Recent Articles

Planetary thinking

I was wanting to write a brief post about a recent Adam Frank article in the New York times called Earth Will Survive. We May Not. I also have a post about an earlier Adam Frank article, and I also…

low-probability, high-impact outcomes

Credit: Rowan T. Sutton (2018)There’s an interesting Earth System Dynamics Discussion paper presenting a a simple proposal to improve the contribution of IPCC WG1 to the assessment and communication of climate change risks. Essentially, one can estimate the risk of…

Airtime for policy experts

As I discussed in this post, there’s been a lengthy discussion on Twitter about climate scientists publicly discussing policy/solutions. In response to this, David Roberts tweeted the following: I think a) the over-reliance on climate scientists to do all the…

Science and Skepticism

oarobin posted a comment highlighting a video of a talk about Science and Skepticism by Steven Goodman. It essentially disusses the issue of reproducibility in science, and mentions some issues that I have myself. Ultimately, science is about unconvering “truth”.…

The #scicomm merry-go-round

Katharine Hayhoe has an article in Science about facts not being enough. It’s basically about how to effectively communicate to an audience that might have a tendency to reject the need to do something about climate change. As a result,…

Something about Tropical Cyclones

There’s an interesting Realclimate post discussing whether or not global warming makes tropical cyclones stronger. The basic answers is that we might expect the number of tropcical cyclones (TCs) to decrease overall, but see an increase in the frequency and…

Initial value problem vs boundary value problem

I haven’t actually looked at Judith Curry’s blog for a while, but popped across there and noticed a guest post about energy budgets, climate system domains, and internal variability. One reason why we think that we can actually do long-term…

The adults in the room

I was having another discussion on Twitter with Jean Goodwin, who posted the following quote. It’s attributed to Mark Largent and may have been delivered at a AAAS meeting. I’m interested in what other people think of this. I don’t…

Sea level rise

There’s a bizarre article in the Wall Street Journal by Fred Singer called, The Sea Is Rising, but Not Because of Climate Change. It’s actually so bonkers that it’s quite hard to know where to start. I’ll give it go,…

Dark webs

I’ve been trying to think of what to say about this New York Times articles discussing an alliance of heretics, and I’ve been struggling. I think it’s important to have people who challenge the orthodoxy, and who express views that…

RCP8.5

There’s been a lengthy discussion on Twitter about RCP8.5. I think it was initiated by Roger Pielke Jr, who continues in his campaign to police the scientific community: RCP 8.5 is by far the favorite in climate impact studies (graph).I…

It’s mostly about risk

I wanted to post this video (see end of post), that I first came across in this comment (H/T Pehr Björnbom). It’s a few years old, so some things may have changed, but it’s still mostly relevent. It’s a discussion…

Speaking out

There’s a current Twitter hashtag called #WeNeedToChangeTheWorld, which WMC has also discussed in this post. It’s bit cliché, but it’s probably true, for many reasons. As also mentioned in WMC’s post, Peter Jacobs tweeted the following The politics of the…

The Pursuit of Crappiness

Let’s take stock. Computers and codes are in shambles. The Law is broken. Schools are useless to most. Sports are dope. Most jobs are absurd. Administrations are plagued. We already are living in a boring dystopia. Yet here we are.…

Lewis and Curry, again

I should probably say something about the new Lewis & Curry paper. It’s mostly an update to their earlier paper that I’ve discussed before. Bottom line; there are reasons to be cautious. The basic formalism is that one can use…

20 years of hockey sticks

It’s almost 20 years since the publication of the first hockey stick paper (Mann, Bradley & Hughes 1998). In case people don’t know, the hockey stick refers to a temperature reconstruction that indicates that surface temperatures had been reasonably flat,…

The “truth” matters

There’s been a lengthy Twitter exchange about the Harvey et al. paper. In case you don’t remember, it was a paper essentially arguing that those blogs that tend to be dismissive of the risks associated with anthropogenic global warming (AGW)…

Five years

Turns out today is the fifth anniversary of me starting this blog. It’s been an interesting journey and I feel that I should reflect on what I’ve done, what I’ve learned, what I would have done differently, and what I’m…

Criticising the critics

I’ve recently come across a number of examples of people objecting to the manner in which some people engage in public criticism. There is a podcast with Sam Harris and Ezra Klein. It relates to a situation in which a…

Some impacts of warming by 1.5 and 2C

Something I’ve always struggled with when it comes to climate change is understanding the actual impacts of anthropogenic global warming. I think I understand the big picture quite well. If we continue to add greenhouse gases to the atmosphere, we…

An editorial response

Our response to Hermann Harde’s paper has finally appeared. What’s maybe more interesting is that there is also an editorial response by Martin Grosjean, Joel Guiot, and Zicheng Yu. It’s already been discussed at Realclimate and Rabett Run, but there…

The climate of the past

Richard Alley and Gavin Schmidt, currently two of the best climate communicators, recently gave presentations at the Smithsonian Institution, National Museum of Natural History, about how we study paleoclimate and how this understanding can help us to project what will…

The Paris climate targets

I’m currently in Oxford for a meeting and, having spent most of the train ride working on a book chapter I’m writing, I thought I would now spend some time writing a quick post about the recent Schurer et al.…

Flying

I noticed another discussion on Twitter about whether or not climate scientists should fly. I have written about this before and the issue of people making personal sacrifices is something I’ve pondered recently. I have a great deal of respect…

Moderation

I don’t particularly like discussing moderation and, in fact, it’s been much less of a problem than it once was. However, for various reasons, I thought I would quickly stress something about how, and why, I run this blog. I…

Ignoring adaptation?

Oren Cass has an article in the Wall Street Journal called Doomsday climate scenarios are a joke. It’s based on a report that he has written for the Manhattan Institute. The Manhattan Institute publishes a magazine called the City Journal…

Living in Liquid Worlds

I spent yesterday at a workshop – organised by Dominic Hinde – at the Institute for Advanced studies in the Humanities. The title of the workshop was Living in Liquid Worlds. The idea was to bring together scholars from different…

Talking solutions and motivating action

There’s been a lengthy Twitter discussion about scientists moving away from simply discussing the science of climate change, to talking about solutions and motivating action. I broadly agree with this; I do think that the main discussion should be about…
