead author with the IPCC.
While The Australian claimed the paper had found no increase in the rate of sea level rise, Church said the paper showed the rate of sea level rise had increased between the 18th and 19th centuries, and research showed a further acceleration of the rate during the 20th century.
Despite the persistence of scepticism, Pachauri was upbeat about global acceptance of the science of human-induced climate change. He thought some prominent sceptics were changing their minds: “I hope that will be the case once they see all the compelling scientific evidence, in this country and in other parts of the world.”
The public tended to respond slowly to difficult realities, he says, so time was needed to change attitudes “Business-as-usual has a very strong force behind it, and therefore to move away from business-as-usual takes time, takes effort, and I imagine you’ll see signs of change in the near future,” he said.
The IPCC chief was confident the world was getting the message on climate change: “I think the extent of awareness is growing very rapidly … I feel quite optimistic about the way things are going”.
Pachauri praised Australia’s carbon price, saying the IPCC had found a price on carbon was one of the most effective ways of encouraging low-carbon technology. “I think what Australia has done has to be commended and I hope other parts of the world will also see something similar being done,” he said. He also called on governments to remove subsidies on fossil fuels because they acted as a deterrent to alternative sources of energy.
