Pacific Islands Regional Climate Assessment (PIRCA) is a collaborative effort to assess climate change indicators, impacts, and adaptive capacity of the Hawaiian archipelago and the US-Affiliated Pacific Islands (USAPI). PIRCA engages federal, state, and local government agencies, non-government organizations, academia, businesses, and community groups to inform and prioritize their activities in the face of a changing climate.
Together over 100 scientific experts and practitioners contributed to the 2012 PIRCA report, an integrated regional assessment that serves as a contribution to the Third National Climate Assessment. The 2012 PIRCA report examines climate change impacts in Hawai‘i and the USAPI and also assesses the adaptive capacity of Pacific Island communities.
The 2012 assessment represents the beginning of a sustained process of assessment and information exchange among scientists, businesses, governments, and communities in the Pacific Islands region. In conjunction with other regional and national assessments, the 2012 PIRCA report provides information for decision makers seeking to better understand how climate variability and change impact the Pacific Islands region and its communities.
