I think one would need that time machine to confidently say it was impossible. — unenlightened
As for global social collapse, as I asked earlier, how is it that China is supposed to collapse. — frank
China is held together by the tight grip of a dictatorship. It's already a touch and go operation which could unravel at any time. Add a big pile of stress on to the system, and China most likely unravels in to a collection of local warlord ruled sections. — Jake
1. Climate change is unstoppable.
2. Social collapse will be worldwide, and in the next 10 years or so.
3. This will involve Flooding caused by sea-level rises displacing huge populations, decline in crop yields leading to starvation even in developed countries, collapse of infra-structure, power, clean water particularly.
4. There's fuck all to be done to stop it.
5. So what might we do or think or discuss in the meantime? — unenlightened
Please talk about climate change with reference to the paper and the evidence within or elsewhere for its claims along with counterevidence, for those who disagree, from other scientific sources. Everything beyond that will be subject to deletion unless there's a very good reason for its inclusion. — Baden
The issue is not whether it's impossible. If the scientific community truly believed that human extinction is possible due to climate change in the next ten years, this would be of tremendous import. — frank
This paper is not the venue for a detailed examination of all the latest climate science. However, I reviewed the scientific literature from the past few years and where there was still large uncertainty then sought the latest data from research institutes. In this section I summarise the findings to establish the premise that it is time we consider the implications of it being too late to avert a global environmental catastrophe in the lifetimes of people alive today.

The warming of the Arctic reached wider public awareness as it has begun destabilizing winds in the higher atmosphere, specifically the jet stream and the northern polar vortex, leading to extreme movements of warmer air north in to the Arctic and cold air to the south. At one point in early 2018, temperature recordings from the Arctic were 20 degrees Celsius above the average for that date (Watts, 2018). The warming Arctic has led to dramatic loss in sea ice, the average September extent of which has been decreasing
at a rate of 13.2% per decade since 1980, so that over two thirds of the ice cover has gone (NSIDC/NASA, 2018). This data is made more concerning by changes in sea ice volume, which is an indicator of resilience of the ice sheet to future warming and storms. It was at the lowest it has ever been in 2017, continuing a consistent downward trend (Kahn, 2017).
Given a reduction in the reflection of the Sun’s rays from the surface of white ice, an ice-free Arctic is predicted to increase warming globally by a substantial degree. Writing in 2014, scientists calculated this change is already equivalent to 25% of the direct forcing of temperature increase from CO2 during the past 30 years (Pistone et al, 2014). That means we could remove a quarter of the cumulative CO2 emissions of the last three decades and it would already be outweighed by the loss of the reflective power of Arctic sea ice. One of the most eminent climate scientists in the world, Peter Wadhams, believes an ice-free Arctic will occur one summer in the next few years and that it will likely increase by 50% the warming caused by the CO2 produced by human activity (Wadhams, 2016).4 In itself, that renders the calculations of the IPCC redundant, along with the targets and proposals of the UNFCCC.
Between 2002 and 2016, Greenland shed approximately 280 gigatons of ice per year, and the island’s lower-elevation and coastal areas experienced up to 13.1 feet (4 meters) of ice mass loss (expressed in equivalent-water- height) over a 14-year period (NASA, 2018). Along with other melting of land ice, and the thermal expansion of water, this has contributed to a global mean sea level rise of about 3.2 mm/year, representing a total increase of over 80 mm, since 1993 (JPL/PO.DAAC, 2018). Stating a figure per year implies a linear increase, which is what has been assumed by IPCC and others in making their predictions. However, recent data shows that the upward trend is non-linear (Malmquist, 2018). That means sea level is rising due to non-linear increases in the melting of land-based ice.
The observed phenomena, of actual temperatures and sea levels, are greater than what the climate models over the past decades were predicting for our current time. They are consistent with non-linear changes in our environment that then trigger uncontrollable impacts on human habitat and agriculture, with subsequent complex impacts on social, economic and political systems.
I've stumbled into this with in economic and financial debate, the phenomenon of the existence of the so-called permabears. Now a permabear forecasts the imminent collapse of the stock market and the financial system. He or she sounds like a breath of fresh air to the very annoying permabull-people trying to sell you stocks and who see everything through rose-coloured glasses. At least at first. For one year or two. Now some of the arguments are indeed correct and can be very convincing. About every 10-25 years that is. We do have a financial crisis every now and then.Yawn...
Yes, much has been written on this subject: https://en.wikipedia.org/wiki/Doomsday_cult
Here's a fairly comprehensive list of predicted apocalyptic events, many made by science:

For a walk down memory lane, here are some scientific doomsday predictions made at the time of the first Earh Day in 1970:

The more interesting phenomenon is how the adherents react when the prophecy fails and how they attempt to maintain their beliefs in light of them being proven wrong. Yours is particularly troubling for adherents because the date is only 10 years (or so) away. Can we declare the paper wrong in 15 years? — Hanover
Thanks for the factless reference-less patronising condescension. Sea-levels may fall as well as rise, terms and conditions apply. — unenlightened
What do you want me to back up? — frank
Don't tell me what I know, you £$%^*. I'll tell you what I know, which is that the past and the present are the only things anyone whatsoever of whatever repufuckingtation has from which to extrapolate anything at all about the future.
And where is that reference? Or are you unwisely extrapolating from text books you've seen on other topics? — unenlightened
I'm not sure why you're fixated on my textbook. — frank
My turn to patronise. Yes dear, that's right, clever scientists collect a lot of data about the past and from that they produce a model or algorithm that dynamically matches the data sets (to an approximation). And then they use the same model and the current data set to extrapolate to the future. And always the data sets are partial, the models are partial and the predictions are tentative. And this means that a scientist can be reputable, and not stupid, and still get their predictions wrong. So there's no need to slag them off when you disagree with them, or compare them with astrologers and conspiracy theorists.They computer simulate. — frank

Have professionals in the sustainability field discussed the possibility that it is too late to avert an environmental catastrophe and the implications for their work? A quick literature review revealed that my fellow professionals have not been publishing work that explores, or starts from, that perspective. That led to a third question, on why sustainability professionals are not exploring this fundamentally important issue to our whole field as well as our personal lives. To explore that, I drew on psychological analyses, conversations with colleagues, reviews of debates amongst environmentalists in social media and selfreflection on my own reticence. Concluding that there is a need to promote discussion about the implications of a social collapse triggered by an environmental catastrophe...
I asked my fourth question on what are the ways that people are talking about collapse on social media. I identified a variety of conceptualisations and from that asked myself what could provide a map for people to navigate this extremely difficult issue. For that, I drew on a range of reading and experiences over my 25 years in the sustainability field to outline an agenda for what I have termed “deep adaptation” to climate change.
Instead, this article may contribute to future work on sustainable management and policy as much by subtraction as by addition. By that I mean the implication is for you to take a time to step back, to consider "what if" the analysis in these pages is true, to allow yourself to grieve, and to overcome enough of the typical fears we all have, to find meaning in new ways of being and acting.. That may be in the fields of academia or management - or could be in some other field that this realisation leads you to.
It is a truism that we do not know what the future will be. But we can see
trends. We do not know if the power of human ingenuity will help sufficiently to change the environmental trajectory we are on. Unfortunately, the recent years of innovation, investment and patenting indicate how human ingenuity has increasingly been channelled into consumerism and financial engineering. We might pray for time. But the evidence before us suggests that we are set for disruptive and uncontrollable levels of climate change, bringing starvation, destruction, migration, disease and war.
We do not know for certain how disruptive the impacts of climate change will be or where will be most affected, especially as economic and social systems will respond in complex ways. But the evidence is mounting that the impacts will be catastrophic to our livelihoods and the societies that we live within. Our norms of behaviour, that we call our “civilisation,” may also degrade. When we contemplate this possibility, it can seem abstract. The words I ended the previous paragraph with may seem, subconsciously at least, to be describing a situation to feel sorry about as we witness scenes on TV or online. But when I say starvation, destruction, migration, disease and war, I mean in your own life. With the power down, soon you wouldn’t have water coming out of your tap. You will depend on your neighbours for food and some warmth. You will become malnourished. You won’t know whether to stay or go. You will fear being violently killed before starving to death.
These descriptions may seem overly dramatic. Some readers might consider them an unacademic form of writing. Which would be an interesting comment on why we even write at all. I chose the words above as an attempt to cut through the sense that this topic is purely theoretical.
The World Bank reported in 2018 that countries needed to prepare for over 100 million internally displaced people due to the effects of climate change (Rigaud et al, 2018), in addition to millions of international refugees.
The observed phenomena, of actual temperatures and sea levels, are greater than what the climate models over the past decades were predicting for our current time. They are consistent with non-linear changes in our environment that then trigger uncontrollable impacts on human habitat and agriculture, with subsequent complex impacts on social, economic and political systems. I will return to the implications of these trends after listing some more of the impacts that are already being reported as occurring today....
The impacts I just summarised are already upon us and even without increasing their severity they will nevertheless increase their impacts on our ecosystems, soils, seas and our societies over time. It is difficult to predict future impacts. But it is more difficult not to predict them. Because the reported impacts today are at the very worst end of predictions being made in the early 1990s - back when I first studied climate change and modelbased climate predictions as an undergraduate at Cambridge University.
Given the climate science we discussed earlier, some people may think this (current) action is too little too late. Yet, if such action reduces some harm temporarily, that will help people, just like you and me, and therefore such action should not be disregarded. Nevertheless, we can look more critically at how people and organisations are framing the situation and the limitations that such a framing may impose. The initiatives are typically described as promoting “resilience”, rather than sustainability. Some definitions of resilience within the environmental sector are surprisingly upbeat. For instance, the Stockholm Resilience Centre (2015) explains that “resilience is the capacity of a system, be it an individual, a forest, a city or an economy, to deal with change and continue to develop. It is about how humans and nature can use shocks and disturbances like a financial crisis or climate change to spur renewal and innovative thinking.” In offering that definition, they are drawing on concepts in biology, where ecosystems are observed to overcome disturbances and increase their complexity (Brand and Jax, 2007).
