SYDNEY - Australia faces a possible 300 percent increase in extreme bushfires by 2050 unless world leaders can agree to dramatically cut greenhouse gas emissions, a new report said on Thursday.
The report, commissioned by Australia's firefighters and environmental group Greenpeace, said the failure of U.N. climate talks in Copenhagen to agree on a treaty to tackle climate change had left Australia facing future catastrophic bushfire seasons.
The "Future Risk: Battling Australia's Bushfires" report comes only days before the Copenhagen Accord Jan 31. deadline for nations to announce emissions reduction targets.
"Bushfire conditions are clearly changing and there is strong evidence that global warming is making Australia's climate more bushfire-prone," said Jim Casey, secretary of the Fire Brigade Employees Union in Australia's New South Wales state.
"Bushfire seasons are getting longer and fires are becoming more frequent and intense. We have the power to reverse this trend or we can shrug our shoulders, do nothing and play Russian roulette with our lives," Casey said in releasing the report.
Bushfires are a natural phenomenon in Australia, due to the hot, dry climate.
Australia's most deadly bushfires occurred in February 2009 and were blamed on a decade long drought and extreme heatwaves. The "Black Saturday" infernos killed 173 people and destroyed thousands of homes in the southern state of Victoria state.
This Australian summer has again seen extreme bushfires.
THREE SCENARIOS
The bushfire report, based on studies by Australia's peak scientific body the Commonwealth Scientific & Industrial Research Organization (CSIRO), painted three scenarios:
* Under a global climate treaty based on current promises to cut greenhouse gases, Australia's mean temperature would rise by 2 degrees Celsius above 1990 levels by 2050.
This would double the number of severe bushfire days in Australia's most populated southeast corner by 2050. Severe bushfire days would occur once every six months in Sydney.
* Without a legally binding climate treaty the upper forecast temperature rise of 6.4 degrees Celsius globally, by the end of the century, would see Australia experience a 2.8 degree Celsius rise above 1990 levels by 2050.
This is the worst case scenario for Australia which could see up to a 300 percent rise in extreme bushfire days by 2050.
* Under a global treaty with dramatic greenhouse gas cuts, which could see Australia halve its greenhouse emissions by 2050, extreme bushfire danger days would rise by only 8-17 percent.
"Future bushfire danger in Australia will depend heavily on how fast and by how much we act to tackle global warming," said the report.
"The best chance of avoiding a high global warming scenario is through a fair, ambitious and legally binding international treaty to cut emissions," it said.
The firefighters and Greenpeace called on the Australian government to dramatically increase its greenhouse emissions target cuts, but Climate Change Minister Penny Wong on Wednesday announced Australia would stick to its 5 to 25 percent emissions cut range under the non-binding "Copenhagen Accord".
Wong said any decision to opt for a 15 or 25 percent target depended in part on strong steps by India and China to reduce the growth of their greenhouse gas emissions.
"This report shows that unless governments ramp up their targets for cutting greenhouse emissions, we'll be facing more frequent bushfire tragedies on an even greater scale," said Casey.

Climate change to triple Australia fire danger: report
Yahoo News 28 Jan 10;
SYDNEY (AFP) – Climate change could more than triple the risk of catastrophic wildfires in parts of Australia, a top environmental group warned Thursday, almost a year since savage firestorms that killed 173 people.
Greenpeace warned that, without a new climate treaty to replace the Kyoto Protocol, the frequency of severe fire danger in drought-parched southeastern Australia would grow threefold by 2050.
"Catastrophic" conditions similar to those ahead of February's so-called "Black Saturday" wildfires which killed 173 people in towns around Melbourne would occur once every three years, instead of once in every 33.
"The frequency of catastrophic fire danger could increase more than tenfold in Melbourne, and the number of total fire ban days could triple in Sydney, Adelaide and Canberra by 2050," according to a Greenpeace report entitled "Future Risk."
If targets for emission cuts proposed by world leaders at December's Copenhagen summit were adopted in a new global treaty, southeastern Australia would still face at least a doubling of severe fire risk, Greenpeace said.
"If we do nothing to address climate change we are knowingly placing more lives and property at risk," said Greenpeace CEO Linda Selvey.
According to the report temperatures in Australia had warmed an average 0.9 degrees Celsius (33.6 F) since 1950, with the greatest intensification of heat in the country's east, which was accompanied by markedly declining rainfall.
"Hotter, drier weather is a recipe for bushfire disaster in regions of Australia home to the majority of the population," it said, adding that the changing climate had "noticeably" prolonged the annual fire season.
The February 7 Black Saturday fires were the worst natural disaster in Australia's modern history, with one expert likening their intensity to the energy produced by 1,500 Hiroshima atomic bombs.
More than 2,000 homes were destroyed, killing 173 people and injuring more than 400.
Australia this week reiterated its Copenhagen goal for emissions cuts of between five and 25 percent of 2000 levels by 2020, depending on commitments by other nations, and said they would be formally submitted to the UN.
