Afforestation affects rain-on-snow climatology over Norway
Mooney, Priscilla A.; Lee, Hanna (Peer reviewed; Journal article, 2022)Rain-on-snow (ROS) events are most commonly found in sub-polar and alpine climates where they pose a considerable threat to society and nature. While the relationship between ROS frequency and large-scale climate features ... -
Carbon cycle feedbacks in an idealized simulation and a scenario simulation of negative emissions in CMIP6 Earth system models
Asaadi, Ali; Schwinger, Jörg; Lee, Hanna; Tjiputra, Jerry; Arora, Vivek K.; Séférian, Roland; Liddicoat, Spencer; Hajima, Tomohiro; Santana-Falcòn, Yeray; Jones, Chris D. (Peer reviewed; Journal article, 2024)Limiting global warming to well below 2 ∘C by the end of the century is an ambitious target that requires immediate and unprecedented emission reductions. In the absence of sufficient near-term mitigation, this target will ... -
Consequences of permafrost degradation for Arctic infrastructure - Bridging the model gap between regional and engineering scales
Schneider Von Deimling, Thomas; Lee, Hanna; Ingeman-Nielsen, Thomas; Westermann, Sebastian; Romanovsky, Vladimir; Lamoureux, Scott; Walker, Donald A.; Chadburn, Sarah E.; Trochim, Erin; Cai, Lei; Nitzbon, Jan; Jacobi, Stephan; Langer, Moritz (Journal article; Peer reviewed, 2021)Infrastructure built on perennially frozen ice-rich ground relies heavily on thermally stable subsurface conditions. Climate-warming-induced deepening of ground thaw puts such infrastructure at risk of failure. For better ... -
Emit now, mitigate later? Earth system reversibility under overshoots of different magnitudes and durations
Schwinger, Jörg; Asaadi, Ali; Steinert, Norman; Lee, Hanna (Peer reviewed; Journal article, 2022)Anthropogenic CO2 emissions cause irreversible climate change on centennial to millennial timescales, yet current mitigation efforts are insufficient to limit global warming to a level that is considered safe. Carbon dioxide ... -

Liu, Xiaozi; Tvinnereim, Endre; Grimsrud, Kristine; Lindhjem, Henrik; Velle, Liv Guri; Saure, Heidi Iren; Lee, Hanna (Peer reviewed; Journal article, 2021)We conducted a national survey on a high-quality internet panel to study landscape preferences in Norway, using photos as stimuli. We examined preference heterogeneity with respect to socio-demographic characteristics and ... -
