Certains microbes vivant dans des milieux aquatiques, en zones humides et dans les rizi\u00e8res \u00e9mettent du m\u00e9thane \u00e0 la place du gaz carbonique lorsqu\u2019ils respirent. Alors que la temp\u00e9rature plan\u00e9taire augmente, les \u00e9missions de m\u00e9thane de ces organismes augmenteront aussi. Une nouvelle \u00e9tude montre que ces \u00e9missions augmenteront plus vite avec la temp\u00e9rature que les \u00e9missions de gaz carbonique provenant de la respiration et de la photosynth\u00e8se d\u2019autres organismes vivants. Puisque le m\u00e9thane est un gaz \u00e0 effet de serre plus puissant que le CO2, l\u2019augmentation du ratio entre le m\u00e9thane et le gaz carbonique pourrait avoir des cons\u00e9quences sur les boucles de r\u00e9troaction entre les changements climatiques et le cycle du carbone.<\/p>\n
