<\/a><\/p>\n Last\u00a0week I attended a climate change and strategic military geography seminar held at Russell Offices in Canberra on the impact of climate change on Defence. The seminar was convened by the Global Change and Strategic Military Geography VCDF Group, that\u2019s held similar events before<\/a>. The two speakers were Helen Cleugh, leader of the CSIRO\u2019s earth systems hub, \u00a0and Will Howard, assistant director at Office of the Chief Scientist. Howard addressed another carbon issue that\u2019s largely independent of global warming: the problem of acid oceans. The core messages from the two presentations were that changes to the climate are already underway, that these changes don\u2019t respect national boundaries, and that Defence isn\u2019t immune from the impacts of climate change. (The presentations delivered by Cleugh and Howard can\u00a0be accessed online, here<\/a>\u00a0and here<\/a>\u00a0(PDF).)<\/p>\n Water and food scarcity, flooding, increased natural disasters, atmospheric changes, ocean acidification and increased costs will impact on many aspects of Defence\u2019s business.<\/p>\n Climate change is having a multi-faceted effect on many states, and it\u2019s interacting with other political, social and economic problems.<\/p>\n Livelihood insecurity\u00a0is a likely result of climate change in our broad region. There\u2019ll be more extreme weather events and volatility in the prices and availability of food, because climate variability disrupts food production.<\/p>\n There\u2019ll be possible increased tension over trans-boundary water resources and sea-level rise will threaten the viability of low-lying areas, with the potential for displacement.<\/p>\n I\u2019ve previously examined some of these climate risks to our military<\/a> and law enforcement<\/a> communities. I\u2019ve also considered the broad environmental security challenges posed by ocean acidification<\/a>.<\/p>\n Some of the implications for Defence emerged from the recent VCDF Group sponsored seminar.<\/p>\n There’s threat multipliers posed by a changing climate. These risks alter the roles and missions that our military undertakes as a result of the physical alteration of the operating environment, as well as changes to the nature, frequency and distribution of conflict.<\/p>\n
