RCP4.5/SSP2-4.5
I messed up something on Twitter so, of course, I now have to write a blog post. There seems to be this narrative developing that we’re either tracking well below RCP4.5/SSP2-4.5, or that it’s now a plausible high-end pathway, and … Continue reading

Scenarios
Just before the release of the IPCC’s AR6 WGIII report (Mitigation of Climate Change) Joeri Rogelj had a Carbon Brief guest post on how not to interpret the emission scenarios in the IPCC report. It might have been to try … Continue reading
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
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
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
