Climate concepts for supporting political goals of mitigation and adaptation: The case for “climate crisis”

Abstract

Climate concepts are crucial to understand the effects of human activity on the climate system scientifically, and to formulate and pursue policies to mitigate and adapt to these effects. Yet, scientists, policymakers, and activists often use different terms such as “global warming,” “climate change,” “climate crisis,” or “climate emergency.” This advanced review investigates which climate concept is most suitable when we pursue mitigation and adaptation goals in a scientifically informed manner. It first discusses how survey experiments and social science reviews on climate frames draw normative recommendations about which terms to use for public climate communication. It is suggested that such normative claims can be refined by including the scientific alongside lay uses of a climate concept, and by using explicit assessment conditions to evaluate how suitable a concept is for formulating mitigation and adaptation goals. Drawing on philosophical theories of conceptual change in science and conceptual engineering, a novel framework with two assessment conditions is introduced and then applied to “global warming,” “climate change,” “climate emergency,” and “climate crisis.” The assessment suggests that currently, “climate crisis” is most suitable to formulate and pursue climate mitigation and adaptation goals. Using this concept promotes the epistemic goals of climate science to a high degree, bridges scientific, political, and activist discourse, and fosters for democratic participation when articulating climate policies.This article is categorized under: The Social Status of Climate Change Knowledge > Climate Science and Decision Making The Social Status of Climate Change Knowledge > Knowledge and Practice Perceptions, Behavior, and Communication of Climate Change > Communication
