Tropical wetlands are widely considered the largest natural source of atmospheric methane (CH4)1, 2, 3–4. However, uncertainties about wetland extent and CH4 production have led to large variations in modelled CH4 emission trends2,3. Most historical reconstructions rely on data from polar ice cores, which cannot fully...

Despite their importance for global CH4 biogeochemistry, there is limited evidence on seasonal patterns in CH4 stable isotope composition from peatlands. We conducted a 2.5‐year study investigating seasonal changes in CH4 fluxes and dual‐stable isotopes (δ13C, δ2H) in an ombrotrophic peat bog in Northern England. We pe...

Thawing permafrost can amplify climate change by releasing previously stored carbon, but observations of this feedback come mainly from the Arctic. Ice‐free Antarctic terrains are generally regarded as minor CO

Determining the climatic conditions under which the Greenland Ice Sheet (GrIS) was smaller than present is important to quantify GrIS sensitivity to climate change. We use biomarkers in sediment collected beneath the GrIS at Camp Century, northwestern Greenland, to reconstruct summer temperature and atmospheric circu...

Late Pleistocene climate in the European Alps was marked by large, orbitally driven fluctuations in temperature, precipitation, and ice extent. Reconstructing mountain glaciation prior to the Last Glacial Maximum remains challenging, however, because glacial deposits are often eroded or reworked. Here we present a...

Flores Island, situated in the Azores archipelago, is a volcanic island formed by overlapping stratovolcanoes. The island hosts several volcanic freshwater bodies, some of them present poor ecological state. Flores Island maar craters lakes were studied to assess greenhouse gas emissions, through investigation of tempo...
