Nature and Culture 2012 special issue: Climate Change as Post Normal Science

Werner Krauss, Mike S. Schäfer and Hans von Storch: Introduction: Post-Normal Climate Science

Jerome Ravetz: The Significance of the Hamburg Workshop: Post-Normal Science and the Maturing of Science
Abstract: In this essay I review my own involvement in climate science, and attempt to draw some useful lessons. I start with a critique of the theory of post-normal science (PNS). This is derived from the experience of the effective criticisms of PNS that were made on the blogosphere. I proceed to a critique of climate science itself, which might be described as the attempt to solve a post-normal problem by "normal science" methods. Since quality, in a variety of aspects, became crucial in the Climategate debates, I analyze that concept in the fraught context of a politicized, contested science. Such sciences have the seeds of tragedy for those who innocently engage with them believing that their task is simply to speak truth to power. Finally, out of my personal history I suggest that we keep in mind the personal investment of anyone holding a contested view, and respect their struggles to maintain integrity when their core beliefs are under attack. This motivates the fostering of non-violence in debates on policy science issues.

Silke Beck: Between Tribalism and Trust: The IPCC Under the "Public Microscope"
Abstract: This article explores how the Intergovernmental Panel on Climate Change (IPCC) has dealt with growing public scrutiny of its workings. It reviews recent initiatives set up to respond to the Climategate controversy. An independent review of the IPCC undertaken by an international scientific umbrella body—InterAcademy Council—can be shown to have triggered one of the turning points in the debate, placing the focus of attention on the IPCC's transparency and accountability. However, the council's recommendations have been implemented by the IPCC in such a way that the issue of public trust is treated as one of effective communication. The article then explains how IPCC's responses to Climategate can be traced back to the linear model of expertise. The article concludes with a discussion why the challenge of producing policy-relevant knowledge under conditions of heightened public scrutiny also requires new forms of scientific appraisal aimed at wider publics.

Jeroen P. van der Sluijs:Uncertainty and Dissent in Climate Risk Assessment: A Post-Normal Perspective
Abstract: Uncertainty complexity and dissent make climate change hard to tackle with normal scientific procedures. In a post-normal perspective the normal science task of "getting the facts right" is still regarded as necessary but no longer as fully feasible nor as sufficient to interface science and policy. It needs to be complemented with a task of exploring the relevance of deep uncertainty and ignorance that limit our ability to establish objective, reliable, and valid facts. This article explores the implications of this notion for the climate science policy interface. According to its political configuration the Intergovernmental Panel on Climate Change (IPCC) adopted a "speaking consensus to power" approach that sees uncertainty and dissent as a problematic lack of unequivocalness (multiple contradictory truths that need to be mediated into a consensus). This approach can be distinguished from two other interface strategies: the "speaking truth to power approach," seeing uncertainties as a temporary lack of perfection in the knowledge (truth with error bars) and the "working deliberatively within imperfections" approach, accepting uncertainty and scientific dissent as facts of life (irreducible ignorance) of which the policy relevance needs be explored explicitly. The article recommends more openness for dissent and explicit reflection on ignorance in IPCC process and reporting.

Roger A. Pielke: Post-Normal Science in a German Landscape
Abstract: This essay explores the management and creation of ignorance via an exploration of the landscape of eastern Germany, which has seen profound social, political, and technological changes over the past several decades. Like in many places around the world decision makers in eastern Germany are seeking to reach a future state where seemingly conflicting outcomes related to the economy and the environment are simultaneously realized. The management of ignorance is an important but often overlooked consideration in decision making that the concept of "post-normal science" places into our focus of attention.

Werner Krauss and Hans von Storch: Post-Normal Practices Between Regional Climate Services and Local Knowledge
Abstract: Recent surveys show that the communication about climate change between science and the public is severely disturbed. In this article we discuss this problem in focusing on both regional climate services and other, local forms of knowledge. The authors suggest that climate science and its public services have to critically revise their own practices and to acknowledge other forms of knowledge about climate as constitutive. Based on approaches from geography and anthropology, the article first discusses the short history and "normal practices" of regional climate services and how they approach the public. Outlining the potentials and constraints of this concept, the article focuses on the friction, on "its openness to change as it rubs up against society" (Hulme 2007). The focus then shifts to local knowledge systems and how they deal with the challenges of a changing climate. In addition to the "extended peer review" as a new option for climate research in a post-normal setup, the authors discuss the possibility of an "extended knowledge basis," that is, the integration of different forms of climate knowledge with a special focus on regional populations.
