How does burning less coal do "absolutely nothing about climate change"? If you state something like that you have to at least give a convincing argument.
fruityrudy is arguing in other comment replies that the Australian coal is "only 3%" of CO2 emissions so he probably thinks that's so close to zero it's basically zero and negligible..
I wonder how he'd feel about a 3% pay cut.
Climate change is not directly proportional to co2 in the atmosphere. To reverse it requires large reductions. China, India, US. Australia’s production and usage is a rounding error at the moment.
