Australia Fires Cause And Effect

The catastrophic bushfire season we are currently experiencing in Australia is a clear example of the impacts of climate change playing out before our eyes.

Australia fires cause and effect. This means it is harder to prepare for worsening conditions. Accidents deliberate acts of arson burning of debris and fireworks are as well other substantial causes of wildfires. There is a threshold wind speed of around 12 to 15kmh which makes a significant difference in the behaviour of bushfires in the open.

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 arsonists were responsible for about 50 of the bushfires. This infographic explains how climate change influences bushfires in four ways.

Deliberately lighting fires or arsonists are increasing and form 25 of the ignitions of Australia. 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. Australia relies on resource sharing arrangements between countries and states and territories within Australia.

And one analysis suggests disruptions caused by the fire. 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.

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

Fires can cause ember storms which can lead to additional fires when embers. A longer fire season. Gleick says that the bushfires can have a ripple effect both on the local landscape and on the global climate.
