Big business is paying for sceptics to undermine IPCC report: UN.

Guardian: “Big companies are paying contrarians to undermine the work of climate scientists, according to a top UN official speaking before the release of a landmark review of climate science this weekby international researchers next Friday.”Halldór Thorgeirsson, a director who reports to the head of the UN body that governs the on-going high level international climate negotiations, said that scientists would need to be prepared for a counter-blast from sceptics.
“Vested interests are paying for the discrediting of scientists all the time. We need to be ready for that,” he said.
His outspoken views will set the tone for a fractious meeting of the world’s leading climate scientists, kicking off on Monday in Stockholm, that will set out the evidence that the world’s governments use when formulating policies to deal with global warming for decades to come. More than 800 scientists have contributed to the report, the final details of which will be hammered out in a gruelling four-day session next week.
According to a draft of the “Summary for Policy Makers” dated June , seen by the Guardian– the most important part of the document – the scientists will argue that the evidence points to 95% certainty that climate change is occurring and is caused mainly by greenhouse gases released by humans – up from 90% certainty in the previous 2007 report. The 53 page document, seen by the Guardian which includes a note saying “do not cite, quote or distribute” says that levels of greenhouse gases in the atmosphere are now greater than at any time in the last 800,000 years, based on ice cores and other evidence, and the incidences of extreme rainfall are increasing, with rainfall likely to increase in the north but to decrease in the subtropics. The draft outlines evidence of “large-scale warming resulting primarily from anthropogenic increases in greenhouse gas concentrations”. It says that if warming is to be limited to less than 2C in future, more than half of the carbon that can be emitted to hold to that goal has already been poured into the atmosphere.”
