effet de serre anthropique

OBS: Les chlorofluorocarbures, ou CFC, sont des gaz à effet de serre presque exclusivement d'origine anthropique. Le dioxide de carbone, ou CO2, bien qu'il soit naturellement présent dans l'atmosphère, atteint aujourd'hui des concentrations beaucoup plus élevées qu'avant l'ère industrielle.
OBS: Ces termes s'emploient par opposition à ""effet de serre naturel"".

CONT: Because carbon dioxide is still the biggest contributor to the anthropogenic greenhouse effect, and because it was the first to be identified, the experts measure the greenhouse effect of other trace gases in terms of their carbon dioxide equivalent - this also makes it easier to take on board and update the estimates of future climatic changes based on the carbon dioxide effect alone, simply by adding in the appropriate extra amount of carbon dioxide.
OBS: These terms are to be contrasted with ""natural greenhouse effect"".

CONT: ... as intensas atividades humanas desenvolvidas no último século vêm colaborando cada vez mais para o aumento das concentrações desses gases de efeito estufa, provocando, assim, o que podemos chamar de efeito estufa antrópico ou antropogênico, isto é, causado pela ação do homem.
