Adaptation initiatives have positive impacts on reducing climate change risks to people and ecosystems. The Working Group II (WGII) contribution to the Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) provides a comprehensive assessment of the feasibility and effectiveness of adaptation, and an in-depth assessment of adaptation limits and maladaptation. Adaptation actions are increasing at the individual, local, regional, and national levels, but the risks of maladaptation should be considered when making decisions. Six feasibility dimensions (economic, technological, institutional, social, environmental, and geophysical) are used to evaluate the potential feasibility of 23 adaptation options, which are distributed in land & ocean and ecosystems, urban & rural and infrastructure systems, energy systems, and cross-sectoral. Among those adaptation options, the forest-based adaptation, the resilient power systems, and the energy reliability have high confidence and high feasibility. The feasibility and effectiveness of adaptation options will decrease with climate warming, and multiple options are needed to reduce climate change risks in the future.

Key words: IPCC, Sixth Assessment Report (AR6), Adaptation, Climate change, Impacts
