The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.

North America
Chapter 14 assesses climate change impacts and risks, vulnerability as well as barriers and options for adaptation and climate resilient development in North America.
CHAPTER 15
Small Islands
Chapter 15 assesses climate change impacts and risks, vulnerability as well as barriers and options for adaptation and climate resilient development in Small Islands.
CHAPTER 16
Key risks across sectors and regions
Chapter 16 synthesizes observed climate change impacts, adaptation-related responses, limits to adaptation and the key risks identified across sectors and regions.
CHAPTER 17
Decision-making options for managing risk
Chapter 17 assesses the options, processes and enabling conditions for climate risk management as well as the governance and applicability of adaptation options in various contexts.
CHAPTER 18
Climate resilient development pathways
Chapter 18 assesses the ways climate impacts and risks hinder Climate Resilient Development (CRD) in different sectoral and regional contexts as well as the ways of achieving CRD.
