Slow travel

If you’ve been following my Twitter threads, you should be aware that I’m just back from a trip to Austria that I decided to do via train. The meeting was for a collaboration that developed after I spent some time…

Sherelle’s Bingo Squares

Yesterday Michael Brown alterted me (see “@nevaudit”) of this contrarian editorial: Can you OD on #climate bingo @nevaudit? This is only a partial list – watch out for the hit of Galileo. https://t.co/GY6m5aqmeA— Michael Brown (@MJIBrown) January 24, 2020 As…

Consensus messaging, an update

If you’re a regular follower of this blog, you’ll know that some of the most active threads have concerned the scientific consensus about climate change and, more specifically, the issue of consensus messaging. Recently, a new book has been released…

Zharkova et al.: an update

Last year I wrote a couple of posts about a paper by Valentina Zharkova and colleagues, which suggested that global warming was partly due to the Earth moving closer to the Sun as the Sun moves around the Solar System…

Another CMIP6 climate sensitivity constraint

I thought I would follow up yesterday’s post with one that highlights another paper that looks at CMIP6 climate sensitivity. It’s a paper by Femke Nijsse, and colleagues, and considers [a]n emergent constraint on Transient Climate Response from simulated historical…

Climate sensitivity in CMIP6 GCMs

Anyone who is aware of what’s going on in climate science should have heard that the latest generation of climate models, known as CMIP6, seem to be suggesting a somewhat higher climate sensitivity than suggested by the previous CMIP5 models.…

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…

Listen to the (political) science

I’ve been meaning to post a review of 2019, but wanted to first comment on something else. I quite often see criticism of how some people approach the issue of climate change. For example, in the Guardian yesterday, there was…

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…

Jens’ Bayesian Models

[W] Hello. How’s everything? [J] Things are good, thanks Busy December, but that’s par for the course. I hope you’re well also. [W] I have the flu, but hope to survive against all odds. That’s you: https://oxfordmartin.ox.ac.uk/people/dr-jens-koed-madsen/ [J] Ah, the…

Cruel Crazy Beautiful World

Given the disappointing news of the last day or so, I thought I would highlight a song that I find suitably reflective. You’ve got to wash with the crocodile in the river You’ve got to swim with the sharks in…

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…

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…

Tipping points/elements

There has been quite lot of discussion recently about climate tipping points, or tipping elements. It’s mostly motivated by a recent Nature comment suggesting that Climate tipping points [are] too risky to bet against. The suggestion is that some the…

Methane

I’ve always been a little confused as to why so much attention is paid to methane emissions. It’s short-lived, so isn’t it maybe somewhat less important that CO2 emissions, which are long-lived? One reason it is quite prominent is because…

Science and Technology Studies Podcast

I’ve been trying to listen to more podcasts, and came across a new one that might be of interest to my readers. It’s called The Received Wisdom with Shobita Parthasarathy and Jack Stilgoe. Both are researchers in Science and Technology…

Climategate

Climategate is a topic I’ve rarely discussed on this blog. Mostly because it’s clear that it’s not possible to have a constructive discussion with those who have different views about its significance. However, since I watched the BBC show about…

Science is a messy process

I was invited to speak at a Contemporary Climate meeting in Edinburgh’s School of Geosciences. It was really nice to talk face-to-face with people about some of the topics I find interesting. We covered aspects of blogging and social media,…

Contrarian Models

We need better ClimateBall contrarians. Perhaps they need better contrarian role models. Let’s find them, if only for our own sake. Here are five of mine. Fred Rogers was a TV show producer, a comedian, an author, a puppeteer, a…

Depolarising the debate?

I’ve always been a little puzzled by the (mostly) social scientists who seem to argue that to develop effective climate policy we should stop using labels, be depolarizing the debate, and should prioritise civil disagreements. It’s not that I object…

Journalistic norms for bloggers

I thought I would quickly advertise a recent paper called ““The truth is not in the middle”: Journalistic norms of climate change bloggers. It’s by Christel van Eck, Bob Mulder, and Art DeWulf, who are also involved in the survey…

Societal tipping points

Noami Oreskes and Nicholas Stern have a New York Times Opinion piece called Climate Change will cost us even more than we think. Some are very critical, others are a little more circumspect. I, on the other hand, think that…

Flight free talk

I gave my first ever public climate science talk at a Flight Free event in Edinburgh. If you’re interested in seeing my talk slides, you can download them here. The idea behind Flight Free is to encourage people to pledge…

The GRRRRROWTH Institute

Posit an opiniator O* from the Super Wonderful Punditry think tank SWP. Deadlines displease him. The international community failed to meet so many since 1995 that such call becomes self-defeating, or so O* worries. To interpret IPCC deliverables, time for…

Stepping outside my comfort zone

I noticed that I was getting some flack in the comments on another climate blog (to which I won’t link), with some commenters claiming I’d lost whatever credibility I had. This seemed a little surprising, as I didn’t think I…

2025?

One of the demands from Extinction rebellion is that the [g]overnment must act now to halt biodiversity loss and reduce greenhouse gas emissions to net zero by 2025. This has been criticised as being so unrealistic as to potentially damage…

A survey of blog audiences

A while ago, I was interviewed by Christel van Eck, who is a PhD student at Wageningen University & Research. It was for a project about the journalistic norms adhered to by bloggers. There should be a paper appearing quite…

Extinction rebellion

I’ve written about extinction rebellion before. Although I think they get some of the science wrong, and some of their demands seem unrealistic (we can’t get emissions to zero in 7 years), they are having an impact. We keep getting…
