Climate and Environment

An environment is a complex of surrounding circumstances, conditions, or influences in which a thing is situated or is developed, or in which a person or organism lives, modifying and determining its life or character. The environment of an organism includes both physical properties, which can be described as the sum of local abiotic factors such as insolation (sunlight), climate, and geology, and biotic factors, which are other organisms that share its habitat.

Natural environment is thus the result from interactions between : atmosphere, ecosystems (including vegetation), and water.

Climate is the average and variations of weather in a region over long periods and of time. It is the result of interactions between its five components or spheres: Atmosphere, Hydrosphere, Cryosphere, Biosphere, Lithosphere

Look also to the video “La « musique des sphères »: le climat au XXe siècle”. In this video, Yves M. Tourre (Meteo-France and Columbia University) compares climate variability as the music perceived from a Symphony Orchestra.
