Climate change adaptation refers to efforts by society or ecosystems to prepare for and adjust to future climate change through protective or opportunistic adjustments. It involves confronting climate risks, preparing for their impacts, and coping with their effects in order to manage risk and unlock opportunities. Barriers to adaptation include lack of awareness, information and resources as well as uncertainty around climate impacts. Adaptation strategies span early-response systems, diversification, infrastructure design, and resilience building across sectors like jobs, resources, healthcare, economic development and knowledge.
