The Intergovernmental Panel<strong>on</strong> <strong>Climate</strong> <strong>Change</strong> (IPCC) defines adaptati<strong>on</strong> as ‘adjustment in natural or human systems inresp<strong>on</strong>se to actual or expected climatic stimuli or their effects, which moderates harm or exploitsbeneficial opportunities.’ Adaptati<strong>on</strong> can also be thought of as learning how to live with thec<strong>on</strong>sequences of climate change.The ability of a system to adjust to climate change (including climate variability <strong>and</strong> extremes), tomoderate potential damages, to take advantage of opportunities <strong>and</strong> to cope with thec<strong>on</strong>sequences. (CLIMATE-ADAPT Glossary)A systematic process for c<strong>on</strong>tinually improving management policies <strong>and</strong> practices by learning fromthe outcomes of previous policies <strong>and</strong> practices.Article 6(3) of the Habitats Directive requires an appropriate assessment (also referred to as‘Habitats Directive assessment’ or ‘Natura 2000 assessment’) to be carried out where any plans orprojects that are not directly linked to the management of that site may have a significant effect <strong>on</strong>the c<strong>on</strong>servati<strong>on</strong> objectives <strong>and</strong> would ultimately affect the integrity of the site. Integrity can bedefined as the ability of the site to fulfil its functi<strong>on</strong> to c<strong>on</strong>tinue to support protected habitats orspecies. Annex I to the Habitats Directive includes a full list of protected habitats <strong>and</strong> Annex II ofprotected species.A descripti<strong>on</strong> of the present <strong>and</strong> future state, if the plan or programme (PP) is not implemented,taking <strong>into</strong> account changes resulting from natural events <strong>and</strong> from other human activities.The C<strong>on</strong>venti<strong>on</strong> <strong>on</strong> Biological Diversity (CBD) defines biological diversity as ‘the variability am<strong>on</strong>gliving organisms from all sources including, inter alia, terrestrial, marine <strong>and</strong> other aquaticecosystems <strong>and</strong> the ecological complexes of which they are part; this includes diversity withinspecies, between species <strong>and</strong> of ecosystems’ (Article 2).Measures taken to compensate for any residual significant, adverse impacts that cannot beavoided, minimised <strong>and</strong>/or rehabilitated or restored, in order to achieve ‘no-net-loss’ or a ‘net-gain’of biodiversity. Offsets can take the form of positive management interventi<strong>on</strong>s such as restorati<strong>on</strong>of degraded habitat, arrested degradati<strong>on</strong> or averted risk, protecting areas where there isimminent or projected loss of biodiversity.Directive 2009/147/EC of the European Parliament <strong>and</strong> of the Council of 30 November 2009 <strong>on</strong> thec<strong>on</strong>servati<strong>on</strong> of wild birds [codified versi<strong>on</strong>], OJ L 20, 26.1.2010, p. 7.The removal of carb<strong>on</strong> from the atmosphere <strong>and</strong> its storage in carb<strong>on</strong> sinks (such as oceans, forestsor soils) through physical or biological processes, such as photosynthesis.An absorber of carb<strong>on</strong> (usually in the form of CO 2 ). Natural carb<strong>on</strong> sinks include forests <strong>and</strong> otherecosystems that absorb carb<strong>on</strong>, thereby removing it from the atmosphere <strong>and</strong> offsetting CO 2emissi<strong>on</strong>s. (Modified from EEA Glossary)Usually defined as the ‘average weather’, or more rigorously, as the statistical descripti<strong>on</strong> in termsof the mean <strong>and</strong> variability of relevant quantities of variables such as temperature, precipitati<strong>on</strong>,<strong>and</strong> wind, over a period of time. The c<strong>on</strong>venti<strong>on</strong>al period of time over which weather is averagedto calculate climate is 30 years, as defined by the World Meteorological Organisati<strong>on</strong> (WMO).(Modified from IPCC)The IPCC defines climate change as ‘...any change in climate over time, whether due to naturalvariability or as a result of human activity.’ The United Nati<strong>on</strong>s Framework C<strong>on</strong>venti<strong>on</strong> <strong>on</strong> <strong>Climate</strong><strong>Change</strong> (UNFCCC) defines it specifically in relati<strong>on</strong> to human influence as: ‘a change of climatewhich is attributed directly or indirectly to human activity that alters the compositi<strong>on</strong> of the globalatmosphere <strong>and</strong> which is in additi<strong>on</strong> to natural climate variability observed over comparable timeperiods.'A metric measure used to compare emissi<strong>on</strong>s from various GHGs based up<strong>on</strong> their global warmingpotential (GWP). Carb<strong>on</strong> dioxide equivalents are comm<strong>on</strong>ly expressed as ‘milli<strong>on</strong> metric t<strong>on</strong>nes ofcarb<strong>on</strong> dioxide equivalents (MMTCDE)’.The incremental effects of an acti<strong>on</strong> PP when added to other past, present, <strong>and</strong> reas<strong>on</strong>ablyforeseeable future acti<strong>on</strong>s. Cumulative effects can result from individually minor but collectivelysignificant acti<strong>on</strong>s taking place over a period of time.Envir<strong>on</strong>mental effects caused directly by the implementati<strong>on</strong> of a PP.The Ec<strong>on</strong>omics of Ecosystem Services <strong>and</strong> <strong>Biodiversity</strong> (TEEB) study defines ecosystem services as:‘the benefits people receive from ecosystems’. TEEB also sets out the basis of human dependence<strong>on</strong> the natural envir<strong>on</strong>ment. The European-led study builds <strong>on</strong> the United Nati<strong>on</strong>s MillenniumEcosystem Assessment, which defined four categories of ecosystem services that c<strong>on</strong>tribute tohuman well-being:6 <str<strong>on</strong>g>Guidance</str<strong>on</strong>g> <strong>on</strong> integrating climate change <strong>and</strong> biodiversity <strong>into</strong> SEA
