The IPCC AR6 WGI report has been released [link]

I’m reading it now. So far I’ve read the Summary for Policy Makers, the Technical Summary and Chapter 1.

Detailed comments will be forthcoming later in the week. But there are some new approaches that represent a marked break with the AR5. Some are good.

Roger Pielke Jr has a thread of comments, that is well worth reading

Very important:
"IPCC is neutral with regard to the assumptions underlying the SSPs"

So IPCC recognizes that 8.5 scenarios have "low likelihood" but nonetheless choose to remain "neutral" with respect to scenario assumptions

Lots of breathless alarm in the media.

More soon.
