Well I think climate change is objective fact, but this link is wildly emotional.
"Final Warning" "act now or it's too late" sounds like a late-night infomercial selling me something.
If I were running the report I'd try to write it in a manner that is scientific and thus emotionally indifferent to every outcome. Science doesn't care whether any special dies or not (humans or not). If you can't look at climate science with an indifference to the death of the species, you probably can't run statistics neutrally, which gives a lot of room for doubt (fair or not).
If you want to criticize this article that's fine, but you are blaming the IPCC authors for this Guardian reporter's phrasing. If you read the report you'll find it was written in a scientific and objective manner, and as emotionless as possible while using human language. You will probably find it boring to read even the extremely shortened "Summary for Policymakers".
The associated press release uses stronger language, but it still pretty objective if you accept the emotional axiom that "avoiding death and destruction is good".
