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.

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.

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.
