    The effective radiative forcings (including rapid adjustments) and feedbacks associated with an instantaneous quadrupling of the preindustrial CO2 concentration and a counterbalancing reduction of the solar constant are ...
  • Kristjansson, Jon Egill; Muri, Helene; Schmidt, Hauke (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Recent multimodel studies have shown that if one attempts to cancel increasing CO2 concentrations by reducing absorbed solar radiation, the hydrological cycle will weaken if global temperature is kept unchanged. Using a ...

    Climate model studies of the consequences of solar geoengineering are central to evaluating whether such approaches may help to reduce the harmful impacts of global warming. In this study we compare the sunshade solar ...
  • Ahlm, Lars; Jones, Andy; Stjern, Camilla Weum; Muri, Helene; Kravitz, Ben; Kristjansson, Jon Egill (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Marine cloud brightening through sea spray injection has been proposed as a climate engineering method for avoiding the most severe consequences of global warming. A limitation of most of the previous modelling studies on ...
