According to Tim Flannery, the upcoming version of the IPCC report will contain new data showing that the level of greenhouse gases in the atmosphere has already reached critical levels.

He said the data showed that the amount of carbon dioxide and other greenhouse gas concentrations 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.
If Flannery is correct, this is yet another sign that global warming is exceeding the worst IPCC projections. That's very worrying, to say the least.
