CICERO

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

ARIDITY

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

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.

ChiNorBC

This project will help enhance the knowledge base for and support the development of a strategy for BC/OC co-control in China.

CICERO to study the climate impacts of hydrogen emissions

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.

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

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

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.
