Australia fires cause and effect. Lightning however is the principal cause for ignitions and justifies for fifty per cent of Australian bushfires ignitions. Apocalyptic footage of monstrous fires heroic firefighters injured animals and tourists in. When wind speeds are below this threshold fires with heavy fuel loads burn slowly.
There is a threshold wind speed of around 12 to 15kmh which makes a significant difference in the behaviour of bushfires in the open. This tactic happened on such an extreme level in Australia that humans were able to drive hairy rhinoceroses massive birds giant kangaroos wombats and other massive marsupials to extinction. Some have said that the bushfires in New South Wales and Queensland Australia are a regular natural occurrence.
50000 years ago Australian Aboriginals used fire stick farming as a way to hunt large animals. Australia relies on resource sharing arrangements between countries and states and territories within Australia. The arsonists were responsible for about 50 of the bushfires.
And one analysis suggests disruptions caused by the fire. While the fires rage on it is projected that more damage will be done. Fires are usually caused by lightning strikes or accidentally by a spark - but some fires are also started deliberately.
It is becoming more dangerous to fight fires in Australia. A longer fire season. Medical bills from the fires and smoke haze could also run into the hundreds of millions.
Equipped with torches humans burned forests to drive out trap and kill things to eat. Accidental causes such as unattended campfires contribute to a minor portion. Thunderstorms generated by the Australian bushfires are very likely to have pumped as much smoke into the stratosphere as a volcanic eruption.
