Scientists turn back time to track methane emissions on Mars
WebOn the contrary, three to four times higher contributions of methane emissions during the autumn freeze than that of the spring thaw were observed from a tundra ecosystem in Alaska, United States ( Bao et al., 2024 ). Another study found a methane emission burst in the early winter from tundra regions as well ( Mastepanov et al., 2008 ). Web16 jun. 2024 · Methane is a simple molecule formed by one atom of carbon (C) and four atoms of hydrogen (H). The warming effect of one molecule of methane is equivalent to 25 molecules of CO 2, making it a super-powerful greenhouse gas. Web27 apr. 2024 · by Fanni Daniella Szakal 27 April 2024.
