As in AR5 Oppenheimer et al. , major clusters of KRs are further analysed, and here referred to as 'representative key risks' . RKRs were defined in a three-step process . First, half of Chapter 16 authors independently mapped the KRs  to a set of candidate RKRs. Second, all Chapter 16 authors discussed the set of independent results and proposed a list of RKRs, considering scope and overlap. Third, this proposal was discussed with a consultative group of about 20 WGII AR6 authors from other chapters closely involved in the KR identification process, and a final list of eight RKRs was identified .
