Numerous climate-related impacts already cause severe damage in many places and are projected to increase in the future . Adaptation can reduce these risks, often significantly, but limits to adaptation have already been reached or are being approached in some sectors and regions . While natural systems worldwide are changing in response to climate change, many are not adapting sufficiently quickly to retain their resilience in the face of current and projected future climate change . For human systems, numerous lines of evidence suggest that in many regions and sectors current infrastructure, settlement patterns, policies, practices and institutions remain inadequate for current changes in climate conditions . Inadequate or insufficient adaptation to current conditions is called an adaptation deficit.
