Multi-century dynamics of the climate and carbon cycle under both high and net negative emissions scenarios
(Peer reviewed; Journal article, 2022)Future climate projections from Earth system models (ESMs) typically focus on the timescale of this century. We use a set of five ESMs and one Earth system model of intermediate complexity (EMIC) to explore the dynamics ... -
The Multi-Decadal Response to Net Zero CO<inf>2</inf> Emissions and Implications for Emissions Policy
(Peer reviewed; Journal article, 2022)How confident are we that CO2 emissions must reach net zero or below to halt CO2-induced warming? The IPCC's sixth assessment report concluded that “limiting human-induced global warming to a specific level requires … ... -
A multi-model analysis of long-term emissions and warming implications of current mitigation efforts
(Journal article; Peer reviewed, 2021)Most of the integrated assessment modelling literature focuses on cost-effective pathways towards given temperature goals. Conversely, using seven diverse integrated assessment models, we project global energy CO2 emissions ... -
A multi-model assessment of the Global Warming Potential of hydrogen
(Peer reviewed; Journal article, 2023)With increasing global interest in molecular hydrogen to replace fossil fuels, more attention is being paid to potential leakages of hydrogen into the atmosphere and its environmental consequences. Hydrogen is not directly ... -
Multi-model simulations of aerosol and ozone radiative forcing due to anthropogenic emission changes during the period 1990-2015
(Peer reviewed; Journal article, 2017)Over the past few decades, the geographical distribution of emissions of substances that alter the atmospheric energy balance has changed due to economic growth and air pollution regulations. Here, we show the resulting ... -
A multimodel analysis of post-Glasgow climate targets and feasibility challenges
(Peer reviewed; Journal article, 2023)The COP26 Glasgow process resulted in many countries strengthening their 2030 emissions reduction targets and announcing net-zero pledges for 2050–2070 but it is not clear how this would impact future warming. Here, we use ... -

Nasjonal klimapolitikk i lys av Kyoto-protokollen
(1998:12, Working paper, 1998)Artikkelen drøfter valg og dosering av klimapolitiske tiltak på den nasjonale arena i et land som er bundet av en utslippsforpliktelse i Kyoto-protokollen. Den vanlige antakelsen om at en klimagassavgift skal være lik ... -
Nasjonale drivkrefter i USAs klimapolitikk
(Peer reviewed; Journal article, 2014)Da Obama overtok som president i 2009, var ett av hovedmålene å styrke amerikansk klimapolitikk. Fem år senere er målet fortsatt ikke blitt realisert. For å forklare denne manglende måloppnåelsen undersøker vi tre forhold: ... -

National Climate Policy Ambitiousness: A Comparative Study of Denmark, France,Germany, Norway, Sweden and the UK
(2013:02, Research report, 2013)This report explores how and to what extent the climate policies of Denmark, France, Germany, Norway, Sweden and the UK can be called ‘ambitious’. Relevant EU climate policies are also presented. The report develops three ... -
National climate policy, firm survival, and investments
(2000:08, Working paper, 2000)In this paper we consider how to design a national tradable quota system to reduce emissions of climate gases when the regulator is concerned about the survival of specific firms. The problem is studied using a two-period ... -
National contributions to climate change due to historical emissions of carbon dioxide, methane, and nitrous oxide since 1850
(Peer reviewed; Journal article, 2023)Anthropogenic emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) have made significant contributions to global warming since the pre-industrial period and are therefore targeted in international climate ... -
National specialization policy versus farmers’ priorities: Balancing subsistence farming and cash cropping in Nepal
(Journal article; Peer reviewed, 2021)The Nepali Government is currently implementing policies for a radical agricultural transformation into large-scale, mechanized, specialized and commercial farming. However, the peasants prioritize diversified subsistence ... -
Natural short-lived halogens exert an indirect cooling effect on climate
(Peer reviewed; Journal article, 2023)Observational evidence shows the ubiquitous presence of ocean-emitted short-lived halogens in the global atmosphere1,2,3. Natural emissions of these chemical compounds have been anthropogenically amplified since pre-industrial ... -
Near- and long-term global warming of current emissions
(2018:15, Research report, 2018-11-05)Human activities influence the climate in a range of ways. While emissions of CO2 from burning of fossil fuels is the dominant factor behind the present rapid global warming, many other gases and particles also contribute. ... -
Neglected implications of land-use and land-cover changes on the climate-health nexus
(Peer reviewed; Journal article, 2023)Climate change can substantially affect temperature-related mortality and morbidity, especially under high greenhouse gas emission pathways. Achieving the Paris Agreement goals require not only drastic reductions in fossil ... -
Net Zero: Science, Origins, and Implications
(Peer reviewed; Journal article, 2022)This review explains the science behind the drive for global net zero emissions and why this is needed to halt the ongoing rise in global temperatures. We document how the concept of net zero carbon dioxide (CO2) emissions ... -
A new halocarbon absorption model based on HITRAN cross-section data and new estimates of halocarbon instantaneous clear-sky radiative forcing
(Peer reviewed; Journal article, 2022)The article describes a new practical model for the infrared absorption of chlorofluorocarbons and other gases with dense spectra, based on high-resolution transmission molecular absorption database (HITRAN) absorption ... -
