CICERO

Hydrogen is often considered a green energy carrier that has the potential to replace oil, but little is known about its environmental and climate impacts. Over the next three years, CICERO will therefore study what these impacts are.

Rising use of nitrogen fertilisers could jeopardise global climate goals

The growing use of nitrogen fertilisers in world food production could put ambitious climate targets out of reach, as it leads to rising levels of nitrous oxide (N2O) in the atmosphere, a new study shows.

New study shows global temperature responds slowly to emissions cuts

Although large emissions cuts are urgently needed if we are to achieve the global climate goals, it may take decades before we can measure the effect of the reductions on global temperature evolution, a new study shows.

Key Earth System Processes to understand Arctic Climate Warming (KeyClim)

The objective of the KeyCLIM project is to develop The Norwegian Earth System Model (NorESM) to assess performance, develop and evaluate physical processes in the modell. A special effort is addressed to the near and long term future climate for the Artic, northern latitudes and Norway. Open data from the project will be provided to the climate mitigation and climate impact community.

4C – Climate-Carbon Interactions in the Current Century

The EU-funded project 4C (Climate-Carbon Interactions in the Current Century) aims to fill the knowledge gap surrounding climate sensitivity to carbon dioxide emissions by reducing the uncertainty in our quantitative understanding of carbon-climate interactions and feedbacks.

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.

SUPER - SUb-daily Precipitation Extremes in highly-populated Regions

The main objective of SUPER is to quantify the influence of anthropogenic activity on sub-daily extreme precipitation in highly populated regions

ICOS-Norge

Integrated Carbon Observation System (ICOS)-Norway and Ocean Thematic Centre (OTC)

Quantifying Impacts of South Asian Aerosols on Regional and Arctic Climate

The main objective of QUISARC is to quantify regional and Arctic climate impacts of South Asian aerosol emissions, by updating present emission inventories and tracing the aerosol impacts through teleconnections, and physical and chemical processes

Bio4Clim

Comparative climate impact assessment of the forest based bio-economies of Norway, Sweden and Finland

HYPRE - HYdropower and PREcipitation trends

Investigating historical and future precipitation trends in regions important for hydropower production

BlackArc (Black carbon and Arctic climate)

How do Black Carbon (BC) aerosols influence Arctic climate change? The outcome of the ‘BlackArc’ project is to reduce the uncertainty in modelling BC and to better constrain the climate impact of BC with an Arctic focus.

NAPEX

Precipitation is arguably the most direct link between the climate and human society. We depend upon existing precipitation patterns for fresh water and food production, and global infrastructure is designed to withstand current precipitation extremes.

CiXPAG - Interaction of Climate Extremes, Air Pollution and Agro-ecosystems

Future food production, and consequently food security, is very sensitive to both climate change and air pollution. So far, little is known about how climate extremes and ozone pollution interact to affect agriculture or about the relative effectiveness of climate change adaptation and ozone regulation measures for various crops and regions.

ACCRI CIC-MOD

The objective of the ACCRI CIC-MOD project is to investigate how aviation emissions in different regions affect the atmosphere and climate on regional and global scales.
