This glossary entry builds from definitions used in previous IPCC reports and the Millennium Ecosystem Assessment (MEA, 2005) 3. The ability of systems, institutions, humans and other organisms to adjust to potential damage, to take advantage of opportunities, or to respond to consequences. See also Adaptation, Adaptive capacity and Maladaptive actions (Maladaptation). They include a wide range of actions that can be categorized as structural, institutional, ecological or behavioural. The array of strategies and measures that are available and appropriate for addressing adaptation.
See also Adaptation options, Adaptive capacity and Maladaptive actions (Maladaptation). Soft adaptation limit: Options are currently not available to avoid intolerable risks through adaptive action.Hard adaptation limit: No adaptive actions are possible to avoid intolerable risks.The point at which an actor’s objectives (or system needs) cannot be secured from intolerable risks through adaptive actions. In some cases, incremental adaptation can accrue to result in transformational adaptation (Termeer et al., 2017 Tàbara et al., 2018) 2.Īdaptation that changes the fundamental attributes of a socio-ecological system in anticipation of climate change and its impacts. In natural systems, the process of adjustment to actual climate and its effects human intervention may facilitate adjustment to expected climate and its effects.Īdaptation that maintains the essence and integrity of a system or process at a given scale. In human systems, the process of adjustment to actual or expected climate and its effects, in order to moderate harm or exploit beneficial opportunities. Acceptability may vary from totally unacceptable/fully rejected to totally acceptable/fully supported individuals may differ in how acceptable policies or system changes are believed to be. The extent to which a policy or system change is evaluated unfavourably or favourably, or rejected or supported, by members of the general public (public acceptability) or politicians or governments (political acceptability).
See also Sustainable Development Goals (SDGs).Īcceptability of policy or system change The extent to which a policy or system change is evaluated unfavourably or favourably, or rejected or supported, by members of the general public (public acceptability) or politicians or governments (political acceptability). Beyond the 21st century, several elements of the climate system would continue to change even if the global mean temperatures remain stable, including further increases of sea level.Ģ030 Agenda for Sustainable Development A UN resolution in September 2015 adopting a plan of action for people, planet and prosperity in a new global development framework anchored in 17 Sustainable Development Goals (UN, 2015). Within the 21st century, several aspects play a role for the assessment of risk and potential impacts in 1.5☌ warmer worlds: the possible occurrence, magnitude and duration of an overshoot the way in which emissions reductions are achieved the ways in which policies might be able to influence the resilience of human and natural systems and the nature of the regional and sub-regional risks. There is no single 1.5☌ warmer world, and projections of 1.5☌ warmer worlds look different depending on whether it is considered on a near-term transient trajectory or at climate equilibrium after several millennia, and, in both cases, if it occurs with or without overshoot. 1.5☌ warmer worlds Projected worlds in which global warming has reached and, unless otherwise indicated, been limited to 1.5☌ above pre-industria l levels.
