Intergovernmental Panel on Climate Change

The Intergovernmental Panel on Climate Change (abbreviated IPCC) predicted that up to 3.5 billion people could be directly and negatively affected by climate change. Its report led to the Kyoto Protocol.

Since then however some of its conclusions, in particular those dismissing worries about the huge West Antarctic Ice Sheet disintegrating, which would raise sea levels around the world by 16ft. The number of people directly affected would rise greatly under these assumptions.

Head of the British Antarctic Survey, Professor Chris Rapley, wrote "The last IPCC report characterised Antarctica as a slumbering giant in terms of climate change. I would say it is now an awakened giant. There is real concern." - http://news.scotsman.com/latest.cfm?id=149432006

A British report, released on a book, Avoiding Dangerous Climate Change, collates evidence of "large-scale irreversible disruption if temperatures rise above 3C - well within the range of climate change projections for the century."
