Aust faces potentially disastrous consequences of climate change, inquiry told
Military and climate experts, including a former chief of the defence force, have warned that Australia faces potential “disastrous consequences” from climate change, including “revolving” natural disasters and the forced migration of tens of millions of people across the region, overwhelming security forces and government.
Former Defence Force Chief Admiral Chris Barrie, now adjunct professor at the strategic and defence studies centre at the Australian National University, said in a submission to a Senate inquiry that Australia’s ability to mitigate and respond to the impacts of climate change had been corrupted by political timidity: “Australia’s climate change credentials have suffered from a serious lack of political leadership”.
The inquiry into the security ramifications of climate change also heard from some of the country’s leading climate scientists, who warned the security threats posed by climate change had been underestimated, and complained Australia had been “walking away” from exactly the type of research that would help the country prepare.
Other experts, however, counselled against “alarmist” predictions and said the focus of climate change response should be on those people most acutely affected by it, rather than the security concerns of developed countries most able to respond.
Mr Barrie said the security threat of climate change was comparable to that posed by nuclear war, and said the Australian continent would be most affected by changing climate.
“We will suffer great effects from these changes, such as new weather patterns; droughts, sea-level rises and storm surges, because we have substantial urban infrastructure built on the coastal fringe; ravages of more intense and more frequent heatwaves and tropical revolving storms.”
But he said the existential impacts of climate change were likely to be first, and most severely, felt across Australia’s region, the Asia-Pacific rim, the most populous region in the world.
