RCP8.5 – another update

Posted on January 31, 2020 by ...and Then There's Physics

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 →

Worst case scenarios, or not?

Posted on October 6, 2019 by ...and Then There's Physics

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

Posted on March 10, 2019 by ...and Then There's Physics

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 →

What bothers, and confuses, me about climate change

Posted on January 6, 2019 by ...and Then There's Physics

Since this blog is mainly a place for me to express my views, I thought I would try explain something that bothers, and confuses, me about the whole climate change issue. Maybe others feel the same as I do, maybe … Continue reading →

The plausibility of RCP8.5

Posted on December 2, 2018 by ...and Then There's Physics

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 →

A bit more about carbon budgets

Posted on September 27, 2017 by ...and Then There's Physics

I’ve been mostly at home today since we had a power cut at work and the site ended up being closed. So, I thought I would post a few more thoughts about the Millar et al. 1.5oC carbon budget paper. … Continue reading →

Public criticism

Posted on January 6, 2017 by ...and Then There's Physics

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 →

Emission reductions, negative emissions, and overshoots

Posted on August 8, 2016 by ...and Then There's Physics

I was wanting to briefly discuss a paper I ran across that looks at What would it take to achieve the Paris temperature targets? The basic idea is to develop emission pathways that depend on three basic parameters; the time … Continue reading →

RCPs as scenarios

Posted on December 17, 2015 by ...and Then There's Physics

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 →

Censoring their own research?

Posted on November 30, 2015 by ...and Then There's Physics

This is going to be my last post about the whole 2oC pathways issue, I promise 🙂 I was wanting, however, to discuss this Washington Post article called The magic number. It quotes Kevin Anderson, whose work I’ve discussed before. … Continue reading →
