Forest fires and climate change in Australia
hace 6 year
Australia is suffering one of the worst wildfires in decades. This crisis, which has affected millions of animals and thousands of people, has been intensified by the effects of climate change.
Forest fires are the uncontrolled spread of fire in natural forests and wooded areas.[1]. These contribute to the deterioration of natural resources, having a great negative impact worldwide, due to soil degradation, loss of biodiversity, emission of pollutant gases, greenhouse gas emissions, loss of human lives and economic losses.[2]. They can originate from natural causes, such as climatic conditions; or from human causes, such as burning of agricultural areas.[3].
In Australia, almost 50% of bushfires are generated by lightning strikes and mainly occur in periods when the weather is hot and dry.[4]. Although the presence of wildfires cannot be attributed to climate change, some of the consequences of climate change may have intensified their spread and the speed of their propagation.[5].
Long periods of drought
In periods of drought, the vegetation cover becomes flammable more easily.[6]. During the period July 2018 to June 2019 precipitation in Australia decreased by 24% from the annual average, recording the driest year since 1969. This caused major droughts, particularly in eastern Australia[7] area where most of the fires are located.
High temperatures
Vegetation burns faster at higher temperatures[8]. As indicated by the Australian Bureau of Meteorology, in the period from July 2018 to June 2019 the daytime temperature was 1.7°C higher than average, making it the second warmest year on record[9].
Drought conditions coupled with temperatures of approximately 40°C and strong winds (which are an oxygen supplier) have exacerbated the usual wildfires in the country, creating a catastrophic scenario.[10].
What can you do to help?
- You can donate to the Australian Red Cross here that has volunteers in evacuation and recovery centers.
- You can donate to The Salvation Army Australia. here who are providing shelter and meals to evacuees.
- The Australian Society of St. Vincent de Paul here is raising money to help evacuated families cover costs and rebuild.
- You can help the animals by donating to WIRES here, an Australian animal rescue NGO.
