Sydney, Australia - Strong worldwide economic growth has accelerated the level
of greenhouse gas emissions in the atmosphere to a dangerous threshold scientists
had not expected for another decade, according to a leading Australian climate
change expert.
Scientist Tim Flannery told Australian Broadcasting Corp. that an upcoming
report by the U.N. Intergovernmental Panel on Climate Change will contain new
data showing that the level of climate-changing gases in the atmosphere has
already reached critical levels.
Flannery is not a member of the IPCC, but said he based his comments on a thorough
review of the technical data included in the panel's three working group reports
published earlier this year. The IPCC is due to release its final report synthesizing
the data in November.
"What the report establishes is that the amount of greenhouse gas in the atmosphere
is already above the threshold that can potentially cause dangerous climate
change," Flannery told the broadcaster late Monday. "We are already at great
risk of dangerous climate change, that's what these figures say. It's not next
year or next decade, it's now."
Flannery, whose recent book "The Weather Makers: How Man Is Changing the Climate
and What It Means for Life on Earth," made best-seller lists worldwide, said
the data showed that the amount of carbon dioxide and other greenhouse gas emissions
had reached about 455 parts per million by mid-2005, well ahead of scientists'
previous calculations.
"We thought we'd be at that threshold within about a decade, that we had that
much time," Flannery said. "I mean, that's beyond the limits of projection,
beyond the worst-case scenario as we thought of it in 2001," when the last
major IPCC report was issued.
The new data could add urgency to the next round of U.N. climate change talks
on the Indonesian island of Bali in December, which will aim to start negotiations
on a replacement for the 1997 Kyoto Protocol, which expires in 2012.
Flannery said that the recent economic boom in China and India has helped to
accelerate the levels of carbon dioxide and other greenhouse gases in the atmosphere,
but strong growth in the developed world has also exacerbated the problem.
"It's a worldwide issue. We've had growing economies everywhere, we're still
basing that economic activity on fossil fuels," he said. "The metabolism of
that economy is now on a collision course clearly with the metabolism of our
planet."
A spokesman for Australia's IPCC delegate, Ian Carruthers, said he was not
available to comment on the report because it was still in draft form.
