Climate change:counting the costs

The costs of tackling – and not tackling – climate change became clearer over the weekend, as prospects for a firm outcome, at next month’s Copenhagen conference receded.

A new report estimated that some 250,000 coastal properties, around Australia, could be at risk of flooding as sea levels rise, as a result of global warming.

It said Sydney airport is among the properties at risk.

Developments, on that scale, imply social disruption.

But property damage would just the start of all that.

Earlier studies have shown that many low lying Pacific islands could also be flooded, as Antarctic sea ice melts.

That could well involve the relocation of entire Pacific populations, involving people movements on a scale Australia has not yet seen.

Speaking at an APEC Leaders’ meeting in Singapore yesterday, the Prime Minister, Kevin Rudd, admitted officials, who  have been trying to get a firm outcome, from next month’s climate change talks in Copenhagen, had found themselves “running into all sorts of difficulties.”

“…and therefore it is time for leaders, politically, to step in,” he added.

The reality, though. is that there is now, effectively, no chance of reaching a binding agreement, on steps to tackle climate change, at the Copenhagen meeting.

That became clear when Asian leaders, at the APEC meeting, stepped back from their previous position, which had included a 50 per cent emissions reduction target.

Sources said this had happened at China’s insistence.

Mr Rudd insisted, though, that he will still be looking for “a robust outcome” from the Copenhagen meeting

The retreat by Asian nations, though, is certain to encourage climate change sceptics, when the government’s emissions trading scheme come before Federal parliament again  this week.

The Coalition appeared to be on the verge of a major breakthrough yesterday, in the private talks it has been holding with the government on its proposed legislation.

Reliable reports said the government is prepared to exempt Australia’s farmers, altogether, from its legislation, if the Coalition will pass it through the Senate.
