Climate Change, The Environment, Resources And Conflict

RISING sea levels could lead to failed states across the Pacific and require extra naval deployments to deal with increases in illegal migration and fishing, a Defence Force analysis says.

"Environmental stress" has increased the risk of conflicts over resources and food and may demand greater involvement by the military in stabilisation, reconstruction and disaster relief, the analysis, prepared by Defence's strategic policy division, says.

It warns there is a risk of a serious global conflict over the Arctic as melting icecaps allow easier access to undersea oil and gas deposits.

In Australia's northern waters, "climate change is expected to change the location of South-East Asian fishing grounds, causing an increase in illegal fishing," says a summary of the analysis. "This may raise demand for ADF patrols in these regions."

The warnings emerged as a leading NASA scientist, James Hanson, used an open letter to the US president-elect, Barack Obama, to single out Australia's coal exports as a significant cause of climate change.

"Australia exports coal and sets atmospheric carbon dioxide goals so large as to guarantee destruction of much of the life on the planet," Dr Hanson said.

The Defence analysis, titled Climate Change, The Environment, Resources And Conflict, was completed in November 2007 for the head of strategy, Michael Pezzullo, a deputy secretary who has since been appointed to oversee the preparation of the Defence White Paper.

"Environmental changes will reinforce existing concerns regarding land availability, economic development and control over resources," it says.

"Rising sea levels will affect states and islands with low-lying coastlines around the world … Food sources are also vulnerable to environmental changes."

A summary, obtained by the Herald under freedom of information laws, says: "Environmental stress, caused by both climate change and a range of other factors, will act as a threat multiplier in fragile states around the world, increasing the chances of state failure. This is likely to increase demands for the ADF to be deployed on additional stabilisation, post-conflict reconstruction and disaster relief operations in the future."

Defence refused to release the full 12-page analysis, saying its publication could damage Australia's defence capability and international relations.

The paper says climate change may lead to increases in refugees from Pacific islands, but says few are likely to be able to reach Australia.

"From a defence planning perspective, we don't know how quickly these changes will occur, exactly what their impact will be, or how states and societies will react," it says. "Nevertheless, climate change may affect security by increasing stress on fragile states, state and societal competition for resources, environmental threats to ADF infrastructure and increasing the frequency and severity of extreme weather events.

"Climate change is unlikely to increase the risk of major conflict, although there is one exception. The Arctic is melting, potentially making the extraction of undersea energy deposits commercially viable. … Conflict is a remote possibility if these disputes are not resolved peacefully."

The Prime Minister, Kevin Rudd, described climate change as a "fundamental" challenge last month when he released his national security statement.

Dr Hanson, head of NASA's Goddard Institute for Space Studies, said Australia was making "honest efforts" to tackle climate change but failing.

Carbon trading schemes such as that proposed by the Federal Government would slow the rate of greenhouse emissions too slowly, Dr Hanson said.

"This approach is ineffectual and not commensurate with the climate threat," he said. "It could waste another decade, locking in disastrous consequences for our planet and humanity."

Australia is the world's largest exporter of black coal, shipping about 230 million tonnes a year to supply just over a quarter of world export demand, according to the Australian Coal Association.

It is the nation's biggest export earner, but when burned overseas Australian coal generates more than half a billion tonnes of greenhouse emissions each year, or more than all emissions generated within Australia.
