It is frequently argued that Australia’s CO2 emissions are tiny, and that there is no point in the Australian federal government acting. This is especially the case if the US, under President Trump pretends there is no problem, as their emissions are huge.
Unfortunately the Australian Government is already acting.
By not attempting to ameliorate climate change it is showing that it does not care about climate change, and that it will not object to other bigger polluters continuing to pollute. So it helps make CO2 production normal and produces more climate change.
By encouraging coal mining in Australia our governments (of all persuasions) clearly demonstrate that they care more for the profit of some companies, than they care about the land, people’s health or maintaining a climate balance. By taking this choice, they ally with the commercial and political forces which produce climate change. Saying that stopping mining might cost us money and jobs is irrelevant – virtue can be difficult, and there appear to be more jobs in renewables anyway.
By encouraging Australia to continue to have one of the highest CO2 emissions per head in the world, they are implying that a prosperous life style depends upon destroying climate stability and that destroying that stability should be encouraged.
They are also encouraging short term visions over long term visions, and short term profit over long term expense, which is probably not good for anyone in general.
By being half hearted or indifferent to climate change they provide an exemplar and excuse for other’s behaviour (‘If wealthy countries in the West can’t be bothered, then why should we?’). If they acted to cut emissions and support renewables (or support thorium research, if you prefer) then they would be providing an exemplar of behaviour which also might influence other governments and corporate behaviour.
So let us be clear the government is acting. Just not the way we might think is sensible.
As for things like ocean fertilization or carbon capture and storage, they are likely to help prolong our use of fossil fuels. They are also likely to have weird and unintended effects. They may not even work other than in theory, or only work for a short time. We may need to deploy such methods, but the proper research will take longer than we might have to prevent climate turmoil (transformation is unlikely to be linear or smooth) and we have to move to 100% renewables or non-fossil fuels eventually. Why not start now, and help everyone achieve this, as well as make money for our scientists and companies out of the IP?
