In 2019 and 2020, bushfires raged across Australia, burning over 16 million hectares of bushland and affecting more than 140 million native mammals. It was estimated that 61, 353 koalas were affected by the fires, pushing them even more towards extinction.

And this is only just one example of the destruction caused by wildfires.

Wildfires, also called wildland fires, are uncontrolled fires that burn in natural areas, such as grasslands, forests, and brushlands. Often, wildfires are caused by natural phenomenons or human activity.
Based on information given by the government, in Canada, almost half of wildfires each year, on average, are caused by humans. Canada's neighbour, the U.S, has a significantly higher percentage, with 85%. Moreover, human-induced wildfires cause more damage than those induced by nature. Something as innocent as a gathering (such as a gender reveal party) can spark a fire.

With nature-induced wildfires, the most common ignition source, is lightning, specifically hot lightning, which produces extreme heat.
Global warming, according to researchers, creates storms and increases the probability that they will produce lightning. There are roughly 25 million lightning strikes per year now, however it is predicted that this will increase by around 12% per degree of rise in global average air temperature.
Additionally, global warming has been exacerbating heatwaves and drought conditions. In the EU, last year (2022), it was said that fires had burned over three times more land as compared to expectations. The majority of the west of Europe saw a record-breaking heatwave that increased the risk of wildfires. Low amount of rainfall, wind, and high temperatures, together, are the perfect recipe for a wildfire.
Apart from the fact that global warming causes wildfires, wildfires also impact the climate. Wildfires release large amounts of carbon monoxide, small particulate matter, and carbon dioxide into Earth's atmosphere.

It is difficult to control nature's wildfires, however as humans, we can control our own actions. Slowing global warming, along with climate change, is a crucial step towards the prevention of wildfires. Environmental laws and policies, such as forest protection laws, can put a stop to deforestation in areas. Change is happening; many countries have already signed a pledge, promising to end deforestation by 2030, with the COP26 climate summit.
However, we still have more to do.
