Curbing climate change 'unlikely'
By Richard Black Environment Correspondent, BBC News website
Rising concentrations of greenhouse gases may have more serious impacts than previously believed, a major new scientific report has said.
The report, published by the UK government, says there is only a small chance of greenhouse gas emissions being kept below "dangerous" levels.
It fears the Greenland ice sheet is likely to melt, leading sea levels to rise by seven metres over 1,000 years.
The poorest countries will be most vulnerable to these effects, it adds.
The report, "Avoiding Dangerous Climate Change", collates evidence presented by scientists at a conference hosted by the UK Meteorological Office in February 2005.
The conference set two principal objectives: to ask what level of greenhouse gases in the atmosphere is too much, and what are the options for avoiding such levels?
In the report's foreword, UK Prime Minister Tony Blair writes: "It is clear from the work presented that the risks of climate change may well be greater than we thought.
"It is now plain that the emission of greenhouse gases, associated with industrialisation and economic growth from a world population that has increased six-fold in 200 years, is causing global warming at a rate that is unsustainable."
