This paper explores the epistemological basis for economic prognostications of climate change activists arising from, arguably, the most important scientific problem confronting modern society: the facts, beliefs and theories associated with the measurement, causes, impact and mitigation of climate change. This facilitates identification of the role that rhetoric plays in activist claims associated with the economics of global warming and climate change. Following a rudimentary discussion of ancient views on rhetoric, the connection of rhetoric with anti-foundational epistemology and language is identified. Criteria for determining when language is rhetorical are specified. Exploiting this philosophical background, mitigation proposals of climate change activists derived from models of climate change economics are critiqued.

本文探讨了气候变化活动家进行经济预测的认识论基础，这可能是现代社会面临的最重要的科学问题：与气候变化的度量，成因，影响和缓解相关的事实，信念和理论。这有助于确定修辞在与全球变暖和气候变化的经济学相关的激进主义者主张中所起的作用。在对古代关于修辞学的观点进行了基本的讨论之后，确定了修辞学与反基础认识论和语言之间的联系。规定了确定语言何时是口头表达的标准。在这种哲学背景下，人们从气候变化经济学的模型中提出了缓解气候变化活动家的建议。
