For decades, the frozen Antarctic wilderness at the bottom of the world defied global warming trends, with ice levels actually growing – until 2015 when it suddenly reversed. Now scientists say they have discovered why.

The mysterious origin of an impressive cloud disturbance on Venus has now been revealed by a team including the University of Tokyo. Researchers used numerical models to show that an enormous 6,000-kilometer-wide atmospheric wave front, which circumnavigates the planet for days at a time, is caused by a large “hydraulic jump.” This is when a fluid abruptly slows down, changing from shallow and fast to deep and slow. On Venus, a sudden change in airflow in the lower cloud region is coupled with the creation of a strong updraft, forcing sulfuric acid vapor higher into the atmosphere where it condenses into a massive line of cloud. Future planetary studies can consider the potential impacts of this process, and what it might mean for any exploratory missions.   

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.

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.
