    Massive fires have now been burning in Australia for 6 weeks or so. However publicity has been very minimal generally due to their presence in the centre of Australia, an area of minimal population and economic activity. Generally they have been started by lightning, although some have begun along highways caused by tourists being careless with campfires etc.
    BUT these fires have now destroyed 150 000 square kilometres which is an area bigger than quite a few countries or states in US etc. Their economic impact is limited, but the environmental impact must be substantial.
    Flooding rains 12 months ago generated rapid vegetation growth in regions where there is usually very little vegetation, the arid centre of Australia. With the onset of spring and warming temperatures and gusty winds along with some dry thunderstorms, the fires have begun and grown in size quickly with very few people in the region available as firefighters.
    In 1974, after a period of flooding rains, fire followed and eventually destroyed around 25% of the total Australian land mass. With distinct similarities up to now in seasonal conditions to 1974, there is a very high probability that this year will be a repeat of 1974.
    Of course some will see this as global warming etc, but in reality it is only a standard cyclical event in the context of Australia, but still at least in the short term quite damaging to the environment and the CO2 footprint of the Australian environment

    It's part of the natural cycle of the bush. Not the ones started by idiots obviously, but the ones started by lightning certainly are. As long as they're not threatening human life, let them burn.

    Nah. The amount of carbon released when vegetation is burned is the same as the amount of carbon used and stored in the vegetation when it's growing. Since much of the vegetation is not usually present in that location anyway (unlike, say, old-growth forests) the net effect of this on atmospheric carbon will be quite minimal.
