Climate response to aerosol geoengineering: a multi-method comparison
Muri, Helene; Tjiputra, Jerry; Otterå, Odd Helge; Adakudlu, Muralidhar; Lauvset, Siv Kari; Grini, Alf; Schulz, Michael; Niemeier, Ulrike; Kristjansson, Jon Egill (Journal article; Peer reviewed, 2018)Considering the ambitious climate targets of the Paris Agreement to limit global warming to 2°C, with aspirations of even 1.5°C, questions arise on how to achieve this. Climate geoengineering has been proposed as a potential ... -
Comparative Life Cycle Assessment of a Diesel Electric and a Battery Electric Ferry
Galaaen, Julie Sandnes (Master thesis, 2020)Abstract The maritime transport sector contributes to emissions of greenhouse gases (GHGs) and global warming. Mitigation strategies are needed to limit the climate changes on Earth. One possible measure is electrification ... -
Comparative Life Cycle Assessment of a Diesel Electric and a Battery Electric Ferry
Galaaen, Julie Sandnes (Master thesis, 2020)Maritim transport bidrar til utslipp av drivhusgasser og global oppvarming. Klimastrategier er nødvendige for å begrense klimaendringene på jorden. Et mulig tiltak er elektrifisering av ferger. For å undersøke miljøeffekter ... -
Evaluating climate geoengineering proposals in the context of the Paris Agreement temperature goals
Lawrence, Mark G.; Schãfer, Stefan; Muri, Helene; Scott, Vivian; Oschlies, Andreas; Vaughan, Naomi E.; Boucher, Olivier; Schmidt, Hauke; Haywood, Jim M.; Scheffran, Jürgen (Journal article; Peer reviewed, 2018)Current mitigation efforts and existing future commitments are inadequate to accomplish the Paris Agreement temperature goals. In light of this, research and debate are intensifying on the possibilities of additionally ... -
Global Shipping Emissions from a Well-to-Wake Perspective: The MariTEAM Model
Kramel, Diogo; Muri, Helene; Kim, YoungRong; Lonka, Radek; Nielsen, Jørgen Bremnes; Ringvold, Anna L.; Bouman, Evert Alwin; Steen, Sverre; Strømman, Anders Hammer (Peer reviewed; Journal article, 2021)Improving the robustness of maritime emission inventories is important to ensure we fully understand the point of embarkment for transformation pathways of the sector toward the 1.5 and 2°C targets. A bottom-up assessment ... -
Global streamflow and flood response to stratospheric aerosol geoengineering
Wei, Liren; Ji, Duoying; Miao, Chiyuan; Muri, Helene; Moore, John C. (Journal article; Peer reviewed, 2018)Flood risk is projected to increase under future warming climates due to an enhanced hydrological cycle. Solar geoengineering is known to reduce precipitation and slow down the hydrological cycle and may therefore be ... -
Inequal responses of drylands to radiative forcing geoengineering methods
Park, Chang-Eui; Jeong, Su-Jong; Fan, Yuanchao; Tjiputra, Jerry; Muri, Helene; Zheng, Chunmiao (Journal article; Peer reviewed, 2019)Climate geoengineering has the potential to reduce global warming. However, the nonlinear responses of Earth's large‐scale circulation to climate geoengineering can exacerbate regional climate change, with potential ... -
Mitigation of the aviation sector – LCA of alternative fuels, and future scenarios
Enes, Jon (Master thesis, 2021)Luftfartssektoren står per i dag for 2,5% av verdas årlege CO2 utslepp og 5% av det årlege bidraget til global oppvarming. Det er forventa at utslepp frå sektoren fortset å auke i takt med aukande flytrafikk. Effektive ... -
Reconciling big data on trade statistics and ship traffic: a case study
Salgado Delgado, Mario Amin (Master thesis, 2018)Globalisation and its trend to increase the interaction between nations on a worldwide scale has booster the commercialisation of raw materials to unprecedented levels. From the large proportion that trade activities share ... -
The response of terrestrial ecosystem carbon cycling under different aerosol-based radiation management geoengineering
Lee, Hanna; Muri, Helene; Ekici, Altug; Tjiputra, Jerry; Schwinger, Jörg (Peer reviewed; Journal article, 2021)Geoengineering has been discussed as a potential option to offset the global impacts of anthropogenic climate change and at the same time reach the global temperature targets of the Paris Agreement. Before any implementation ... -
Storm Track changes in the Middle East and North Africa under stratospheric aerosol geoengineering
Karami, Khalil; Tilmes, Simone; Muri, Helene; Mousavi, Seyed Vahid (Peer reviewed; Journal article, 2020)As a potential approach to prevent dangerous climate change, stratospheric aerosol geoengineering (SAG) aims to reflect some incoming solar radiation into space and reduce temperatures. Previous modeling studies suggest ... -
Stratospheric Aerosol Geoengineering could lower future risk of 'Day Zero' level droughts in Cape Town
Odoulami, Romaric C.; New, Mark; Wolski, Piotr; Guillemet, Gregory; Pinto, Izidine; Lennard, Christopher; Muri, Helene; Tilmes, Simone (Peer reviewed; Journal article, 2020)Anthropogenic forcing of the climate is estimated to have increased the likelihood of the 2015–2017 Western Cape drought, also called 'Day Zero' drought, by a factor of three, with a projected additional threefold increase ... -
The climate effects of increasing ocean albedo: an idealized representation of solar geoengineering
