This section builds on the analogous chapter in AR5  to refine the definition of climate-related key risks  and criteria for identifying them , and describe a broad range of key risks by sector and region as identified by the authors of WGII AR6 . Based on this, eight clusters of key risks  are identified and assessed in terms of the conditions under which they would become severe. In addition, the section assesses variation in KRs and RKRs by the level of global average warming, socioeconomic development pathways, and levels of adaptation, and illustrates the implications from resulting dynamics in all risk dimensions  along a case study of densely populated river deltas . Last, interactions among RKRs are discussed .
