The Australian Bureau of Meteorology predicts temperatures will rise up to 10C by 2100, putting the country on course for a record of about five degrees Celsius (9.6F).
But a new study by the University of New South Wales suggests Australia will see the biggest change in temperatures ever.
“We’re going to see some very big changes in Australia,” Professor Ian Wilson from the university said.
“There will be a big drop in the average temperature, and we’re going be in the middle of a major warming phase.”
Professor Wilson said the study’s results will have a profound impact on the way the world is able to protect itself from climate change.
“Australia has been able to survive relatively well in the last century, but in the next 10 years or so we’re not going to be able to do it,” he said.
“That will be an enormous blow to the environment, to the people that live here, to our ability to do what we need to do to stop climate change.”
The study, published in the journal Nature Climate Change, examined the impact of two scenarios of global warming on Australia.
In the first scenario, global temperatures will continue to rise.
This would lead to a doubling of average global temperature, with temperatures forecast to rise from their current rate of 1.5C (2.8F) to 3.5 C (7.1F).
In a second scenario, warming rates drop, and temperatures fall to their present levels.
This means Australia will experience a 2C (4.7F) drop in average global temperatures by 2100.
Professor Wilson said it would be important to monitor these changes to make sure Australia can still keep a healthy and resilient population.
But the study said this was unlikely to be possible without an effective strategy to combat the impacts of climate change on the Australian economy.
Scientists predict Australia will be hit by climate change by 2050 “Australia will be the most vulnerable nation in the world in 2050,” Professor Wilson explained.
“And in many ways, the greatest economic and social risk of climate disruption in the 21st century is going to come from the very poor.”
Professor Wilson pointed out that a recent report by the Australian Bureau on Climate Change forecast Australia’s economy would be hit hard by the effects of climate changes.
According to the report, a 5C (7F)-level rise in average world temperature would leave Australia with a GDP of about $30 billion.
It also found Australia’s emissions would have a major impact on weather and climate extremes in Australia.
The research team used a variety of methods to examine the impact climate change would have on Australia’s population, industries, agriculture, transport and agriculture.
The researchers used a range of modelling techniques to find out how climate change might affect the country’s economy, agriculture and natural resources.
This study found that if global warming continues unabated, Australia could be hit the hardest by climate disruption.
While the impact on Australia will depend on many factors, the team concluded that the worst impacts could be felt in the agriculture sector, which accounts for more than 80 per cent of Australia’s agricultural output.
These include crop losses and crop failures, as well as drought and flooding.
Professor Wilson explained the impacts on Australia would be particularly pronounced for agricultural businesses and industries that relied heavily on the value of their land and its resources.
“If the value is diminished or the climate change goes away, they’re not likely to be there any more,” he told ABC News Breakfast.
He said it was important to remember the importance of the agricultural sector in Australia, particularly in light of the large number of jobs that would be lost if the climate changes were to continue unabated.
