EXP: ist neben Stickstoff, Sauerstoff und sogenannten Edelgasen ein natürlicher Bestandteil der Luft und eines der bedeutendsten Treibhausgase; hat in dieser Funktion eine entscheidende Rolle für das Klima: CO2 absorbiert einen Teil der von der Erde in das Weltall abgegebenen Wärme und strahlt diese zurück auf die Erde
EXP: it is one of the most important greenhouse gases linked to global warming, but it is a minor component of Earth’s atmosphere, formed in combustion of carbon-containing materials, in fermentation, and in respiration of animals and employed by plants in the photosynthesis of carbohydrates; the presence of the gas in the atmosphere keeps some of the radiant energy received by Earth from being returned to space, thus producing the so-called greenhouse effect
EXP: se trouve à l’état naturel dans l’atmosphère; joue un rôle primordial dans le cycle du carbone sur Terre et subit en permanence des transferts entre les différents milieux; est le principal gaz à effet de serre à l’état naturel, avec la vapeur d’eau
EXP: si trova libera in natura, disciolta nelle acque e combinata; è un prodotto della combustione del carbone, degli idrocarburi e delle sostanze organiche e uno dei principali gas a fetto serra; la sua concentrazione è andata aumentando a causa del consumo crescente dei combustibili fossili, provocando un aggravamento dell’effetto serra
