Greater future global warming?

Before I go out I wanted to briefly mention a recent paper by Patrick Brown and Ken Caldeira called [g]reater future global warming inferred from Earth’s recent energy budget. Patrick Brown already has a nice blog post about this with…

Polar Bears and Arctic sea ice

Jeff Harvey, who is an occasional commenter here, is lead author of a recent paper on [i]nternet blogs, polar bears, and climate-change denial by proxy. The paper itself is open access, and if you would like to read some posts…

Science communication – again

There are a number of possible things to write about, but I thought I might have a brief rant about a topic I find of interest. A tweet by David Roberts (who I mostly like) caused a bit of a…

Going Nuclear

An epic tweetspat with pseudo-modern engineers made me think of the following confutation of the Breakthrough playbook: First, nuclear energy needs to compete with fossil fuels, not renewables like wind or solar. This point rests on the basic observation that …

Combining different ECS estimates

I wanted to briefly highlight a new paper by Nic Lewis and Peter Grünwald called [o]bjectively combining AR5 instrumental period and paleoclimate climate sensitivity evidence. You may want, however, to be cautious of the term objective. As the title indicates,…

Carbon budget constraints

I’d been meaning to highlight a statement from Kevin Anderson for quite some time. A brief lull in postings gives me a chance to do so. It relates to the Paris goal of keeping global warming below 2oC. I haven’t…

Climate communicators in Edinburgh

It was a bit of a weekend of climate communication in Edinburgh. Yesterday morning I went along to Dynamic Earth, where the Natural Environment Research Council was hosting an event called UnEarthed. Ed Hawkins was there with a display about…

Mertonian norms

There are a set of norms of science, first presented by Robert K Merton and known as the Mertonian norms. I found what seems to be a good description of them here. There are four Mertonian norms, called universalism, communalism,…

A real time global warming index

This is a guest post by Karsten Haustein, a researcher in the School of Geography and the Environment at the University of Oxford. The post is about a new paper that discusses their real time global warming index. Have you…

I’m confused….

Recently, Warren Pearce and colleagues published a paper called [b]eyond climate consensus which I wrote about here. There was a response from John Cook, one from Naomi Oreskes, and a Guardian article by multiple authors. So, why am I confused?…

If it’s a fight?

I’ve had very little to say recently, and still don’t have much to say. However, just to keep things ticking over, I thought I would highlight this David Roberts article called [c]onservatives probably can’t be persuaded on climate change. So…

Jordan Peterson speaks the truth

I may, justifiably, be accused of this post having a clickbait title. What it refers to, though, is a youtube debate between Philip Moriarty (a Physics Professor at the University of Nottingham) and Fred McVittie (whose credentials I, unfortunately, do…

Carbon Dioxide Removal

There’s a bit of a debate going on a about economics and ethics, mostly on MT’s blog, but also on Stoat, and a little bit here. I have to be honest, I’m not entirely sure what people are actually disagreeing…

Civility

A recent discussion has led me to think a bit more about civility. This was partly motivated by my own intention to maintain it when I started this blog (which didn’t always succeed) and by the other party being someone…

Sound Science

By some serendipity, I noticed and responded to a tweet where Kevin Folta was trying to ridicule the accusation that he was “pro-GMO”: How about "pro-artificial plant-growth environments" or simply "pro-biotech"? Self-serving caricatures won't make social labeling disappear. — willard…

Bruno Latour

I came across an interesting Bruno Latour, a sociologist, with an interest in Science and Techology Studies (STS), who was involved with what has been called the “science wars”. I actually found much of what he said in the interview…

Economics and Values

Michael Tobis has a post in which he argues that what we are doing to the climate will persist for many generations and, consequently, that it is immoral to continue what were’e doing and that we should address this as…

The Virial Theorem

I had another brief Twitter discussion with Ned Nikolov, whose paper I discussed in this post. Ned seems to think that there is no atmospheric greenhouse effect and that the enhanced surface temperature is due to atmospheric pressure somehow enhancing…

A bit more about clouds

A few years ago I posted a video by Andrew Dessler that was discussing whether or not Equilibrium Climate Sensitivity could be less than 3oC. The bottom line was that the best estimate for ECS is about 3oC. Given that…

Chatham Air Raid

For the 100th anniversay of the start of World War I, I wrote a post about an ancester of mine, Kenneth Smith, who died on 1 January 1919, when Her Majesty’s Yacht Iolaire sank after hitting rocks in the mouth…

A Harde response

Earlier this year, I wrote a post about a paper by Hermann Harde that argued that most of the rise in atmospheric CO2 was natural. If you want more details of why this suggestion is nonsense, you can read my…

A bit more about committed warming

On a number of occasions I’ve pointed out that our warming committment is not actually the equilibrium temperature to our current atmospheric concentration because, if we halted all emissions, atmospheric CO2 would drop as the natural sinks took up more…

A bit more about carbon budgets

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.…

Climateball, GWPF style

I came across a Global Warming Policy Forum (GWPF) post called climate scientists shoot the messenger. That it’s from the Forum, rather than the Foundation, may be relevant. It discusses the recent Millar et al. paper (that I discussed here…

Assessing global warming

A couple of years ago I wrote a joint post with Roger Pielke Sr that discussed assessing anthropogenic global warming. The post basically used changes in ocean heat content to assess anthropogenic global warming. The basic idea (which is not…

Own goal

I thought I might comment a bit further on the recent Millar et al. paper, [e]mission budgets and pathways consistent with limiting warming to 1.5 °C, that I discussed in this post. I’ve found the whole public dialogue about this…

Andy Skuce

As many probably already know, Andy Skuce passed away last week. Andy was someone I greatly respected who made a significant, positive contribution to the dialogue about climate and energy. Andy was a key contributor to Skeptical Science, and wrote…

More time …. really?

A recent paper about [e]mission budgets and pathways consistent with limiting warming to 1.5 °C essentially argues that it is still possible to follow an emission pathway that will give us a good chance of keeping warming below 1.5oC. More…
