Climate change is a serious ecological problem that faces humanity in the modern world because of its destructive effects on both human beings and on the physical natural environment where they live. The current study deals with the appraisal patterns used by some heads of states and officials in some of their speeches delivered during COP27 held in Egypt in 2022 in Sharm El-Sheikh. The study is also cross-linguistic as it clarifies similarities and/or differences between English and Arabic regarding the appraisal patterns used. Moreover, it offers a quantitative analysis concerning the frequency of the appraisal patterns used in the data under investigation. The methodology adopted is that of Stibbe (2015a), and the focus is on the model devoted to appraisal patterns. The study reveals a number of important findings, one of which is that implicit positive appraisal is the most commonly used technique in the analysed data.
