Sea rises threaten Australian homes: Govt report

Nearly a quarter of a million homes along Australia's coastline could be submerged by 2100 unless action is taken to stop sea levels rising, a government report said on Saturday.

Debate on climate change, and a government proposal to introduce a carbon trading scheme are the very focal points of political debate, with parliament due to reopen on Monday.

With prime minister Kevin Rudd's Labour Party far ahead in polls and the conservative opposition divided on the issue before next month's Copenhagen climate conference, ministers are seeking passage of the legislation to guard against an early election.

Minister for climate change Penny Wong presented the report, "Climate Change Risks to Australia's Coasts", saying 157,000 to 247,000 residential buildings would be at risk if no action were taken and sea levels rose by 1.1 metres (3 ft 7 in).

"The science tells us our climate is changing faster than first projected, and the impacts are likely to be more severe as sea-level rises, and extreme storms and floods become more frequent," Wong said.

She said the report underscored the need to reduce carbon pollution, "which is why we are determined to pass the Carbon Pollution Reduction Scheme. It also shows that Australia must plan to adapt to the climate change we can't avoid."

Wong also announced the creation of a seven-member council to examine the effect of rising sea levels on coastal regions.

Australia, the world's biggest coal exporter, produces about 1.5% of global emissions and is one of the world's highest per capita emitters of greenhouse gases.
