Threshold Effect of Economic Growth on Energy Intensity — Evidence from 21 Developed Countries
(Journal article; Peer reviewed, 2021)Based on threshold regression models, this paper analyzes the effect of economic growth on energy intensity by using panel data from 21 developed countries from 1996 to 2015. Results show that a 1% increase in GDP per ... -
The Time Scales of Climate Responses to Carbon Dioxide and Aerosols
(Peer reviewed; Journal article, 2023)The climate system responds to changes in the amount of atmospheric greenhouse gases or aerosols through rapid processes, triggered within hours and days, and through slower processes, where the full response may only be ... -
Top ten European heatwaves since 1950 and their occurrence in the coming decades
(Journal article; Peer reviewed, 2015)The Russian heatwave in 2010 killed tens of thousands of people, and was by far the worst event in Europe since at least 1950, according to recent studies and a novel universal heatwave index capturing both the duration ... -
Top-down or bottom-up? Norwegian climate mitigation policy as a contested hybrid of policy approaches
(Journal article; Peer reviewed, 2022)It is widely accepted that the Paris Agreement implies a shift in global climate mitigation policy from a top-down approach focused on global distribution of emission cuts and international cost-effectiveness to a bottom-up ... -
The transformative potential of local-level planning and climate policies. Case studies from Norwegian municipalities
(Journal article; Peer reviewed, 2022)We analyse whether and how current municipal climate policies can be characterised as transformative and which factors and pathways may lead to transformative change at the municipal level. Based on 13 in-depth case studies ... -
Transforming knowledge systems for life on Earth: Visions of future systems and how to get there
(Journal article; Peer reviewed, 2020)Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of ... -
Transitions in pathways of human development and carbon emissions
(Peer reviewed; Journal article, 2014)Countries are known to follow diverse pathways of life expectancy and carbon emissions, but little is known about factors driving these dynamics. In this letter we estimate the cross-sectional economic, demographic and ... -
Trends in atmospheric methane concentrations since 1990 were driven and modified by anthropogenic emissions
(Peer reviewed; Journal article, 2023)The atmospheric methane trend is not fully understood. Here we investigate the role of the main sink, the main natural source, and anthropogenic emissions on the methane growth rate over the last three decades using numerical ... -
Tropospheric ozone changes, radiative forcing and attribution to emissions in the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP)
(Peer reviewed; Journal article, 2013)Ozone (O3) from 17 atmospheric chemistry models taking part in the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) has been used to calculate tropospheric ozone radiative forcings (RFs). All models ... -
Troublesome leisure travel: Counterproductive sustainable transport policies
(Chapter, 2015)In this chapter, we present three well-established sustainable transport policies – developing more compact cities, building pro-environment awareness and attitudes, and promoting growth of information and communication ... -
Troublesome Leisure Travel: The Contradictions of Three Sustainable Transport Policies
(Peer reviewed; Journal article, 2011)Sustainable passenger transport policies are most often directed towards everyday travel and ignore the large and expanding amount of leisure travel. The paper examines whether policies aimed at reducing energy consumption ... -
Troublesome Leisure Travel: The Contradictions of Three Sustainable Transport Policies
(Peer reviewed; Journal article, 2011)Sustainable passenger transport policies are most often directed towards everyday travel and ignore the large and expanding amount of leisure travel. The paper examines whether policies aimed at reducing energy consumption ... -
Uncertain Climate Policy Decisions and Investment Timing: Evidence from Small Hydropower Plants

Uncertainties around reductions in China's coal use and CO 2 emissions
(Peer reviewed; Journal article, 2016)Chinese coal consumption dropped 2.9% in 2014 according to preliminary official statistics1 released in 2015. This was hailed as historic after China’s meteoric growth in the 2000s2. The International Energy Agency used ... -
Uncertainty in land carbon budget simulated by terrestrial biosphere models: the role of atmospheric forcing
(Peer reviewed; Journal article, 2022)Global estimates of the land carbon sink are often based on simulations by terrestrial biosphere models (TBMs). The use of a large number of models that differ in their underlying hypotheses, structure and parameters is ... -
Under what conditions will the paris process produce a cycle of increasing ambition sufficient to reach the 2°c goal?
(Journal article; Peer reviewed, 2020)The Paris Agreement establishes a cycle where parties submit their nationally determined contributions (NDCs) every five years. First-round NDCs fail to put emissions on a path consistent with achieving the Agreement’s 2°C ... -
Understanding and Managing Harmful Algal Bloom Risks in a Changing Climate: Lessons From the European CoCliME Project
(Journal article; Peer reviewed, 2021)This paper discusses the conceptual and methodological challenges to co-developing high-quality and transferable knowledge to understand and manage harmful algal bloom (HAB) risks as part of adaptation to changing aquatic ... -
Understanding low-carbon food consumption transformation through social practice theory: The case of community supported agriculture in Norway
(Journal article; Peer reviewed, 2022)Drawing on a qualitative case study of consumers involved in community-supported agriculture farms in Norway, this article applies social practice theory to understand pro-environmental behaviour transformation in relation ... -
Understanding model diversity in future precipitation projections for South America
(Journal article; Peer reviewed, 2021)Precipitation patterns are expected to change in the future climate, affecting humans through a number of factors. Global climate models (GCM) are our best tools for projecting large-scale changes in climate, but they ...
