Australia Fires Cause And Effect

Fires can cause ember storms which can lead to additional fires when embers.

Australia fires cause and effect. Australian National University climate scientist Imran Ahmed told the BBC there was a direct link because what climate change does is exacerbate the conditions in which the bushfires happen. The impact of the devastating bushfires on Australias tourism industry is expected to cost the industry hundreds of millions of dollars while the images of smoke and fire carried worldwide are expected to be a deterrent to international visitors. Spotting can occur up to 30km downwind from the fire front.

50000 years ago Australian Aboriginals used fire stick farming as a way to hunt large animals. When wind speeds are below this threshold fires with heavy fuel loads burn slowly. A study of Queenslands historic 2018 bushfire season found the extreme temperatures that coincided with the fires were four times more likely because of human-caused climate change.

Large pyrocumulonimbus storms above the fires in Australia are acting like chimneys shooting smoke high into the air as if they were volcanic eruptions or nuclear explosions. Accidents deliberate acts of arson burning of debris and fireworks are as well other substantial causes of wildfires. While the fires rage on it is projected that more damage will be done.

It is becoming more dangerous to fight fires in Australia. The costs of fighting fires are increasing. Cause Impact and Restoration With evidence that climate change is causing Earths temperatures to rise we are seeing fires around the world increase and occur in areas that have not historically experienced them.

Lightning however is the principal cause for ignitions and justifies for fifty per cent of Australian bushfires ignitions. 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. Accidental causes such as unattended campfires contribute to a minor portion.

The fire season has lengthened so substantially that it has already reduced opportunities for fuel reduction burning. Gleick says that the bushfires can have a ripple effect both on the local landscape and on the global climate. There is a threshold wind speed of around 12 to 15kmh which makes a significant difference in the behaviour of bushfires in the open.
