Direkte og indirekte klimaeffekter av ozonnedbrytende stoffer
Fuglestvedt, Jan S.; Seip, Hans Martin (1999:07, Working paper, 1999)Viktige ozonnedbrytende stoffer som KFK-11 og KFK-12 er sterke drivhusgasser med direkte oppvarmingseffekt. Men fordi disse gassene bryter ned ozonlaget, har de også flere indirekte effekter som sannsynligvis virker ... -
Earlier emergence of a temperature response to mitigation by filtering annual variability
Samset, Bjørn Hallvard; Zhou, C.; Fuglestvedt, Jan S.; Lund, Marianne Tronstad; Marotzke, J.; Zelinka, M.D. (Journal article; Peer reviewed, 2022)The rate of global surface warming is crucial for tracking progress towards global climate targets, but is strongly influenced by interannual-to-decadal variability, which precludes rapid detection of the temperature ... -

Fuglestvedt, Jan S.; Jonson, J. E.; Isaksen, Ivar S. A. (1993:05, Research report, 1993)The observed reductions in stratospheric ozone since the late 1970s are likely to have affected the penetration of UV radiation into the troposphere.
