The most important report on the science of climate change for six years is set for release on Friday 2 February, and leaks suggest it will be an alarming read.
The minimum predicted temperature and sea level rises will jump, according to media reports, while the blame will be pinned firmly on greenhouse gas emissions from human activities. Its leading line is expected to be "there is a 90% chance humans are responsible for climate change", mostly due to the burning of fossil fuels.
That contrasts with the last version of the Intergovernmental Panel on Climate Change's report, issued in 2001, which concluded there was a 66% chance that humans were responsible for rising temperatures.
The new IPCC report is expected to predict that temperatures will rise by 2.0°C to 4.5°C by 2100. The 2001 report gave a range of 1.4°C and 5.8°C – a wider range and a lower minimum rise.
Similarly, the new report is believed to predict that sea-levels will rise by between 28 centimetres and 43 cm by 2100, compared with the 2001 prediction of between 9 cm and 88 cm (2.54 cm = 1 inch).
But even these changes are regarded by some as a conservative estimates arrived at by consensus. "If the IPCC comes out with significantly less than 100 cm of sea level rise, there will be people in the science community saying we don't think that's a fair reflection of what we know," said Bob Corell, chairman of the Arctic Climate Impact Assessment, speaking to Associated Press.

plus or minus 90%. Whose orphice did they pull that number out of? This 100% pure non-scientific bullshit.
Oddly, their mantra was always the debate was over. Saying there is only a 90% chance that man is responsible for global warming is actually a downgrade from the old rhetoric.
