Man's role in climate change 'virtually certain' No myth ...

climate change has grown stronger and it is now ''virtually
certain'' that human greenhouse gas emissions trap energy that
warms the planet, according to a leaked draft of the next major
Intergovernmental Panel on Climate Change report. Prepared on
behalf of the United Nations every five or six years to
summarise climate change research, the panel report draws on
hundreds of peer-reviewed papers. The draft expresses even more
confidence than the 2007 report that changes being observed
across the planet are historically ''significant, unusual or
unprecedented''. It says that carbon dioxide is the biggest
cause of climate change, far outweighing natural causes. The
concentration of atmospheric carbon dioxide is the highest in
800,000 years. The draft document - due to be released next year
- was leaked by climate sceptic Alec Rawls
