Unless I missed something, there doesn't seem to be a thread devoted to the terrible bushfire catastrophe ravaging Australia, which I find a little surprising. Anyway, I will post my deepest sympathy here, and also add a question.
Bush fires have both natural (lightning) and pre-industrial human (aborigine) causes. Although there can be no question that climate change is contributing to the ferocity of the Australian fires, I wonder if human activity has also made them worse by preventing smaller and more frequent fires that otherwise would have naturally occurred. Is this a case of one big fire (yes, I know there is more than one) in place of many little ones?
