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.

Large uncertainty in warming outcomes of current policies and emission pledges

During the recent Glasgow Climate Conference (COP26) there was a lot of focus on the climate outcomes of new climate policy pledges. A new analysis shows that these outcomes are more uncertain then often assumed.

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.

ClimINVEST suite of scientific factsheets - building understanding

This suite of scientific factsheets aim to build financial decision-makers' understanding about physical climate risk assessment, data needs, climate modeling and extreme events.
