The truly shocking information on the trends in climate change and its impacts on ecology and society are leading some to call for us to experiment with geoengineering the climate, from fertilizing the oceans so they photosynthesize more CO2, to releasing chemicals in the upper
atmosphere so the Sun’s rays are reflected. The unpredictability of geoengineering the climate through the latter method, in particular the dangers of disturbances to seasonal rains that billions of people rely on, make it unlikely to be used (Keller et al, 2014). The potential natural geoengineering from increased sulphur releases from volcanoes due to isostatic rebound as weight on the Earth’s crust is redistributed is not likely to make a significant contribution to earth temperatures for decades or centuries.
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. As we are considering here a situation where the publishers of this journal would no longer exist, the electricity to read its outputs won’t exist, and a profession to educate won’t exist, I think it time we break some of the conventions of this format. However, some of us may take pride in upholding the norms of the current society, even amidst collapse. Even though some of us might believe in the importance of maintaining norms of behaviour, as indicators of shared values, others will consider that the probability of collapse means that effort at reforming our current system is no longer the pragmatic choice. My conclusion to this situation has been that we need to expand our work on “sustainability” to consider how communities, countries and humanity can adapt to the coming troubles. I have dubbed this the “Deep Adaptation Agenda,” to contrast it with the limited scope of current climate adaptation activities. My experience is that a lot of people are resistant to the conclusions I have just shared. So before explaining the implications, let us consider some of the emotional and psychological responses to the information I have just summarised.
