Citizens often think of a state's interests in terms of the promotion of ideals such as democracy, a particular way of life, or other values which they endorse or see as part of their historical continuity and identity. In this domain as in others values are not fixed, and so a state's interests are dynamic and in a constant state of negotiation and construction.

The Paris climate conference in December, 2015 was a recognition that countries bring their climate policies to international meetings rather than create them during the negotiations (much less do they receive orders from the international community and then go home and implement them).

Climate change involves behaviors that are individually negligible, whose impacts go far beyond the spatial and temporal constraints that define our sense of community.

It is probably true that the economic benefits of being in the EU are a net positive to the UK, but a large number of people do not share in these benefits and the result is increasing inequality.

The very essence of civilized culture is that we deliberately institute, in advance of the happening of various contingencies and emergencies of life, devices for detecting their approach and registering their nature, for warding off what is unfavorable or at least for protecting ourselves from its full impact.

Climate change is not going to be prevented. It's not even going to be mitigated to the degree a rational person would want. As a result we're going to have to live with climate change and try to reduce the extent and rate of change as much as possible. This is not an inspiring or sexy project.

Climate change involves fundamental choices about how we want to live and what kind of world we want.
