YOU have to feel a touch of sympathy for the global warming scientists, journalists and other hangers-on aboard the Russian ship stuck in impenetrable ice in Antarctica, the mission they so confidently embarked on to establish solid evidence of melting ice caps resulting from climate change embarrassingly abandoned because the ice is, in fact, so impossibly thick.
The aim of the Australasian Antarctic Expedition, led by Chris Turney of the University of NSW, was to prove the East Antarctic ice sheet is melting. Its website spoke alarmingly of “an increasing body of evidence” showing “melting and collapse from ocean warming”. Instead, rescue ships and a helicopter, all belching substantial carbon emissions, have had to be mobilised to pluck those aboard the icebreaker MV Akademik Schokalskiy from their plight, stuck in what appears to be, ironically, record amounts of ice for this time of year.
In that lies a hard lesson for those who persistently exaggerate the impact of global warming. We believe in man-made climate change and are no less concerned than others about it. But the cause of sensible policy is ill-served by exaggeration; there is a need for recognition of the science, which shows there are variations in how climate is changing and what the impact is, or will be.
Professor Turney’s expedition was supposed to repeat scientific investigations made by Douglas Mawson a century ago and to compare then and now. Not unreasonably, it has been pointed out Mawson’s ship was never icebound. Sea ice has been steadily increasing, despite the Intergovernmental Panel on Climate Change’s gloomy forecasts. Had the expedition found the slightest evidence to confirm its expectation of melting ice caps and thin ice, a major new scare about the plight of the planet would have followed. As they are transferred to sanctuary aboard the icebreaker Aurora Australis, Professor Turney and his fellow evacuees must accept the embarrassing failure of their mission shows how uncertain the science of climate change really is. They cannot reasonably do otherwise.
