However, uncertainties about wetland extent and CH4 production have led to large variations in modelled CH4 emission trends2,6. These results demonstrate the importance of tropical ice cores on the reconstruction of CH4 variability and latitudinal distribution.

3,768m asl). We find that the trends and magnitudes of our CH4 record are broadly consistent with polar records7. Our 13C-CH4 measurements (from approximately 1530CE to 1999CE) align with isotope values8 consistent with a dominant tropical CH4 source. Integration of our record into an atmospheric four-box model suggests a sustained equatorial dominance of CH4 source strength over the past two millennia. Our findings indicate that equatorial CH4 emissions are higher than previous estimates based only on polar ice core data,然而。
