      Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere in a changing climate – the “global carbon budget” – is important to better ...

    • Norske havforsuringsdata og FNs bærekraftsmål 14.3 

      Skjelvan, Ingunn; Jeansson, Emil (Research report, 2020)
      IOC (Intergovernmental Oceanographic Commision) har hatt ansvaret for å utvikle en indikator for havforsuring, som er knytta til FN sitt bærekraftsmål for livet i havet. Land, forskere og datasentre har blitt bedt om å ...
