This chapter assesses the state of physical, biological and social knowledge concerning the Arctic andAntarctic ocean and cryosphere, how they are affected by climate change, and how they will evolve infuture. Concurrently, it assesses the local, regional and global consequences and impacts of individual andinteracting polar system changes, and it assesses response options to reduce risk and build resilience in thepolar regions. Key findings are:The polar regions are losing ice, and their oceans are changing rapidly. The consequences of this polartransition extend to the whole planet, and are affecting people in multiple ways.
