And then there's physics: Climate Change – The Facts

I watched BBC One’s Climate Change – The Facts, narrated by David Attenborough. A pity about the title, as it’s the same as a book with authors that include Anthony Watts, Nigel Lawson and James Delingpole, but I thought it …

And then there's physics: Six years

I’ve just been reminded by WordPress that this is the sixth anniversary of me starting this blog. I’m somewhat amazed that I’ve kept it going that long. I am, however, finding it more and more difficult to find things to …

And then there's physics: Post-normal science

I’ve been reading a paper by Daniel Sarewitz, that was being highlighted by Jane Flegal on Twitter. The paper is called Of Cold Mice and Isotopes Or Should We Do Less Science? There’s quite a lot that could be said …

And then there's physics: Models and scenarios

I was following, or trying to, a Twitter discussion about models and scenarios. It was – I think – about models that forescast technology development, and you can find it here if you’re interested. I didn’t entirely follow it, but …

And then there's physics: Existential threat?

I had a discussion with someone recently who asked if climate change really was an existential threat for humans. I responded that it wasn’t. However, I added that this didn’t mean that it couldn’t be severely disruptive or that it …

And then there's physics: An updated Bayesian climate sensitivity estimate

I thought I would update my Bayesian climate sensitivity estimate, given the comments I received (peer-review in action). Based on James’s comment, I’ve removed the noise term and am now using the aerosol forcing as the forcing uncertainty. Based on …

And then there's physics: An attempt to do a Bayesian estimate of climate sensitivity

I’ve been spending some time working on a Bayesian estimate for climate sensitivity. This is somewhat preliminary and a bit simplistic, but I thought I would post what I’ve done. Essentially, I’ve used the Markov Chain Monte Carlo method to …

And then there's physics: Jonathan’s Carrot and Stick

Jonathan Gilligan is Associate Professor of Earth and Environmental Sciences and Associate Professor of Civil and Environmental Engineering at Vanderbilt University, or so starts his media blurb. To me, Jonathan is the ClimateBall fellow I met at Keith’s ages ago. …

And then there's physics: Public involvement in science

I had a brief discussion on Twitter yesterday about science communication, in which the other party seemed to be suggesting that we should recognise that lots of science comes up from the streets and that we should have more people …

And then there's physics: The BBC’s lack of balance

Just discovered that a new BBC Scotland news programme (The Nine) decided that it would invite Andrew Montford on to discuss the Youth Strike for Climate. Fortunately, no one else was willing to appear with him, so the segment didn’t …

And then there's physics: Open thread: Youth strike for climate

Since I haven’t had a post for a few days, I thought we could have an open thread about the youth strike for climate. I mostly think it’s quite a positive thing; it’s young people whose future is at stake …

And then there's physics: 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 …

And then there's physics: The Honest Broker

In discussions about science and policy, it is quite common for people to refer to The Honest Broker, a book by Roger Pielke Jr. I realise that it is now a little old, but I’ve only just had the chance …

And then there's physics: Climate change risks

I thought I would briefly mention a paper, by Simon Sharpe, that is currently under review and that discusses how we should present climate risks. It was highlighted by Steve Forden on Twitter and suggests that climate risks should be …

And then there's physics: Mario’s Room

Marie Kondo might be onto something. Her method inspires millions to unclutter homes and lives. She divides belongings into five categories: clothes, books, papers, miscellanea, and mementos. (So much the worse for artisans and musicians.) After having gathered each item …

And then there's physics: Only Connect

You may have heard of the cumulative temperature increases plateauing between 1998 and 2013. “But Da Paws” was all the rage around 2012 in the Contrarian Matrix – recall for instance when David Rose became Judy’s megaphone. Then it subsided: …

And then there's physics: Climate scepticism in the UK

I came across a book called Climate Change Scepticism: A transnational ecocritical analysis, by Greg Garrard, Axel Goodbody, George Handley, and Stéphanie Posthumus. The reason I found it interesting is that it includes a chapter on Climate Scepticism in the …

And then there's physics: Swans on ice
