If Copenhagen was the last chance to stop climate chaos, if we had to turn the whole ship round by 2012 to stand a chance but are now racing even faster for the rocks, if the expert commentators think we are heading for at least 650ppm CO2 in the atmosphere, and a rise of 4C that will make most if not all the world uninhabitable for humans, then where do we find the time from to stop it?

To put it simply: We are not too late to stop the devastating impacts of climate change, because we are not too late to stop the economic-industrial complex from pumping out carbon emissions.

These emissions have raised overall global temperatures 0.8C since pre-industrial times, and our industrial activity over the last 30 years means we have another 0.6C temperature rise in the pipeline. This means we are committed to a rise of 1.4C.

If the scientists are right, then rapidly reducing and halting emissions – and then reversing the process through enabling the soils, the oceans and the forests to regenerate – means we are only committed to climate chaos to the extent that we are committed to this economic-industrial system.

We can only de-couple our everyday activities from this system if we propose and enact an alternative, and if we can succeed in enacting it in the face of all the forces that would stop it taking place.

It doesn’t have to happen everywhere all at once, but it has to happen, and it has to be able to spread like wildfire through people, communities and countries being inspired to take it up, and through their refusing to back down in the face of the forces that would stop it. Such change happens regularly throughout the world and throughout history – it depends entirely on individuals and networks and communities and peoples saying ‘enough, and no more’.

One of the strongest ways of stopping people from pursuing an alternative to what has become an ecocidal system, is to persuade us that there is no alternative, that human nature is such that any such change is unrealistic, that there is no evidence that it is possible, that change itself is not possible.

Yet, quite clearly change is fundamental to being human. Our creativity and malleability is evident across thousands of different societies and histories. And furthermore what is clear – looking across the historical and contemporary record – is that our current dominant arrangement (in which an economic-industrial ‘boom and bust’ Market is imposed by the State) is the exception rather than the rule.

When we fail to be persuaded that this is how it has to be, that there is no other way of being human, then the argument with which we are countered is that any other way is far inferior, that no other way can meet our needs, can feed the world.

Yet this way of feeding the world – destroying the topsoil, draining the soil of its fertility, emptying the ocean of life – destroys the basis of human life and only feeds some and not others. There is plenty to go round, but in a system driven by scarcity and greed, many starve. There is plenty of land to grow what we need in a system shaped by concern for the well-being of each other, ecosystems and other species.

To be realistic is to be completely pessimistic about our chances of survival if we think we can only put our faith in what has become an ecocidal economic and political system. To be realistic is to be optimistic if we put our faith in each other.

This is the first in a series of ‘Case for the Commons: The kinder Society we want’ posts – the second will argue that international agreements have failed and will fail: what is needed is a ‘Commons’ approach to the climate and related crises.
