Climate Change

This clear and cogent book is an important wake-up call. It should not need saying that it is impossible for human populations and economies to grow without limit on a finite planet, but that delusion is widespread. This book is a reminder of the inconvenient truth that should be informing our leaders ...

Forty years ago next Christmas, a cyclone devastated Australia’s northernmost city, Darwin. It is a disaster still clear in the living memory of most Australians over fifty, but it also belongs to the past, the time before we had become aware of climate change. At the time, it was the kind of natural disaster to be expected in summer in the Top End, even if its festive timing appeared ominous in some mysterious way. There have been government reports, memoirs, books, and documentaries about Cyclone Tracy. Forty years appears long enough for an event to become history, but the cyclone has not yet become integrated into a significant national narrative.

When the world changes faster than species can adapt, many fall out,’ writes Elizabeth Kolbert towards the end of her study on the mounting wave of extinction we are living through – and causing. The list of species dispatched by humans, directly or indirectly, is growing every day, yet Kolbert isn’t merely ringing alarm bells or giving a dour post-mortem. As the book’s subtitle suggests, she is interested in the history of extinction itself, from the very concept (which isn’t nearly as old as you might think) to its most dramatic examples to date.

With resource shortages looming and climate change a topic of intense discussion, it is becoming increasingly important for people to find ways to reduce their day-to-day consumption and carbon footprint. Greg Foyster’s Changing Gears seeks to explore the question of how to do so through the author’s own interesting, and no doubt exhausting, cross-country journey toward a greener way of living. Setting out to cycle from Melbourne to Cairns via Tasmania, which makes more sense in context, Foyster and his partner used the journey to force themselves into the sparse life of bicycle travellers, while visiting and interviewing a number of prominent experts and practitioners of conservation, green living, and social dynamics.

As I write this article in my Adelaide Hills home, surrounded by native eucalypts and introduced fruit trees, large areas in New South Wales are dealing with the consequences of some of the worst bushfires in recorded history. Remarkably, given the unseasonally extreme weather, the rugged terrain, and the ferocity of the fires themselves, there have been few human casualties. Nevertheless, the cost will be enormous, not only in terms of the physical reconstruction required, but also of the effort required for individuals and families to rebuild lives from the ruins of their destroyed habitations. I live in a bushfire-prone area, in a house that could not be easily defended in the inferno of a firestorm. We have made our plans. We think we know what to do in the face of the fire emergency we hope will never eventuate. But how would we cope in such a situation? In practice, we have no idea.

Wikipedia lists fifty-three books that are currently available on the subject of climate change, and this new book will make fifty-four. Such books fall into one of two groups: they either support the orthodoxy or dissent from it. Tony Eggleton’s book is one that supports it. It is well written, clear in its argument, quite even-handed, and comprehensive. I enjoyed reading it, even though I have my criticisms. Why do I criticise? Because I am a dissenter.

When BHP Billiton announced last month that it would indefinitely shelve its proposed Olympic Dam expansion in South Australia, some said it signalled the symbolic end of the mining investment boom. South Australian Premier Jay Weatherill’s reaction was particularly revealing. With his government now staring into a $1 billion black hole, Weatherill declared that he and the community had lost trust in BHP, and that the decision was a ‘major disappointment’. Many of Weatherill’s critics have suggested that his response betrayed his party’s zeal for the mining project, to the detriment of other sectors, with the sole aim of bolstering the state’s beleaguered economy. Putting ‘trust’ and ‘mining companies’ in the same sentence may be nothing more than political aikido. After all, given the tumescent economic growth that has come from the commodities rush, Weatherill’s reaction is predictable. Yet one can’t help but feel that his trust is misplaced.

In my recent commentary on The Garnaut Review 2011, I said ‘Climate change is often framed as a number of battles; between science and opinion, between sustainable development and economic growth, between government control and individual freedom ...’ (ABR, November 2011). Little did I know that my next review would be of a book about the Climate Wars, written by an active warrior in those battles, and subtitled Dispatches from the Front Lines.
