The world is now on track to experience more catastrophic damages from
climate change than in the worst-case scenario forecast by international
experts, scientists have warned.
The research, published in a prestigious US science journal, shows that between
2000 and 2004 the rate of increase in global carbon dioxide emissions from
fossil fuels was three times greater than in the 1990s.
That is faster than even the worst-case scenario modelled by the world's leading
scientists in the latest Intergovernmental Panel on Climate Change (IPCC)
reports, published over recent months, because the updated emissions figures
were not available in time to be included.
The climbing emissions mean that average global temperatures are now on track to
rise by more than four degrees this century - enough to thaw vast areas of
arctic permafrost and leave about 3 billion people suffering from water
shortages, including in Australia.
