Sea level rise and public health: Glossary of terms
Adaptation – The process of adjustment to actual or expected climate and its effects, to moderate or avoid harms or exploit beneficial opportunities.1
Adaptive capacity – The ability of individuals, communities, institutions or people to adjust to potential damage, to take advantage of opportunities, or to respond to consequences of climate change.1
Brackish – A transitional area that hosts a combination of fresh and sea water.
Eco-anxiety – distress caused by climate change where people become anxious about their future.2
Eco-paralysis – the inability to act on environmental challenges due to a perception that they are intractable, inhibiting people from taking effective action.3
Exposure – The presence of people; livelihoods; species or ecosystems; environmental functions, services, and resources; infrastructure; or economic, social, or cultural assets in places and settings that could be adversely affected.1
Hazard – The potential occurrence of a climate-related event or stress that may cause loss of life, injury, or other impacts, as well as damage and loss to property, infrastructure, livelihoods, service provision, ecosystems, and environmental resources.1
Health – A state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.4
Impacts – The consequences of realized risks on natural and human systems, where risks result from the interactions of climate-related hazards (including extreme weather/climate events), exposure, and vulnerability.1
Psychoterratic syndromes – defined as earth-related mental illness where mental well-being is threatened by the severing of links between themselves and their home or territory.5
Representative Concentration Pathway (RCP) – Possible future scenarios for human-caused Greenhouse Gas (GHG) emission trends based on future emissions, deforestation, population growth and many other factors.6
- RCP 2.6: low global emission scenario, based on strong mitigation actions that indicate global warming levels of 0.9 to 2.3 °C by 2090.
- RCP 4.5: medium global emission scenario, based on mitigation measures that indicate average global warming levels of 1.7 to 3.2 °C by 2090.
- RCP 8.5: high global emission scenario that indicate average global warming levels of 3.2 to 5.4 °C by 2090. This scenario is often used as a default for planning because humans are currently on this “worst case” trajectory.
Risk – The potential for adverse consequences for human or ecological systems. Risk results from the interaction of vulnerability, its exposure over time (to the hazard), as well as the (climate-related) hazard and the likelihood of its occurrence.1
Sea level rise – An elevation in sea level due to the increased volume of water in global oceans caused by melting of glaciers and sea ice and thermal expansion of sea water, resulting in increased risk of coastal flooding and inundation.7
Sensitivity – The degree to which a system is affected, either adversely or beneficially, by climate-related stimuli. The effect may be direct (e.g., a change in crop yield in response to a change in the mean, range, or variability of temperature) or indirect (e.g., damage caused by an increase in the frequency of coastal flooding due to sea-level rise).8
Social determinants of health – include income and social protection; education; employment and job security; working life conditions; food security; housing, basic amenities and the environment; early childhood development; social inclusion and non-discrimination; lack of structural conflict; and access to affordable health services of decent quality.9
Solastalgia -- characterized by the distress that is produced by environmental change affecting people while they are still living in their home environment.5
Storm surge – the difference between expected (astronomical tides) and experienced water levels due to meteorological conditions. Strong onshore winds and low atmospheric pressure for example can cause positive storm surge resulting in higher water levels than expected.10
Vulnerability – The propensity or predisposition to be adversely affected. Vulnerability can be due to individual susceptibility, geographic location, socio-economic factors, and a wide range of other factors that determine an individual or community’s susceptibility to harm and ability to cope with an event.8
