The never-ending RCP8.5 debate

I think my New Year’s resolution is going to be to not talk about RCP8.5. However, I think I will briefly summarise the state of the never-ending debate. I thought we’d reached a bit of a breakthough when Zeke Hausfather … Continue reading

Different perspectives

I’ve been reflecting a little on some of the recent discussions I’ve had, mostly on Twitter, with those who have more expertise in emission scenarios, and energy systems, than in physical climate science specifically. I’ve found it a somewhat frustrating … Continue reading

High emission scenarios

I thought I might briefly reflect, again, on the whole RCP8.5 discussion. In case anyone missed it, there has been a lengthy online discussion about RCP8.5, which is a concentration/forcing pathway that leads to a change in forcing of 8.5 … Continue reading

Sigh

There’s been a rather contentious Twitter thread about RCP8.5, a concentration/forcing pathway I’ve discussed before. It started with a claim that it was “bollox” followed by a suggestion that it was mainly used for generating headlines, scaring gullible folk and … Continue reading

The Plausibility of RCP8.5 – part II

A while ago I wrote a post about the plausibility of RCP8.5. It was essentially pointing out that there are a range of emission pathways, and hence cumulative emissions, that could lead to an RCP8.5 concentration pathway. Some of them … Continue reading

RCP8.5

There’s been a lengthy discussion on Twitter about RCP8.5. I think it was initiated by Roger Pielke Jr, who continues in his campaign to police the scientific community: RCP 8.5 is by far the favorite in climate impact studies (graph).I … Continue reading

RCPs as scenarios

Fabius Maximus has a guest post on Climate Etc. in which he focuses on RCP8.5. RCP8.5 is a Representative Concentration Pathway (RCP) that leads to a change in forcing of 8.5Wm-2 in 2100. Focusing on this particular RCP seems to … Continue reading
