Adaptation to climate change refers to reducing the vulnerability of people and the environment to climate change impacts. Adaptation measures are typically classified as "soft", .e.g., policies or "hard", e.g., hurricane proofing homes. Climate change impacts are already affecting developing countries, particularly the poor and most vulnerable that have fewer social, technological, and financial resources for adaptation. The Bali Action Plan identified the need for action on adaptation, particularly for enhanced action on the provision of financial resources, investment and technology to support action on adaptation.
