An Australian scientist, Tim Flannery, after reviewing the technical data for an upcoming report on climate change says that greenhouse gas emissions have exceeded a level that they were not expected to reach for at least another decade.
Flannery 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. This is "....beyond the worst-case scenario as we thought of it in 2001," when the last major IPCC report was issued.
