There has been an influx of articles in the Australian media lately undermining the scientific consensus on anthropogenic climate change. It begun with Peter Sheehan’s column in The Sydney Morning Herald on the 13 April (‘Beware the climate of conformity’). In it Sheehan reviews a book recently released by Australian geologist, Ian Plimer titled ‘Heaven and Earth’ questioning the scientific methods of climate scientists and concluding that dangerous warming is not occurring.
This generated a flurry of comments and inquiry, notably in The Australian, which published an article tracking Sheehan’s change of heart from 2006 to present. The first extract is taken from a column Sheehan wrote in September 2006; the second from his latest column.

DO yourself a favour. Go to see An Inconvenient Truth.
The story-line is as simple as it is stark: the Earth is in an intricately balanced equilibrium of temperature, ocean currents and weather patterns, and this equilibrium is being distorted. Massive disruption is going to occur without major corrective measures.

To reduce modern climate change to one variable, CO2, or a small proportion of one variable – human-induced CO2 – is not science. To try to predict the future based on just one variable (CO2) in extraordinarily complex natural systems is folly. Yet when astronomers have the temerity to show that climate is driven by solar activities rather than CO2 emissions, they are dismissed as dinosaurs undertaking the methods of old-fashioned science.
What this indicates, other than Sheehan’s impressionability, is the complexity of the debate and the fallibility of journalists in reporting scientific findings. Obviously the media has a role to play in voicing dissident opinions, but for the most part they have obscured rather than clarified the various positions on global warming.In attempting to honour journalistic objectivity by presenting ‘both sides’ of the story, the media has often given equal and unwarranted weight to the sceptic camp.
Not long after Sheehan’s column was published, The Australian reported on data indicating that parts of the Antarctic ice are growing (‘Revealed: Antarctic ice growing, not shrinking’) generating further scepticism in the editorial pages:
DELIGHTED doomsayers who applauded the announcement last week that an ice sheet on the west Antarctic cost was collapsing should leave the champagne on ice. Because, as Greg Roberts reports in The Weekend Australian, it appears everything is icier in most of Antarctica.
At the same time Miranda Devine was arguing in a similar vein under the headline: ‘Planet doomsayers need a cold shower’:
It seems that when it comes to convincing the Government to take drastic, jobs-killing, economy-crushing and ultimately futile unilateral action on climate change, the ends justify the means. “How we get there matters much less than the fact that [emissions] are very low by 2050,” CSIRO’s Dr Michael Raupach, told the inquiry.
The purpose here is not to take sides, but rather to highlight the confusing and often contradictory message emerging from these headlines. What is the public supposed to make of Devine’s article balanced against Garnaut’s call for urgent climate action? I would argue that there is a need for a more critical press in climate change issues; more investigative features to balance out the disproportionate number of opinion pieces in this highly technical and nuanced area. Without this I fear that the public will become -are already becoming- increasingly confused and often cynical about the entire climate change debate.
