Consider climate change, which raises the stakes of communication to the global level of the species and the planet. Unless humans conclude their deliberations about this question and translate the answers into timely political and personal actions, we may be done for prematurely. What is the present state of planet Earth, and what could be its future? The answer to the question of what ought to be, might appear self-evident: survival and sustainability for the planet and its peoples and species. But the capacity of scientists, politicians, and citizens to weigh the more specific answers with due diligence depends on the institutions, technologies, practices, and discourses of communication available to them. Communication is a necessary, if far from sufficient, condition for the production and dissemination of knowledge that may help people solve environmental and other practical problems in common. The record shows that, at least in such matters, the answer to the familiar question, ‘Can’t we just talk about it?’ is: No.
Analysis box 1.1 Climate and justice
Climate change – how to understand it, what to do about it – places communication in long perspectives of natural evolution and human history. Unlike just a couple of generations ago, it is now meaningful to communicate, and to disagree, about the natural environment as a public issue:
The assessment of climate change as a human and social problem that invites collective action depends on geological and meteorological evidence and, to a degree, written sources from historical time. Both kinds of information exist for the so-called Little Ice Age – a period of unusually cold weather around the middle of the last millennium. The dating of the Little Ice Age is subject to some disagreement; its earliest beginning is normally set around 1300, its end around 1850. The disagreements bear witness to conflicting interpretations of both natural evidence and cultural sources as well as to different theoretical conceptions of the relationship between climate change and human civilization – nature and culture. In addition to analyses of ice cores and tree rings, the empirical materials include documentation on the changing prices of grain, following good, bad, and disastrous harvest seasons. A classic contribution by the historian, Emmanuel Le Roy Ladurie (1972/1967), charted “the history of the climate since the year 1000” as a backdrop to the living conditions of ordinary people during the period; his study relied, among other things, on a detailed documentation of the dates of wine harvests. Another study, joining meteorology with art history, showed how, over the centuries, the Little Ice Age affected the color and style of nature paintings (Neuberger, 1970). And the hard times of several centuries gave rise to all manner of both practical and religious reflections, a small portion of which was put into writing by “country clergymen and gentleman scientists with time on their hands.” In 1316, one of these sources noted that the mass of rain “seemed as though it was THE FLOOD” (Fagan, 2000: xiii, 38).
the Little Ice Age Neither environmental determinism nor social determinism is tenable when it comes to recognized problems and potential solutions on the scale of global warming. The natural environment, as found and increasingly modified and made by human societies through tools and technologies, is intertwined with historical developments and social changes:
Perhaps most famously, a catastrophic wheat harvest in France in 1788, and the resulting shortage of grain and bread, was among the factors contributing to the revolution of 1789.
It is generally accepted that, at least since the nineteenth century, human activity has come to affect the natural environment in fundamental ways and with long-term consequences. In a contemporary perspecti...
