CloudTracker Tracking Polluted Clouds: the Plausibility of a Strong Aerosol Cooling Effect on Earth’s Climate

Coordinator: TARTU ULIKOOL (EE)

Anthropogenic climate change is a tug-of-war with fossil fuels playing both sides of the field. Fossil fuel use emits both climate-warming greenhouse gases and climate-cooling aerosols. And aerosol impacts on clouds might have thus far masked a large fraction of greenhouse gas warming. If the aerosol cooling is strong, it implies 1) that the Earth’s climate is more sensitive to anthropogenic greenhouse gases than currently thought, and 2) reduced aerosol pollution has brought forward global warming. This project’s overarching hypothesis is that aerosol cooling is strong. I tackle this main hy…

About Horizon Europe (2021–2027)

Horizon Europe is the EU's current research and innovation programme, covering 2021 to 2027 with a budget of roughly €95.5 billion. Its three pillars are Excellent Science (frontier research and mobility), Global Challenges and European Industrial Competitiveness (mission-driven collaborative projects in health, climate, digital, security and food) and Innovative Europe (the EIC and EIT). It also funds five EU Missions targeting cancer, climate adaptation, smart cities, oceans and soils.

EU contribution: €2.0M awarded to the consortium. The project runs over approximately 5 years from 2026-05-01 to 2031-04-30.
