A chaque expiration, nous envoyons du dioxyde de carbone gazeux dans l'atmosph\u00e8re. Le dioxyde de carbone est un exemple de gaz \u00e0 effet de serre \u2013 gaz qui enferment la chaleur.<\/p>\n<\/div>\n

Au cours des 100 derni\u00e8res ann\u00e9es, les quantit\u00e9s de dioxyde de carbone dans l\u2019atmosph\u00e8re ont augment\u00e9 r\u00e9guli\u00e8rement. La plus grande partie de cette augmentation est due aux activit\u00e9s humaines, par exemple la combustion du p\u00e9trole ou du charbon ou la d\u00e9forestation.<\/p>\n

Les for\u00eats absorbent une grande quantit\u00e9 du dioxyde de carbone pr\u00e9sent dans l'air. Mais ce carbone stock\u00e9 est rel\u00e2ch\u00e9 dans l'atmosph\u00e8re lors du d\u00e9boisement ou du br\u00fblage des arbres.<\/p>\n

Les donn\u00e9es des satellites d\u00e9montrent que la terre semble se r\u00e9chauffer. La plupart des scientifiques pensent qu'il existe un lien entre le r\u00e9chauffement de la plan\u00e8te et l'augmentation des gaz \u00e0 effet de serre. C'est ce qu\u2019on appelle g\u00e9n\u00e9ralement 'l'effet de serre'.<\/p>\n

Les satellites tels que Envisat de l'ESA nous aident \u00e0 en savoir plus sur les variations climatiques mondiales et \u00e0 pr\u00e9dire ce qui pourrait se passer \u00e0 l\u2019avenir.<\/p>\n

Certains instruments sur Envisat produisent des cartes quotidiennes pour toute la plan\u00e8te des gaz \u00e0 effet de serre tels que le m\u00e9thane (couramment utilis\u00e9 dans les cuisini\u00e8res et pour le chauffage). D'autres pr\u00e9sentent les variations de temp\u00e9rature, de neige, de glace, les \u00e9volutions des lacs et de la couverture foresti\u00e8re.<\/p>\n

Ces informations sont indispensables pour la mise en \u0153uvre des accords internationaux de r\u00e9duction de la production des gaz \u00e0 effet de serre.<\/p>","protected":false},"excerpt":{"rendered":"
