Hundreds of fires have ignited since 2019, causing a local ecological crisis as billions of animals have died, but the problem has started to spread its influence across the planet.
Since the Australian wildfires started previous year, they have released 400 million tonnes of carbon according to climate scientists.
Those 400 million tonnes take the form of acrid smoke billowing from the country, which has now started to creep overseas.
But much of the smoke from the bushfires has lingered over the continent.
Professor Iain Colin Prentice, Chair of Biosphere and Climate Impacts and Director of the Leverhulme Centre for Wildfires, Environment and Society, Imperial College London, added: "Wildfires can't be prevented, and the risks are increasing because of climate change".
Because of the rate and strength at which the fires are burning and the amount of pollution entering the air, NASA scientists believe the heavy smoke will make "at least one full circuit around the globe" before returning to its origins in Australia.
The space agency used a satellite fleet to analyze the smoke and aerosols from the blazing fires in Australia.
PyroCb events represent a pathway through which smoke reaches the stratosphere at a height of more than 16 kilometers.
On January 8, the smoke had traveled "halfway around the Earth", said NASA, crossing South America to create a misty sky and create colorful sunrises and sunsets.
Earlier this year, New Zealand Police had to urge people to stop calling emergency services after smoke from the Australian fires turned the sky orange.
All the studies show links between climate change and increased frequency or severity of fire weather - periods with a high fire risk due to a combination of high temperatures, low humidity, low rainfall and often high winds - though some note anomalies in a few regions.
The Australian Open began today with qualifying matches on open courts.
Visitors to Melbourne should be aware of "very poor" air quality, according to Victoria's Environmental Protection Agency as a map of the areas of East Gippsland and Upper Murray in the state of Victoria shows how affected they are by active bushfires.
Effects were quickly visible during one of the qualifying matches when Slovenia's Dalila Jakupovic suffered a coughing fit while playing against Switzerland's Stefanie Vögele. C would help avoid further increases in the risk of extreme fire weather.
"[But] if it comes down to the conditions affecting the health of players, you have to consider it".
