Australia faces a rise in temperature of potentially more than 5 degrees Celsius (9 degrees Fahrenheit) by the end of the century, an increase that would outpace global warming worldwide, the country's national science agency said on Tuesday.

 

In its most comprehensive analysis yet of the impacts of climate change, the Commonwealth Scientific and Industrial Research Organization (CSIRO) painted a worst-case scenario of a rise of up to 5.1 degrees Celsius by 2090 if there are no actions taken to cut greenhouse emissions.

 

"There is a very high confidence that hot days will become more frequent and hotter," CSIRO principal research scientist Kevin Hennessy said. "We also have very high confidence that sea levels will rise, oceans will become more acidic, and snow depths will decline."

 

The dire warning from the government-funded agency is at odds with the official line from Australian Prime Minister Tony Abbott, who in 2009 declared the science of climate change was "crap".

 

One of the world's biggest carbon emitters per capita, Australia has declined to join the United States, Japan, France and others in contributing to the United Nations' Green Climate Fund.

 

Abbott has instead committed A$2.55 billion ($2.21 billion) to a domestic initiative to reduce the country's emissions by 5 percent below 2000 levels by 2020.

 

The new research by CSIRO and the Bureau of Meteorology, using some 40 global climate models, has Australia warming at a greater rate than the rest of the world.

 

The 5.1 degree Celsius projection for 2090 is at the top end of a range starting at 2.8 degrees Celsius and is dependent on how deeply, if at all, greenhouse gas emissions are cut. The world average is for an increase of between 2.6 degrees Celsius and 4.8 degrees Celsius.

 

The report said the annual average temperature in Australia would likely be up to 1.3 degrees Celsius warmer in 2030 than the average experienced between 1986 and 2005.
