IPCC chief calls for 'sane voices' in local climate debate

The world's most influential climate scientist Rajendra Pachauri speaks to Crikey on the need for sanity and fair reporting in media coverage of climate change -- and explains why Australia should care.

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.

The IPCC issues major reports on climate change every five or six years; the last was in 2007, and this next report (which is the fifth) is due for release in September this year. Writing the report is a laborious process involving hundreds of scientists, multiple drafts and tens of thousands of comments from experts on each draft. The final report then has to be OK-ed by every member state of the UN’s climate body. A draft of the fifth report was leaked by a climate sceptic late last year.

Thomas Stocker, co-chair of that part of the IPCC which is meeting in Hobart (it’s one of a number of working groups on the fifth report), says 255 scientists from 39 countries are at the Hobart summit considering more than 30,000 comments received on the previous draft of the report. “We want to get this right,” Stocker told a media conference today.

The 2007 IPCC report concluded that “warming of the climate system is unequivocal” and “most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG concentrations” (GHG refers to greenhouse gas). The IPCC defines “very likely” as over 90% certainty.

Church says the fifth report has made significant scientific progress on the effects of climate change on sea level rise; this report would be more advanced than the previous one.

The IPCC experts speaking at the opening of the summit would not be drawn on what else the fifth report might contain, or on how precisely the scientists would be able to project the impacts of climate change. The summit runs until Saturday.

    I’m not sure anyone has a vested interest in climate change, except maybe the jellyfish (they’re doing well) and Shell (they’re trying, and failing, to drill in the Arctic).
    As for temperature increase, well take a look at
    http://thinkprogress.org/climate/2013/01/10/1421601/video-charts-planet-is-still-warming/
    Graham Lloyd of the Australian really needs to be spanked with a paddle for this latest effort. He’s not just a naught boy, he’s been deliberately devious.
    As for academic qualifications, Dr Pauchari has a publication track record that Christopher Monckton can only envy.

    Fascinating, since politicians don’t choose their pay. An independent committee does. It’s cute to harp on about a small error in the article blurb while batting eyelids and adopting a “just saying!” demeanor, but you ignore the rebuttal to your own accusations of his alleged vested interests.

    And the IPCC temperature projections are incredibly accurate, and far more accurate than any “skeptical” projection of “global cooling” which is always, always, on the horizon but which never occurs.

    The IPCC is still a highly respected, transparent institution and the number of errors in the last report numbered….one?

    Come on Keith, you are inept. Can you get anything right?

    Why don’t you tell me what’s causing the warming since 1880 using peer reviewed research and we can go from there. Try me.
