Scenario use in climate research

If you’ve been following the blog for a while, you will be aware that I’ve commented on a number of occasions about the whole RCP8.5 issue. You may also be aware that one of the chief protagonists in that whole … 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

Stocks and Flows

Sitting at home waiting for a delivery, so just a quick post. There’s been a new narrative, on social media at least, that we may be heading for a plateau in global emissions. The suggestion, then, is that we are … Continue reading

Worst case scenarios, or not?

I’ve been thinking a bit more about the debate around high emission scenarios, which I found rather frustrating. I think it’s an important issue, but the manner in which some people choose to frame this does make it difficult to … 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

Public criticism

I came across an article about media and the game of climate change denialism. The basic message is that the media should better reflect the nuances in the climate change debate and should avoid presenting it as a debate between … 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

Representative Concentration Pathways

I’ve noticed a fair amount of dicussion about the Representative Concentration Pathways (RCPs) varying from they’re scientific fraud, they’re overly optimistic, to the details are being hidden so the IPCC can’t be trusted. I haven’t actually paid to much attention … Continue reading

Is this the latest tactic?

Willard has a contrarian matrix that is intended to illustrate the evolution of contrarian arguments. It certainly appears that it evolves with time, varying from it’s not happening, it’s happening but it’s slow, it’s stopped, it’ll be good, there are … Continue reading
