Methane

  1. Microbial methane release identified in inner Laptev Sea subsea permafrost
    Triple-isotopic analysis reveals old microbial methane from subsea permafrost drives methane release in the inner Laptev Sea, contrasting with thermogenic sources elsewhere on the Arctic shelf.
  2. Methane increases were linked mainly to wetlands in Africa and Asia
    Atmospheric methane growth peaked in 2020 driven by declining hydroxyl radicals and increased tropical wetland emissions in Africa and Asia, before declining through 2023.
  3. Result-based contracts appear more acceptable for dairy methane reduction
    Study integrating farmer preferences into cost-efficient design of agri-environmental contracts for methane mitigation in Polish dairy production.
  4. Cross-shelf methane cycling was detected in the Laptev Sea
    Biomarker analysis reveals enhanced methane cycling across the Laptev Sea shelf overlying thawing subsea permafrost, using C30 hopanoid isotopic signatures as time-integrated proxies for aerobic.
  5. Spatial changes in a Scotian Slope cold seep reveal complex seepage
    Lipidomic and geochemical analysis of a North Atlantic cold seep reveals complex microbial zonation dominated by ANME archaea with sulfate-reducing microbes across a carbonate mound.
  6. Lake Mai Ndombe emits multiple greenhouse gases year-round
    Study quantifies greenhouse gas emissions from Lake Mai Ndombe, Africa's largest humic lake, revealing sedimentary processes drive CO2, CH4, and N2O cycling and evasion.
