This provides only apartial picture ofLoss andDamage, as theremaybenegative consequences from climate change that are not related to extremeweather events. Such impacts occur becauseofmoregradual shifts, often called slow-onset processes, in climate variables such as average (seasonal) land-surface temperatures, average rainfall, as wellasothervariables,suchassea-levelrise, lossoficeandsnow-cover,andincreas- ing temperatures of water bodies such as rivers, lakes and oceans. These impacts include shifts or loss of ecosystems and biodiversity, coastal erosion and loss of land,submergenceof low-lyingislandsandatolls,changes inagriculturalyield,and loss of indigenous and cultural practices and traditions.Many of such impacts are treated in this book in the chapters by Serdeczny (2018) and van der Geest et al.
