Hi Brian,thanks for point out this talk (and connecting it back to the introductory book "Earth System Science", which I agree is great).
Applying 'systems thinking' around 'tipping points' to social dynamics raises very interesting issues about how radical change comes about.
The classic revolutionary/anti-capitalist perspective maintains that we need to change the fundamentals of the system in order to bring about radically different dynamic. Following the model of the great modern (American, French, Russian, Chinese, Cuban etc) revolutions, systemic change comes first, from which then new social dynamic emerge. This is an appealing model, because it sounds like you know what you do, but also a paralyzing one, because you need to the big things first, before the small things can be done.
The tipping point view would maintain that we can move towards tipping points within the existing dynamics in order to bring about radically different ones once the threshold has been passed. This is, in a way, a scary model, because tipping points are, almost by definition, unpredictable, because of the many interacting cascades they can set of. Given that some of these cascades can provide negative feedback, meaning dampening change, it's also hard to predict where exactly the tipping points lies and what exactly will be tipped. On the other hand, it's an appealing vision, because it suggest that even smaller changes, if applied strategically, can result in large-scale transformations.
Lenton makes a decent point about the tipping points towards renewable energies that might be passed soon. On the technical side, we might have passed it, all the necessary elements are here already [1]. I think the fossil fuel sector knows this hence it's lobbying hard to delay that point has long as possible. The question is, is that enough of a tipping point, or will it simply displace the resource hungry growth imperative of capitalism?
The tension between these two points of view is visible in a fascinating recent discussion "How to Save the Planet: Degrowth vs Green Growth?" [2]. While they never mention the contrast between revolution and tipping points, it's clearly operative. Green Growth argues for using the existing system dynamics to affect its direction (de-carbonization), where as de-growth see as an approach that has not worked out in the last 30 years and connects it to the capitalism need for growth.
On an analytic level, I lean towards the latter, on a level of political strategy, towards the former. But that's a rather in-congruent position, I'm afraid.

Among the small but highly influential group of scientists building on the Gaia theory of Lovelock and Margulis, Tim Lenton might have been the most unobtrusive - until now. At 49 he's quite young for the impressive quantity and quality of the work he has produced. For instance, he's the author of a very short but fundamental book on biogeochemical cycles, tracing the vast and intricate process whereby specific elements such as carbon circulate through the atmosphere, the oceans and the earth's crust - with important detours through living beings (1). He was also the lead author, with Rockstrom, Schellnhuber and others, of the inaugural 2008 paper on tipping elements capable of provoking phase changes in the earth system (2). You could further check out a recent article in The Anthropocene Review, co-authored with Bruno Latour, on the role of Life in the production and maintenance of habitable conditions on our planet (3). Lenton appears for Zoom talks in a spare, book-lined bedroom, as though he forgot he's no longer a graduate student and didn't notice whatever cascade of honors has ensued since then. He's concerned with other cascades.Last summer Lenton was a co-author of a paper entitled "Climate Endgame: Exploring catastrophic climate change scenarios," which examines the existential risk to humanity posed by runaway global warming (4). The key concept is that of so-called "tipping cascades," which are likely to begin in earnest at only 1.5 degrees centigrade of global warming (we're currently around 1.2 degrees). In such cascades, one fundamental change in earth system dynamics sets off another, leading to consequences far beyond those outlined in the increasingly dire IPCC reports. The main difference between the IPCC consensus and Lenton's view concerns the rates of possible change, which are essentially linear for the former (more CO2, more warming), while for the latter, they necessarily pass accelerative thresholds affecting not only temperature, but also, the intricate dynamics of biogeochemical cycles.A couple weeks ago I started watching a talk that Lenton gave a year ago to a group - or really, a movement - called Scientist Rebellion. It's got the most ungainly title: "Positive tipping points to avoid climate tipping points" (5). After recapping the various cascade scenarios of the current climate emergency, he goes on to discuss reinforcing feedbacks that could push global society out of the current business-as-usual trajectory. Basically he's talking about cheap power from renewables and rising sales of electric cars as the drivers for major transformations in the sectors of battery storage, hydrogen fuel-cell production and "green fertiliser" (nitrogen produced without the use of methane feedstocks). The video is extraordinary because of the intense questions asked by the rebellious young scientists, including how does he deal emotionally with his own knowledge and whether it would be important to examine negative social tipping cascades, like the effects of European colonization of the Americas.I returned to the video last night, and finished watching it in parallel with my partner Claire. At some point near the end Lenton begins talking about coalitions between scientists, civil society, the financial sector and the media - in short, a concerted intervention in global political ecology, although he doesn't use the term. It was obvious that this was not a traditional egghead paper but an activist blueprint for global system change. According to Lenton it represents a possibly feasible pathway - a "fifty-fifty chance" - for avoiding the above-mentioned existential risk to the human species (and presumably, many many others).As soon as she had finished the video, Claire began googling around and found an article in the Guardian, only hours old, about a proposal that had just been pitched to the World Economic Forum in Davos, Switzerland. It's an operationalized plan produced by the Systemiq consultancy in collaboration with the Global Systems Institute directed by Lenton at the University of Exeter, under the title "The Breakthrough Effect: How to Trigger a Cascade of Tipping Effects to Accelerate the Net-Zero Transition" (6). This is not about a revolution, and concerning the Scientist Rebellion question about negative social tipping cascades, it's clear Lenton does not want to go there. This is about a consensual transformation of the material basis underpinning the current form of the corporate state, whose representatives gather every year at this time, on top of a Swiss mountain.Do you think it can be done? Will Davos Man finally answer the ecological question? Will you sign on too? Can a nudge in time save nine degrees of global warming?Or maybe the initial prophecy holds... cheers, Brian ***1.
