With the IPCC report not yet published, there is already heated debate about what it will say, and about the implications of its findings for human development.

The scientists' statement is unequivocal, and is not based on whatever the IPCC may publish. They say: "The body of evidence indicating that our civilisation has already caused significant global warming is overwhelming."

The statement comes from 12 members of the recently established Earth League, which describes itself as "a voluntary alliance of leading scientists and institutions dealing with planetary processes and sustainability issues".
