Clouds May Lose Cooling Effect, Researcher Warns of Climate Impact

other · 2026-08-26

Clouds currently cover two-thirds of the Earth and play a crucial role in cooling the planet, but the Intergovernmental Panel on Climate Change (IPCC) identifies them as the greatest uncertainty in the climate system. Andreas Macke, director of the Leibniz Institute for Tropospheric Research (TROPOS), emphasizes that clouds are the most relevant factor for climate research. The scientific community is still debating how clouds will change in a warming world, and losing their cooling effect could accelerate global warming. Macke's comments were made in an interview with the German newspaper der Freitag, which published an article on the topic. The article highlights the urgent need to understand cloud behavior to predict future climate scenarios accurately.
