    • Assessment of the Remaining Carbon Budget: Incorporating Arctic Amplification in a Simple Response Model 

      Johansen, Andreas (Master thesis; Mastergradsoppgave, 2020-06-15)
      Remaining carbon budgets (RCBs) quantify the total amount of CO2 that can still be emitted into the atmosphere while keeping the global mean surface temperature below a specific target. However, there is significant uncertainty in RCBs estimates. This thesis develops a Simple Response Model (SRM) to explore the uncertainties in RCBs. We use temperature response functions estimated from multi-box ...

    • Estimating Remaining Carbon Budgets Using Temperature Responses Informed by CMIP6 

      Rypdal, Martin Wibe; Boers, Niklas; Fredriksen, Hege-Beate; Eiselt, Kai-Uwe; Johansen, Andreas; Martinsen, Andreas Rostrup; Mentzoni, Endre Falck; Graversen, Rune; Rypdal, Kristoffer (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-12)
      A remaining carbon budget (RCB) estimates how much CO2 we can emit and still reach a specific temperature target. The RCB concept is attractive since it easily communicates to the public and policymakers, but RCBs are also subject to uncertainties. The expected warming levels for a given carbon budget has a wide uncertainty range, which increases with less ambitious targets, i.e., with higher CO2 ...
