Scientists stunned: Volcano cleans up after itself by removing methane from the air

University of Copenhagen
Peer-Reviewed Publication

A violent volcanic eruption in the South Pacific has revealed a surprising natural mechanism that could potentially help slow global warming. The finding provides entirely new insights into atmospheric chemistry and may inspire new methods to remove methane emissions from the air.

Researchers reconstruct path and intensity of China's Guangzhou 'April 27' tornado using multi-source data

KeAi Communications Co., Ltd.
Peer-Reviewed Publication

A recent study has constructed a disaster picture of the "April 27" tornado that struck Guangzhou, China in 2024 by integrating Unmanned Aerial Vehicle (UAV) imagery, detailed ground-based post-disaster surveys, and high-precision meteorological simulations. The research analyzed the tornado's trajectory, intensity, and its impact on building structures, providing a reference for tornado disaster assessment and the wind-resistant design of engineering structures in South China.

Baltimore emergency rooms see spike in asthma-related cases after night heat waves

Johns Hopkins University
Peer-Reviewed Publication

Hospitals in Baltimore see an uptick in asthma-related emergency room cases in the weeks following nighttime heat waves in their neighboring communities. The findings suggest heat alert systems that rely on daytime temperature forecasts may need to be updated to be more helpful for people with asthma or other heat-sensitive health conditions.

On the ground or in the atmosphere? New satellite data can help characterize and pinpoint destructive events

European Geosciences Union
Reports and Proceedings

Solar storms can quietly disrupt satellites, power grids, and communication systems across the globe. After a 2022 geomagnetic event knocked out dozens of Starlink satellites, the risks are no longer hypothetical. At EGU26, scientists unveil Swarm-AWARE, a new ESA project using satellite data and machine learning to distinguish space weather signals from natural hazards, paving the way for smarter forecasting and more resilient infrastructure.

Atmospheric systems control the transport of rainfall and nutrient from Africa to the Amazon

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Study indicates that events such as cold air masses in the Northern Hemisphere alter the transport of aerosols across the Atlantic that nourish forest soils. It was previously believed that this influence came from changes in wind direction.

Sharks may help improve climate forecasts, study finds

University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science
Peer-Reviewed Publication

A new study published in the journal npj Climate and Atmospheric Science, shows that electronically tagged sharks can serve as mobile sensors, collecting ocean climate data in regions that are difficult to observe using conventional methods.

AI falls short in predicting weather extremes

Université de Genève
Peer-Reviewed Publication

Record-breaking heatwaves, torrential rainfall and supercell thunderstorms: extreme events are intensifying under the influence of climate change, with major human and economic consequences. Artificial intelligence models are revolutionizing weather forecasting. But can they anticipate such exceptional events? A team from the University of Geneva (UNIGE) and the Karlsruhe Institute of Technology (KIT) shows that, to date, traditional numerical models remain more reliable for predicting extreme phenomena, even though AI models outperform them under typical conditions. These findings are published in Science Advances.
