(London 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.
