CLIMATE CHANGE BACKGROUND
EARLY IN 2007 THE UNITED NATIONS INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE FOURTH ASSESSMENT REPORT HIGHLIGHTED THE SCALE OF SCIENTIFIC CONSENSUS THAT NOW EXISTS AROUND MANKIND'S INFLUENCE ON THE CLIMATE.
KEY FINDINGS INCLUDED;
The atmospheric concentration of Co2 in 2005 , 380ppm exceeds by far the natural range over the last 650,000 years, 180 to 300 ppm, as determined fron ice cores;
warming of the climate system is unequivocal, as is now evident from increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.
continued greenhouse gas emissions at, or above, current rates would cause further warming and induce many changes in the global climate system during the 21st century, scenarios for temperature inreases this century range from 1.8c to 6.4 c.
Following this, road map to a global deal on greenhouse gas emissions was agreed at the United Nations Climate Change Conference in Bali, with a view to it being finalised by the end of 2009.

Richard, that's all interesting and relevant but I have to ask, how can Labour justify building more roads and expanding airports in the knowledge that there needs to be urgent and radical changes to reduce our carbon emissions to prevent catastrophic climate change? Take a look at the reports on the sea ice changes at the North Pole and at the recent work by Jame Hansen on 350 being the maximum safe level.
