in California, people have built homes in the hills. Clearly, UNMANAGED land surrounds their homes. Is this different in Australia? I doubt it. And they will burn. In Australia, no trees, no homes, is more typical, because no water

why do you bother to comment when you can't be bothered to familiarize yourself with what is actually happening down there? Up thread I've posted an article that speaks to the manner in which the Aboriginals and the European immigrants managed bush fires and they continued to do that up until the last decade when they were not allowed to do that by law. The Aussies realized they live in a land that has always had fires and hence they needed to manage the fuel situation...this is not something new, common knowledge and common practice in Australia until it was legislated against.
As to California, well there is nothing keeping them from knocking down trees around their homes to build fire breaks (something that the National Forestry Service recommends), or building their roofs and homes from fire-resistant materials. They don't do this either because they think it is better to be in amongst the trees or they are just too lazy. The Smoky the Bear policy which saw all small fires put out immediately also resulted in an enormous amount of forest floor fuel from dead trees. Historically that fuel was eliminated over time by natural fires that were small mainly because they died out from lack of fuel before they could reach tree crowns. Now with all that extra fuel you have a situation where climax fires are quite common, as long as there is fuel they will keep burning and that is exacerbated by the Santa Anna winds.
Both California and Australia suffer from an excess fuel problem. The Aussies know how to deal with it but are kept from doing so by government regulations. The Californians seem to ignore the problem (that they could mitigate) with a view that the government will look out for them.
Of course climate change is part of the problem in Australia.....the climate is getting hotter, mate. Thats just reality.
A statement like this is meaningless without some data to demonstrate that 1. fires in Australia are a result of a hotter climate, 2. fires in Australia are increasing in areas where temperatures are increasing 3. droughts are increasing resulting in fires. None of that can be demonstrated and in fact the exact opposite is the case. Fires have always happened in Australia, the largest ones at a time when climate change was not an issue and the absolute largest one at a time when precipitation was above normal and temperatures were below normal. The map I posted earlier shows where the heating trend has occurred in Australia and for the large part it is nowhere near where the fires are. Instead, large fire areas occur in places like Cairns which have seen almost negligible warming over the past 50 years according to BoM data. Droughts are not increasing in Australia in fact in many of the areas which have horrendous fires currently the pan evaporation which is measured regularly by the BoM has been increasing (the opposite of what would happen in drought conditions).
The classic example of a disconnect between climate change and Australia bushfire occurs when you look at the 1974 - 1975 summer. The worst bushfire in 30 years occurred burning over 117 MMha of land (about 15% of Australia land area). At that time all of Australia and the areas where the fires were in particular had been subject to above normal precipitation and below normal temperatures. For Australia as a whole the rainfall anomaly was 215 (well above the average) and the temperature anomaly was -1.72 (below the average). The exact opposite situation to what you would need to claim fires were a result of climate change.
But your 'data" consists of a map that talks about future projections based on models. If you were, in fact, a "scientist" you would be interested in the actual data.
