The UK Telegraph reports that the forthcoming report of the UN’s Intergovernmental Panel on Climate Change will report there is greater certainty about the connection between anthropogenic emissions of greenhouse gases and global temperature, while offering a slightly reduced estimate of human impact on global climate.
The UN Intergovernmental Panel on Climate Change says there can be little doubt that humans are responsible for warming the planet, but the organisation has reduced its overall estimate of this effect by 25 per cent.
In a final draft of its fourth assessment report, to be published in February, the panel reports that the level of carbon dioxide in the atmosphere has accelerated in the past five years. It also predicts that temperatures will rise by up to 4.5 C during the next 100 years, bringing more frequent heat waves and storms.
The panel, however, has lowered predictions of how much sea levels will rise in comparison with its last report in 2001.
Climate change sceptics are expected to seize on the revised figures as evidence that action to combat global warming is less urgent.
Scientists insist that the lower estimates for sea levels and the human impact on global warming are simply a refinement due to better data on how climate works rather than a reduction in the risk posed by global warming.
UPDATE: Tim Lambert explains why he thinks the Independent is mistaken.
