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 ... -

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 ... -
Understanding Top-of-Atmosphere Flux Bias in the AeroCom Phase III Models: A Clear-Sky Perspective
(Journal article; Peer reviewed, 2021)Biases in aerosol optical depths (AOD) and land surface albedos in the AeroCom models are manifested in the top-of-atmosphere (TOA) clear-sky reflected shortwave (SW) fluxes. Biases in the SW fluxes from AeroCom models are ... -
United States participation in future climate agreements: An assessment
(CICERO Policy Note;2005:01, Working paper, 2005)The report identifies the major obstacles to U.S. participation in an international treaty to control greenhouse gas emissions, and suggests some possible strategies for reengaging the United States. It proceeds as follows: ... -
The United States: conditions for accelerating decarbonisation in a politically divided country
(Journal article; Peer reviewed, 2021)President Biden faces tremendous challenges to overcome political polarisation as he re-commits the United States to the Paris Agreement on Climate Change and promises decarbonisation of the US economy over the next three ... -
