Yes, climate change is real and we need to do more about it, but to say that one party's lack of action resulted in the bushfires is totally stupid and no-one can seriously believe it, though it makes good political propaganda.
Nobody is saying this. The 2,000 billion tonnes of carbon dioxide that's been added to atmosphere from human activities since the industrial revolution is what made the conditions this summer especially volatile. Obviously, Australia has only contributed a small % to this number, but every country must do something to combat climate change. The Liberal Party is doing nothing, and that's why they're facing backlash and that's why they're unfit to be in power.
