The passages show that foundational questions like "What makes a system complex?" directly shape methodological approaches to climate models by establishing the conceptual framework for understanding the system being modeled. Specifically, the passages explain that foundational questions about complexity are addressed in Chapters One through Three, which develop a definition of "dynamical complexity" that bridges mathematical complexity theory and the physical systems studied by science [2][5]. This definition then informs the methodological questions taken up in Chapter Four, where a simple climate model is constructed from first principles and its limitations are considered [3]. The recognition that climate science is a "paradigmatic complex-systems science" is presented as essential for bringing all resources to bear on climate problems [3].
The passages further indicate that methodological questions—including how climate models are constructed, on what basis we trust them, and how to improve them—are directly informed by this foundational understanding of complexity [5]. The diversity of climate model families is noted as greater than in other sciences, and complexity theory…

From the book
disciplinary and holistic methods of climatology can help us better understand the nature of complex systems in general. Questions surrounding climate science can be divided into three rough categories: foundational, methodological, and evaluative questions. ”How do we know that we can trust science?" is a paradigmatic foundational question (and a surprisingly difficult one to answer). Because the global climate is so complex, questions like “what makes a system complex?” also fall into this category. There are a number of existing definitions of ‘complexity,’ and while all of them capture…
t we can trust science?" is a paradigmatic foundational question (and a surprisingly difficult one to answer, at that ). Chapters One, Two, and Three of this work will focus on foundational questions. Specifically, Chapter One outlines a novel approach to philosophy of science based on recent advances in information theory, and lays the groundwork for applying that approach to the problem of climate science. Chapters Two and Three review some contemporary work being done in complexity theory, with a particular focus on attempts to define and quantify the notion of “complexity” itself, then…
ystems that seem intuitively "simple" (e.g. a free photon in a vacuum) and systems that seem intuitively "complex" (e.g. the global climate) more clearly, and to begin to get a grasp on important differences between the methods of sciences that study systems with high dynamical complexity and those of sciences that study systems with low dynamical complexity. I then argue that, based on this definition, climate science is a paradigmatic complex-systems science, and that recognition of this fact is essential if we're to bring all our resources to bear on solving the problems posed by climate…
This quiet conceptual revolution has proceeded more-or-less independently in these disciplines until fairly recently. Increasingly, though, the question of whether there might be general principles underlying these cases—principles that deal with how systems of many highly connected interactive parts behave, regardless of the nature of those parts—has started to surface in these discussions. This is precisely the question that complexity theory aims to explore: what are the general features of systems for which the decompositionist approach fails to capture the whole story? What rigorous…
formation-theoretic objects (signals, for instance) rather than the physical and social systems studied by scientists. Dynamical complexity, a concept articulated in detail in the first third of the dissertation, is designed to bridge the gap between the mathematics of contemporary complexity theory (in particular the formalism of “effective complexity” developed by Gell-Mann and Lloyd [2003]) and a more general account of the structure of science generally. Dynamical complexity provides a physical interpretation of the formal tools of mathematical complexity theory, and thus can be used as…
More questions about this book
- Explain how "dynamical complexity" specifically addresses the limitations of existing complexity definitions developed for "information-theoretic objects," using the global climate as a primary example.
- If "dynamical complexity" provides a "physical interpretation of the formal tools of mathematical complexity theory," what specific insights might this offer for understanding fundamental concepts like "theories, explanation, and lawhood" within the philosophy of science?
- Considering climatology as a "paradigmatic complex systems science," how does the "interaction of many different components operating at many different temporal and spatial scales" necessitate a multidisciplinary approach, and what unique challenges does this present for scientific understanding?
- Lawhead identifies "How do we know that we can trust science?" as a surprisingly difficult foundational question. How might the proposed framework of "dynamical complexity" contribute to answering this question, particularly in the context of highly complex systems like the global climate?
