This Cross Chapter Paper  assesses the impacts, risks and adaptation implications resulting from the physical and chemical changes in the polar regions that were detailed in the Intergovernmental Panel on Climate Change  Working Group I  contribution to the IPCC 6th Assessment Report  . Several key WGI AR6 findings have important implications for natural and human systems in polar regions. Warming and wetting have persisted as key climatic impact drivers in polar regions  and will very likely2 continue to 2100  with cascading climate effects regarding heatwaves, fire, weather, floods and heavy precipitation, river runoff, snowfall, glaciers and ice sheets , permafrost, lake, river and sea ice, relative sea level and coastal flooding and erosion  . They represent major climate hazards in all key risks for polar regions . Key points of departure for this CCP also include IPCC 5th Assessment Report   and the Polar Regions chapter in the Special Report on the Ocean and Cryosphere in a Changing Climate  . SROCC assessed physical, biological and social systems concerning the Arctic and Antarctic Oceans and cryosphere, and how they are affected by current and future climate change. This CCP assesses the rapidly increasing evidence that has been published since AR5 and SROCC, and advances previous IPCC assessments. First, results from the Coupled Model Intercomparison Projects  are an important advance since SROCC, which improve the certainty and resolution of projections of the main climate impact drivers and the risks they have for polar systems . Second,
