The Political Will To Prevent Climate Change Is Lacking, Even As The Cost Climbs

Australians are being presented with another startling contrast between colossal risk and paltry action over climate change.
The latest scientific advice is that human activity has already caused an increase of 1 degree in world temperatures, with global warming estimated to reach 1.5 degrees by 2052 on current trends.
The cost is astronomical. The damage over the years to 2100 would reach $US54 trillion in today’s dollars if warming was kept to 1.5 degrees. The cost would climb to $US69 trillion if warming reached 2 degrees.

The obvious message from the report is to stop the 2 degree scenario. The scientists say this means halting the use of coal by 2050, accelerating the use of renewables and making mammoth investments to change the economy.
This cost is just as draw-dropping. The report says the investment would need to be $US2.4 trillion a year by 2034 across the global economy. There is no country-by-country analysis of what this means but Australia makes up about 1 per cent of global emissions, so it may have the same share of the expense.
Can Australia invest $US24 billion a year to avert dangerous climate change? That is more than the federal government spends on public hospitals.

The answer from the Greens is to shut down coal-fired power stations and stop coal exports, but only about 10 per cent of Australian voters supported this position at the last election by giving the Greens their primary vote.
The two major parties will not rush the closure of coal-fired power stations.
The answer from the government is to ask for more time to come up with a policy. The leadership turmoil in August left the Liberals and Nationals without a plan to reduce emissions.
Prime Minister Scott Morrison insisted on Monday that Australia would meet its emission targets "in a canter" but this is disputed by climate experts. It is a laughable message – nothing more than saying "trust us" – when the demise of the National Energy Guarantee proved again that the Coalition party room is incapable of reaching a consensus and then holding its nerve on energy and climate policy.
Labor has a 50 per cent target for renewable energy by 2030 but is yet to spell out how it would reduce emissions in government. One approach is to rebuild a policy from the wreckage of the NEG but this is easier said than done.
It is telling that Opposition Leader Bill Shorten signalled it was too risky to be too ambitious. "We are not saying that there won't be fossil fuel as part of our energy mix going forward," he said on Monday.
Political leaders are making a pragmatic assessment of the will of the Australian people.
The dismal assessment from the scientists is that even a political success on energy would not save the Great Barrier Reef as we know it today. The trend towards 1.5 degrees means damaging 70 to 90 per cent of the world's coral reefs.
It is hard to see an agreement in Canberra, let alone the world, that is strong enough to stop that happening.
