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..
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.
I wonder how he'd feel about a 3% pay cut.
