No amount of CO2 cuts will satisfy believers...

Why bother with any cuts - what they want is just impossible....

At the end of last year Government advisers recommended the country cuts emissions by at least a third by 2020 to stop climate change.

However scientists at the Tyndall Centre of Climate Change have warned that the evidence used to calculate the targets needed is "misleading" and the cuts will have to be much larger to stop temperatures rising above a level that causes extreme weather events, droughts and food shortages.

This would mean the UK would have to commit to further reduce carbon emissions by burning less fossil fuels in energy and transport.

The warning comes after an emergency meeting of international scientists in Copenhagen warned the affects of global warming will be much worse than previously thought and was welcomed by environmentalists as further evidence that politicians must act.
