International Scholars Warning on Societal Disruption and Collapse

If you are a scientist or scholar you can still sign the letter before the end of 2020, and a final list will be published in January. 

A public letter signed by over 250 scientists and scholars from 30 countries, calls on policy makers to engage more with the growing risk of societal disruption and collapse due to damage to the climate and environment. The letter invites focus on how to slow, prepare for, and help those already suffering from, such disruptions. The signatories are specialists in a range of subject areas that relate to this challenge, who commonly believe it is time to listen to all the scholarship on humanity’s predicament.

The referenced letter and a full list of signatories, at the moment of publication on Dec 6th 2020, follows below. In English, an edited version of the letter appears in The Guardian (Monday 7th 2020). The letter will also be published in French.

Subject: Only if we discuss collapse might we prepare

As scientists and scholars from around the world, we call on policymakers to engage openly with the risk of disruption and even collapse of our societies. After five years of failing to reduce carbon emissions in line with the Paris Climate Accord (1), we must now face the consequences. 

While bold and fair efforts to cut emissions and naturally drawdown carbon are essential, researchers in many areas now consider societal collapse to be a credible scenario this century (2a & 2b). A range of views exist on the location, extent, timing, permanence and cause of such disruptions; but the way modern societies exploit people and nature is a common concern (3a & 3b).

Only if policymakers begin to discuss this threat of societal collapse might communities and nations begin to prepare and so reduce its likelihood, speed, severity, harm to the most vulnerable, and to nature. 

Some armed services already see collapse as an important scenario, requiring planning (4a and 4b). Surveys show many people now anticipate societal collapse (5). Sadly that is already the experience or memory of many communities in the Global South (6). However, the topic is not well reported in the media, and mostly absent from civil society and politics.

When potential collapse is covered by the media, it typically cites people who condemn discussion of the topic. Ill-informed speculations, such as on foreign misinformation campaigns, or impacts on mental health and motivation, will not support serious discussion (7). Rather, such claims risk betraying the thousands of activists and community leaders whose anticipation of collapse is part of their motivation to push for change on climate, ecology, and social justice. 

People who care about environmental and humanitarian issues should not be discouraged from discussing the risks of societal disruption or collapse. That could risk agendas being driven by people with less commitment to such values.

Some of us believe that a transition to a new form of society may be possible. That will involve bold action to reduce damage to the climate, nature and other people, including preparations for major disruptions to everyday life. We are united in regarding efforts to suppress discussion of collapse as hindering the possibility of that transition. 

We have experienced how emotionally challenging it is to recognise the damage being done, along with the growing threat to our own way of life. We also know the great sense of fellowship that can arise (8). It is time to invite each other into difficult conversations, so we can reduce our complicity in the harm, and be creative to make the best of a turbulent future (9).

Professor Jem Bendell of the University of Cumbria is one of the signatories. He explains:

“Over 250 scientists and scholars have issued a warning to humanity that we need to make the increasing disruption from climate change a focus of research and policy. We come from dozens of countries and subject disciplines and perceive a resistance by the establishment to serious engagement in adapting to the increasing disruptions to food, water, health, and the economy. It is time to listen to the scholarship and try to reduce harm from societal disruption and even collapse. I believe the growing movement for Deep Adaptation to societal breakdown can be part of that agenda.”

Total number of caveats upon signing:

Dr Wanchat Theeranaew: Our civilization is much more fragile than we believe. We are now entering the change of Earth System toward a new equilibrium. This alone will be extremely harmful to our civilization since all of our infrastructures were constructed based on stability.

Dr Wolfgang Knorr: This is not a statement of preference for any particular viewpoint within the broad debate of the Climate and Ecological Emergency, but rather an expression of a wish to broaden the debate as far as possible.

Dr Gwen Fischer: Climate disruption is happening and people's lives are unraveling.

Dr Mark Charlesworth: Having made clear that societal collapse cannot be dismissed in Charlesworth M and Okereke, C (2010) Policy responses to rapid climate change: An epistemological critique of dominant approaches, Global Environmental Change, 20(1), 121-129 

Dr Phoebe Barnard: We can be prepared, or caught unawares.  Discussion and preparedness for a full range of possibilities is essential, especially where partial (or even temporary) societal collapse will widen existing inequalities.

Professor Ira Allen: Failure to consciously negotiate what is, in effect, already a staggered collapse of the various systems that support humans' current forms of life will allow those most concerned with profiting off of this ruination to succeed, further immiserating the many.

Professor John Adams: We can no longer afford to govern through cognitive dissonance.
