RCP8.5 – another update

In case anyone is interested, Zeke Hausfather and Glen Peters have a Nature comment about the whole RCP8.5 issue. Unfortunately, they used misleading in the title, which seems to have produced an unfortunate headline on a BBC article. Otherwise, Zeke … Continue reading

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

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

The plausibility of RCP8.5

I’m on the train to Cambridge for a meeting that starts tomorrow. Since I had nothing better to do, I thought I would have a quick look at the RCP8.5 data. There’s been quite a lot of criticism of the … 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

But RCPs

Just as I thought I was out the ClimateBall Gods pull me back in. The “but RCP” flythe club got the best of me. For the time lost I found talking points for my Bingo. More on this project in … Continue reading

2019: A year in review

The end of another year, so time to do another round-up of this year’s posts. My main impression of 2019, unfortunatey, is that the climate debate is moved from disagreements with people who either deny climate change or the need … 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

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

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
