What does the Vostok ice core tell us?

Euan Mearns, who runs a blog called Energy Matters, had a post in 2014 about The Vostok ice core: Temperature CO2 and CH4. This post has apparently had 8000 reads, is probably one of the most read texts on the…

Peddling

https://neverendingaudit.tumblr.com/post/150362283819 Peddling is arguably the most favorite way for contrarians to lob factoids behind enemy lines. Once a door opens, peddlers block it with their foot and dispatch their sale pitches. Peddled talking points seldom matter to the topic at…

Climate communication

Doug McNeall recently gave a talk about surviving the climate communication environment, which he discusses in this post. A lightly edited version of the slides are available here. The slides, of course, don’t tell you precisely what was said in…

Lukewarmers resurgent

I’ve noticed a slight resurgence in those claiming to be lukewarmers and trying to argue that this is some kind of reasonable middle ground. I’ve written about lukewarmers before, but the basic issue with the lukewarmer argument is that they…

The crisis of free speech in higher education

I came across an interesting post by Mark Carrigan called the (coming) crisis of free speech in the digital university. The underlying issue is the suggestion that there is a crisis of free speech in higher education. This is related,…

Trump and Paris

So, Trump has decided to withdraw from the Paris climate accord. It’s not really a great surprise, but disappointing nonetheless. The thing that gets me is how inconsistent the arguments for leaving seem to be. I particularly liked David Roberts’s…

The enhanced greenhouse effect

This is really just an opportunity to write a little bit about science, and to advertise other people’s work. There are some who suggest that adding CO2 to the atmosphere can’t lead to warming because CO2 absorption is saturated. This…

No, peer-review isn’t tainted!

It seems that some climate “skeptics” are revelling in the publication of another hoax paper. In this case a paper called The conceptual penis as a social construct, which has now been withdrawn (an archived version is here). The authors…

Emission pathways

Credit: Su et al. (2017) I’m always a little concerned about writing about economics/policy, because I don’t have any specific expertise and find myself easily confused. However, I thought I would briefly discuss a figure that Glen Peters posted on…

Seems OMICS International will publish anything

A new paper in the Environment Pollution and Climate Change journal (published by OMICS International) claims to have provided a refutation of the climate greenhouse theory. It’s, of course, utter nonsense, so I’m not planning on saying much. What is…

Climate and conflict

I watched a talk by Clionadh Raleigh on Climate Violence (see video at the end of the post). I’m still not entirely sure what to make of it, but I certainly found it quite thought provoking. The bottom line was…

Freedom Fighters

I’ve been using the Freedom Fighter label for a while now. It’s more evocative than libertarian, less pejorative than market fundamentalist, and furthermore alliterative. In the following note, I am pleased to report some evidence that Freedom Fighters may become…

Out of the lab and into the field?

This is probably going to be another of those rather confused posts, which doesn’t really say much and in which I illustrate my own confusion, more than anything else. I’ve been reading (a few times, now) a Nature article by…

97% vs 99.99%

We’ve just had another consensus paper published. The paper is called Does It Matter if the Consensus on Anthropogenic Global Warming Is 97% or 99.99%? (pre-print here). The lead author is Andy Skuce, who has a nice post about it.…

Isn’t this also kind of an own goal?

Yesterday’s post was about the recent New York Time’s (NYT) Op-Ed by Bret Stephens. Some people, including a number of climate scientists, are sufficiently disappointed in this that they’re publicly cancelling their NYT subscriptions. Tom Yulsman, a journalism professor and…

We might not be certain, but…..

Bret Stephens, the newly appointed Op-Ed writer for the New York Times, has released his first column to much criticism. It’s a rather strawman-laden column in which he essentially argues that it’s okay to doubt climate science, and/or climate policy,…

The War on Science … Not?

For the last week or so, I’ve been reading, and re-reading, an article called perspective: It’s not a war on science. The reason I’ve been doing this is because I noticed that a number of people seemed to regard it…

Red Team vs Blue Team

Having some kind of Red Team exercise, to test and challenge the climate science consensus, seems to be gaining a small amount of momentum. Steve Koonin (who I have discussed before) has an article in the Wall Street Journal called…

A day of activism … sort of

I discovered via Rachel’s blog that today was Pedal on Parliament 2017 (Scotland, only). Rachel has a new post about the event in Abereen. It’s also the day for the Marches for Science. So, we thought we’d go and spend…

Marches for Science

Tomorrow is the day of Marches for Science. The idea of a march for science has somewhat divided people, although along rather predictable lines. There’s concern that it will be seen as politicising science. There’s concern that it will be…

The Earth from Saturn

NASA’s Cassini spacecraft has taken an image of the Earth, through the rings of Saturn. I don’t think I really need to say anything more. Credit: NASA/Cassini…

Reconciling ECS estimates – again

I’m heading home after giving a public talk, and have a bit of time to write about the recent Armour paper Projection and Prediction: Climate Sensitivity on the rise. It’s basically another attempt to reconcile energy balance estimates for climate…

State of the blog

Since I’ve now been running this blog for four years, I thought it might be an opportunity to consider if I should make any changes. Things have certainly got a little quieter, which might simply be because I’m writing less,…

Four years!

WordPress reminded me that I started this blog 4 years ago today. Not really sure what to make of that. I’d like to think that I’d have some kind of insights to share, but I don’t really think I do.…

Emissions slowdown

I thought I would post this video of Glen Peters discussing the three years we’ve just had in which there has been near-zero growth in emissions. You can use a Kaya-like identity to try and understand what might be causing…

Toys, pram, out!

It seems that Roger Pielke Jr is having a bit of a rant on Twitter about an interview Michael Mann gave about the recent Congressional Hearings. He accuses Michael Mann of lying about him and also suggests that he might…

Research integrity

I noticed, via a tweet from Judith Curry, that the House of Commons Science and Technology Committee is holding an inquiry into inquiry into Research Integrity. I also encountered this written evidence by Michael J Kelly, Emeritus Prince Philip Professor…
