Special Report on Extremes (SREX)
AR5 WGI - Climate
AR5 WGII – Impacts & AdaptAR5 WG III - Mitigation
IPCC SREX & AR5
Global Biodiversity Outlook 4
• Strong coordination of concepts, typologies, language, analyses
• Shared overall chapter structure
• Despite strong coordination, still lacking in study of interactions between Aichi Targets
Target 1
Target 2
Target 20
Synthesis & interactions
Coordination & synthesis meetings
• SREX thematic assessment independent. Working Groups meet independently
• Weak integration across working groups seen as a serious problem.
• Good use of SREX in some parts of AR5, but poorly exploited in WGII
•••
Lessons learned from other assessments about integration

Greater coupling
• Thematic assessments have regional focus, with global synthesis
• Greater coordination of concepts, typologies, language, analyses
• Shared overall chapter structure between thematic & regional assessments
• Potentially improved analyses of interactions between drivers, impacts and responses.
