ReutersGreenhouse gas emissions hit danger mark: scientistTue Oct 9, 2007 1:44am EDT

SYDNEY (Reuters) - The global economic boom has
accelerated greenhouse gas emissions to a
dangerous threshold not expected for a decade and
could potentially cause irreversible climate change,
said one of Australia's leading scientists.
Tim Flannery, a world recognized climate change
scientist and Australian of the Year in 2007, said
a U.N. international climate change report due in
November will show that greenhouse gases have
already reached a dangerous level.
Flannery said the Intergovernmental Panel on Climate
Change (IPCC) report will show that greenhouse gas
in the atmosphere in mid-2005 had reached about
455 parts per million of carbon dioxide equivalent
-- a level not expected for another 10 years.
"We thought we'd be at that threshold within about
a decade," Flannery told Australian television late
on Monday.
