Derailment risk: A systems analysis that identifies risks which could derail the sustainability transition
Abstract. The consequences of Earth system destabilisation will impact societies’ ability to tackle the causes of this problem. There are extensive agendas of study and action on the risks from the failure to realise rapid sustainability transitions to date (“physical risk”) and the risks resulting from these transitions going forward (“transition risk”). Yet there is no established agenda on the risk to sustainability transitions from both physical and transition risks and their knock on consequences. In response, we develop a conceptual socioecological systems model that explores how the escalating consequences of Earth system destabilisation impacts the ability of societies to undertake work on environmental action that re-stabilises natural systems. These consequences can act to spur processes of political, economic, and social change that could accelerate the growth in work done. Conversely, increasingly severe direct and indirect consequences could divert work and political support from environmental action, deepening Earth system destabilisation, thereby increasing the chance of passing a planetary threshold over which human agency to re-stabilise the natural world is severely impaired. We term this ‘derailment risk’: the risk that the path to re-stabilisation of the Earth system is derailed by interacting biophysical and socioeconomic factors. We use a case study of a climate tipping element – the collapse of the Atlantic Meridional Overturning Circulation (AMOC) – to illustrate this derailment risk. A range of policy responses can identify and mitigate derailment risk, including transformational adaptation. Acting on derailment risk is a critical requirement for deepening Earth system re-stabilisation and avoiding catastrophic outcomes.

Review of “Derailment risk: A systems analysis that identifies risks which could derail the sustainability transition” by Laybourn et al.
Recommendation: major revisions
This manuscript develops a conceptual socioecological model to illustrate derailment risk of a sustainability transition. This is an important topic in furthering our understanding of the complex interactions between the Earth system and human systems. The manuscript is well written. I have several remarks which should be addressed before the manuscript can be considered for publication.
1) I have problems with the term “destabilization”. For me this term implies that the Earth system becomes unstable, which in term implies either a hothouse runaway climate or much more variability.
You might just refer to a shift to another climate state (which might then be stable again). It might be best if the term is defined.
2) Lines 230-235: Here you mentioned that agricultural area might be lost in the future. Can you please provide references for this.
3) Line 235: “Such a collapse combined with climate change”. Isn’t the collapse due to climate change?
4) Line 239: What do you mean by work? Resources/funding/effort or actual labour work?
5) Line 264: “... in the round”. What do you mean by that expression?
6) Line 281: Can you make your model more quantitative? ESD aims to publish quantitative studies.
One way would be to make a systematic literature study based on studies of each link of your model.
Also links with a “?”: are previous studies inconclusive or are there no studies at all on those links?
How robust are the “+” and “-” links?

We thank the reviewer for their careful review and these positive comments. Below we respond to specific comments and propose responses and improvements that could be incorporated into a revised manuscript.
I have problems with the term “destabilization”. For me this term implies that the Earth system becomes unstable, which in term implies either a hothouse runaway climate or much more variability. You might just refer to a shift to another climate state (which might then be stable again). It might be best if the term is defined.
We appreciate that the term “destabilization” can imply, for example, trajectories toward a hypothesised hothouse runaway climate. This was not our intention. Instead, it was to highlight that it is not ‘just’ the climate system that is experiencing change but also other elements of the Earth system. We do, though, want to make some link to the potential for derailment risk, as we define it, to contribute toward a reduction in work which could increase the potential for a transition to a new, more dangerous state. We agree that we need to carefully specify our terminology here. The destabilisation we refer to is biophysical and socio-economic. Our central thesis is that interactions between biophysical and socio-economic systems can produce feedback loop dynamics that have reinforcing effects. Such effects could significantly degrade human societies’ ability to effectively respond to the challenges of climate and ecological change. We will improve how these is articulated.
Lines 230-235: Here you mentioned that agricultural area might be lost in the future. Can you please provide references for this.
The loss of agricultural area is explored in OECD, 2021, but has not been referenced, apologies. We will correct this.
Line 235: “Such a collapse combined with climate change”. Isn’t the collapse due to climate change?
The quote is taken from the OECD paper (OECD, 2021). It is in reference to modelling of an AMOC collapse that explores the effect of the collapse on agriculture at current levels of warming, and then at 2.5C of warming. The authors are comparing the two scenarios. We will make clear the use of this text in the revised manuscript.
Line 239: What do you mean by work? Resources/funding/effort or actual labour work?
Our concept of work in relation to derailment risk is intentionally broad, encompassing physical work, resource use, funding, all the way to less tangible factors, such as political support, which determines other forms of work. This is developed in section 2. We will carefully define “work” when it is first introduced.
Line 264: “... in the round”. What do you mean by that expression?
In this context, we meant “in the round” to mean that SSPs do not include a wider set of interactions between climate change and other areas of Earth system change, such as feedbacks between rising temperatures and biogeochemical flows, which present risks for societies and economic systems. These ‘missing’ interactions may be very important with regards emergent destabilising socio-ecological system feedback loops. We will carefully explain this in the revised manuscript.
Line 281: Can you make your model more quantitative? ESD aims to publish quantitative studies. One way would be to make a systematic literature study based on studies of each link of your model.
Also links with a “?”: are previous studies inconclusive or are there no studies at all on those links? How robust are the “+” and “-” links?
Our objective in this manuscript is to produce a qualitative model output that would be of value to policy makers and wider society. In this manuscript we first need to define the scope of the modelling activity and identify what we assess to be first-order terms and dynamics. In doing so we can establish the concept of ‘derailment risk’ and thus a qualitative model is the best initial step for doing so. In the revised manuscript we will provide more detailed supporting literature with regards the interactions and polarities of such interactions. We will also provide a discussion of more quantitative extensions to this concept and modelling.

The paper “Derailment risk: A systems analysis that identifies risks which would derail the sustainability transition” by Laurie Laybourn, Joseph Evans and James Dyke nicely illustrates the risk emerging to a sustainability rather than earlier works that elaborate on physical risks and transition risks. Methodologically, the paper develops a feedback diagram between Earth system destabilisation, Earth system impacts, political support and transition risks towards the ability to tackle the root causes of Earth system destabilisation. Overall, I think that the paper tackles an important issue whether societies are (and under which circumstances) able to work on environmental action. The authors apply their framework then on a climate tipping point, the Atlantic Meridional Overturning Circulation (AMOC). I think the paper is well written but should take into account the following comments before publication:
- The authors explain well in which contexts derailment risks are relevant in case of negative feedbacks between political instability to political support to work expended. However, I wonder whether a different case study than the AMOC might be easier to put into the context of the feedback diagram that the authors develop (e.g. deforestation of the Amazon rainforest?). If the authors decide to stick with the AMOC example (which I am happy to support), I would recommend:
- Can the authors set the current state of research on the AMOC-tipping better into context? so where do we stand with respect to a potential AMOC tipping (some helpful references might be:

- 242-245: While an AMOC shutdown indeed changes monsoon patterns, it decreases temperatures regionally, and partially also in regions where Xu et al., 2020, PNAS assess the largest risk of leaving the human climate niche (e.g. Sahel, Arabian Peninsula), see e.g. Jackson et al., 2015, Climate Dynamics. Therefore, I would conclude that AMOC impacts on the human climate niche are inconclusive to say the least. Therefore, I think that the argumentation in L. 242-245 should be sharpened.
- Please check references carefully. I couldn’t find the following references in the reference list: Arneth et al., 2019; Steffen et al., 2018; University of Exeter et al., 2023, …
- I like how the authors reason their feedback diagram in figure 1 and explain their links afterwards in the main text. However, I agree with the other reviewer that a systematic literature review would significantly strengthen the paper but at least a more thorough referencing in section 2 would be very helpful, I think.
- Optional: I like how the authors put their conceptual framework into context in the discussion and conclusion. I wondered if the authors have any idea how it could be possible to translate the feedback diagram into a dynamical system, e.g. using differential equations.

We are very grateful for these reference suggestions. We will review these and update the manuscript accordingly. We did consider some but thought this example was particularly clear in the risks presented by, for example, changes to agriculture and how these could lead to derailment risk. But we will set the research in a wider context, including using the references provided. Ditlevsen, P. and Ditlevsen, S., 2023 came out after our draft and our first thoughts were that it needed to be included!

We thank the reviewer for this clarification. We will carefully specify the impacts AMOC may have on social-economic systems.

However, I agree with the other reviewer that a systematic literature review would significantly strengthen the paper but at least a more thorough referencing in section 2 would be very helpful, I think.
We have taken on board this and the related comment from Reviewer 1 and will be including a much more systematic use of literature to substantiate the interactions we sketch out in our conceptual model.
Optional: I like how the authors put their conceptual framework into context in the discussion and conclusion. I wondered if the authors have any idea how it could be possible to translate the feedback diagram into a dynamical system, e.g. using differential equations.

A quantitative model using dynamical systems is very much within the scope of our aspirations for this work. Given the complexity of the biophysical and socio-economic systems it can be very challenging to produce useful formalism that captures the various interactions. We hope that this study can firmly establish the boundaries of such quantitative modelling exercises. We will make this and other possible future work clear in the Discussion section in the revised manuscript.
