Marianne is a climate scientist with PhD in meteorology and broad expertise in global atmospheric and climate modeling.
Experienced science disseminator. Studying the composition of the atmosphere and the climate response to emissions from human activities, with research spanning from detailed processes to overarching questions of human-induced climate change with implications for policymaking and society. Specific topics include the climate impact of aviation, emission metrics, short-lived climate forcers, emissions of air pollution in Asia and other regions, and interactions between the land surface, atmosphere, and climate.
PhD (2014), Department of Geosciences, University of Oslo. Title: "Climate impacts of past, present and future emissions from the transport sector".
M.Sc (2008), Meteorology and Oceanography, Department of Geosciences, University of Oslo
Steering committee member of PACES (Pollution in the Arctic: Climate, Environment and Societies)
Board member of NOSA (Nordic Society for Aerosol Research)
Risk of more fire weather in the North
There is an increasing risk of large wildfires in high latitude regions, Scandinavia included, concludes a newly published study by researchers from CICERO Center for International Climate Research and the University of Oslo.

Take climate-changing aerosols seriously
The dangerous impacts of aerosol changes on vulnerable regions should have been a priority at COP27 after climate policymakers agreed a breakthrough deal to support these parts of the world, scientists have claimed.

The more droughts, the more forest fires
Hot summers with more heatwaves and prolonged droughts can mean more forest fires. CICERO researchers are now looking at the risks and impacts of forest fires.

Global warming on a steady course
In a recent study published in Nature Communications, international scientists have taken on a persistent problem in climate science: near-term climate evolution.

Aviation contributes 3.5% to the human-made drivers of climate change, a new study shows
Aviation accounts for 3.5% of the human-made climate impact. Two-thirds of this impact are caused by emissions other than co₂, a new study shows.

ARIDITY - The role of anthropogenic dust in the present and future climate system
Dust is the most abundant species of aerosol in the atmosphere. While mineral dust from deserts is the largest source, an important but less well-studied component is soil dust from sparsely vegetated surfaces. Commonly referred to as “anthropogenic dust”, arising from the influence of human activities on land surfaces and subsequent increase in wind erosion and dust emissions, this source is believed to contribute a substantial fraction to the total global dust load. However, the contribution and climate impact of anthropogenic dust, through interactions with radiation, clouds and precipitation, is poorly quantified.

CATHY - Climate implications of rapid changes in Asian Anthropogenic Aerosol emissions
Emissions of Asian Anthropogenic Aerosols (A3) are rapidly changing - most notably black carbon and sulphate aerosol precursors from India and China. The resulting range of climate impacts and societal hazards may dominate regionally over greenhouse gas induced trends for the next several decades, but the implications are as yet insufficiently explored. CATHY (Climate implications of rapid changes in Asian Anthropogenic Aerosol emissions: Temperature, Hydrological cycle and variabilitY) tackles the urgent need for quantifying climate related hazards resulting from ongoing and projected changes in A3 emissions.

ENBEL: Connecting health and climate change research
Climate change is according to the WHO the greatest threat to human health in the 21st century. By bringing together leaders in climate change and health research the CICERO-coordinated Horizon 2020 project ENBEL will contribute with knowledge and policy advice on climate change and health links.

AVIATE: How can aviation contribute to a low-carbon society?
The AVIATE (Aviation in a low-carbon society) project will provide better understanding of the climate impact of aviation, both for Norway and globally, and explore options for reducing that impact.

Quantifying Climate Impacts of Future Forest Management Strategies in Norway
The international community has agreed that the increase in global temperature must be limited to 2°C above the pre-industrial levels. Meeting this ambitious goal requires a large-scale shift away from the fossil economy towards one based on renewable materials and energy like biomass.
