    Large amounts of methane are stored in continental margins as gas hydrates. They are stable under high pressure and low temperature, but react sensitively to environmental changes. Bottom water temperature and sea level ...
  • Johansen, Camilla Weum (Master thesis / Hovedoppgave, 2005)
    In spite of increasing surface temperatures, a falling trend in surface insolation has been observed over the past 50 years at stations worldwide, and a link to anthropogenic aerosols has been suggested. In the present ...
  • Gaina, Carmen; Jakob, Johannes (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Many of our planet's “crises” were the result of sudden changes in plate tectonic configuration or catastrophic outbursts of volcanism caused by mantle plume impingement at the base of the lithosphere. At the Paleocene-Eocene ...
  • Brenna, Hans; Kutterolf, Steffen; Krüger, Kirstin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Large explosive tropical volcanic eruptions inject high amounts of gases into the stratosphere, where they disperse globally through the large-scale meridional circulation. There is now increasing observational evidence ...

    Global mean sea level is an integral of changes occurring in the climate system in response to unforced climate variability as well as natural and anthropogenic forcing factors. Its temporal evolution allows changes (e.g., ...
  • Wei, Liren; Ji, Duoying; Miao, Chiyuan; Muri, Helene; Moore, John C. (Journal article / Tidsskriftartikkel / PublishedVersion; 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 ...
  • Svensen, Henrik; Torsvik, Trond Helge; Callegaro, Sara; Augland, Lars Eivind; Heimdal, Thea Hatlen; Jerram, Dougal Alexander; Planke, Sverre; Pereira, Egberto (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Gondwana was an enormous supertarrane. At its peak, it represented a landmass of about 100 × 106 km2 in size, corresponding to approximately 64% of all land areas today. Gondwana assembled in the Middle Cambrian, merged ...
