Fred Pearce has an article on the IAC report in New Scientist.
The IPCC has tried hard to preserve the normal rules of scientific discourse and to explain continuing uncertainty, but it has been pushed towards simple sound-bite conclusions.

Sometimes, in the process, "could happen" has become "will happen", and analysis has veered close to advocacy. Journalists have been willing colluders.
Yup.
