    It may have happened before, but with more to lose it will be harder to recover. If this becomes the new normal it does not matter how the fires start, it is the end result that matters.

      Agstar, look deeper. Read up on the natural proliferation of eucalyptus trees that drop oily leaves and release and oily evaporate into the local low level atmosphere. The Blue Mountains are named from this phenomena.

      The name Blue Mountains, however, was preferred and is derived from the blue tinge the range takes on when viewed from a distance.The tinge is believed to be caused by Mie scattering which occurs when incoming light with shorter wavelengths is preferentially scattered by particles within the atmosphere imparting a blue-greyish colour to any distant objects, including mountains and clouds. Volatile terpenoids emitted in large quantities by the abundant eucalyptus trees in the Blue Mountains may cause Mie scattering and thus the blue haze for which the mountains were named.

        When looking at co2 levels on windy.com. The south hemisphere has low levels of co2. 40ppm. The North is a lot higher. If co2 was a problem the North should be way hotter or what ever they claim is supposed to happen.

          It seems the canary is alive and well in Australia.
          During this period of CAGW, Australia has enjoyed increasing rainfall, decreasing droughts, increasing crop yields, declining area burnt by wildfire, declining human suffering and death from natural causes.
          The only negatives have been an increase in environmental activists blocking any attempt to prevent future bushfires, and sky high unreliable electricity, both of which are easily mitigated with very few resources.

          Isn't tweety a canary?

            Fire effectsEdit
            Fireweed is a native wildflower that grows after forest fires.

            Despite today's sophisticated and expensive fire-spotting and fire-fighting techniques, forest fires in Canada still burn, on average, about 28,000 square kilometres of boreal and other forest area annually. That average annual burn area is equivalent to more than three times the current annual industrial timber harvest. It can be many more times that in intense fire years.[47] However, although logging also removes trees, fire is not the same as logging, since fire has been a part of coniferous forests for millennia.[25] Fire not only stimulates regeneration of many plant species, it recycles phosphorus and removes accumulated organic matter. Fire is increasingly used as a management tool to maintain forest health in some parts of North America (see fire ecology). Different parts of the boreal have different burn cycles. The drier western region, which receives lower average rainfall, had higher natural fire frequencies. Hence, more area is burned annually on average in the west than in central and eastern Canada.[48] When natural burn cycles are interrupted by fire suppression, natural renewal is obstructed and species composition is changed. In addition, fire suppression causes fuel loads to increase so that fires, when they do occur, become more intense. One can argue that fire suppression actually creates a positive feed back loop, where ever more expensive fire suppression generates the conditions for ever larger fires. The negative effects of fire suppression are still under study, and not fully measured, but they need to be considered when making decisions about the future health of boreal forests.
