Adaptation
Adjustment in natural or human systems in response to changes or expected, or their effects, that mitigates or enhances the damage profits.

Natural or climatic algae
Natural/climatic process or phenomenon that can cause loss of life, injury or other health effects, damage to property, loss of means and services, socio-economic disruption, or damage
the environment.

Early warning
A set of capacities needed to produce and disseminate timely and timely alert bulletins enabling threatened individuals, communities and organizations to prepare and act appropriately in a timely manner to reduce the risk of damage or loss.

Mitigation
All measures or policies taken to reduce emissions of gas greenhouse gases in the atmosphere from emission sources or from carbon traps already present in the atmosphere in natural or artificial arrangements called wells carbon sequestration, e.g. forests.

Adaptability
Capacity of a natural or human system to adapt to climate change (e.g. climate variability and extreme events) so as to reduce the potential damage, taking advantage of opportunities and dealing with consequences anthropogenic climate change.

Climate change
Climate change attributed directly or indirectly to human activity affecting the composition of the global atmosphere, which is observed over a long period of time.

Capacity development
Process by which people, organizations and society stimulate and develop over time, to achieve economic and social objectives, improved knowledge, systems and institutions.

Adverse effects of climate change
Changes in the physical environment or biota due to changes and which have significant adverse effects on composition, resistance or productivity of natural and managed ecosystems, on the functioning of socio-economic systems or on human health and well-being

Emissions
The release of greenhouse gases or precursors of such gases into the atmosphere above in an area and during a given period.

Greenhouse gases
Gases from the atmosphere, both natural and anthropogenic, which absorbs and emits radiation heat and infrared radiation, emitted by the Earth's surface, the atmosphere itself, and by clouds (e.g. carbon dioxide, methane, nitrous oxide, ozone,
water vapour, chlorinated or fluorinated compounds...).

Adaptation measures
Measures to address impacts or impacts of climate change.

Mitigation measures
Means to avoid or reduce the importance of an impact, usually for changes to the project or modalities.

Preventive measures
Actions to eliminate or reduce the danger of climate change an acceptable level.

Climate model
Digital representation of the climate system, based on physical properties, their interactions and feedback processes and which takes into account all or part of its known properties.

Prevention
A set of activities to completely avoid the negative impact of hazards, and minimize environmental, technological and biological disasters Associated.

Forecast
Statistical declaration or estimate defined regarding the probability of a future event or specific conditions for a given area.

Projection
Indication of the possible future development of a size or set of magnitudes, often calculated using a model. Projections differ from forecasts in this respect. they are based on assumptions concerning, for example, the evolution of socio-economic conditions or techniques that may or may not be realized and are therefore subject to high uncertainty.

Resilience
Capacity of a system, community or society exposed to the risks of resisting, to absorb, receive and correct the effects of a hazard in a timely and appropriate manner the preservation and restoration of its essential structures and basic functions.
Capacity of a social or ecological system to absorb disturbances while maintaining its basic structure and modes of operation, the capacity to organise and the capacity adapt to stress and change.

Disaster risk
Potential for disaster, in terms of human lives, health states, means of services, which could occur within a community or community. society, in the future.

Climate scenario
Likely and often simplified representation of the future climate, based on a set inherently coherent climatological relations and expressly established for identify the potential consequences of anthropogenic climate change, which serves to often feeding impact models. Climate projections are frequently used climate scenarios, although they generally require additional information, e.g. on the climate currently observed.

Climate change scenario
Difference between a climate scenario and the current climate.

Sensitivity
The ability of a system to respond to changing climate conditions, for example: degree of change in the composition, structure and functioning of a and in particular its primary productivity, as compared to a change in
temperature or precipitation given.

Climate system
A combination of atmosphere, hydrosphere, biosphere and geosphere, and their interactions.

Vulnerability
The characteristics and circumstances of a community or system that make it likely to be affected by a danger. Vulnerability defines the extent to which system can be degraded or damaged by climate change. she depends no
only sensitivity, but also system adaptability has new conditions climate change. This concept combines a society's level of physical threat with its capacity
adaptation.
