ADAPTATION

Adjustments in ecological, social or economic systems in response to actual or expected climatic stimuli and their effects or impacts.

ADAPTATION LIMITS

The point at which an actor’s objectives (or system needs) cannot be secured from intolerable risks through adaptive actions.

ADAPTATION OPTIONS

The array of strategies and measures that are available and appropriate for addressing adaptation. They include a wide range of actions that can be categorized as structural, institutional, ecological or behavioral. See also Adaptation, Adaptive capacity and Maladaptive actions (Maladaptation).

ADAPTIVE CAPACITY

The ability of systems, institutions, humans and other organisms to adjust to potential damage, to take advantage of opportunities, or to respond to consequences. This glossary entry builds from definitions used in previous IPCC reports and the Millennium Ecosystem Assessment (MEA, 2005). See also Adaptation, Adaptation options and Maladaptive actions (Maladaptation).

ADDITIONAL OFFSETS

Carbon offsets that would not have occurred if the offset project had not been implemented. (This is one of four factors to consider when acquiring carbon offsets.)

ADDITIONAL/ADDITIONALITY

For a CDM project activity (non-A/R) or CPA (non-A/R), the effect of the CDM project activity or CPA to reduce anthropogenic GHG emissions below the level that would have occurred in the absence of the CDM project activity or CPA; or For an A/R or SSC A/R CDM project activity or CPA (A/R), the effect […]
