Certain communities of pond plants may increase greenhouse gases

Cornell University
Peer-Reviewed Publication

ITHACA, N.Y. - The composition of aquatic plant communities in shallow freshwater bodies, including floating plants, submerged plants and phytoplankton, can have important effects on greenhouse gas production, transport and emissions, according to a new study by Cornell University researchers.

Rising temperatures intensify "supercell thunderstorms" in Europe

University of Bern
Peer-Reviewed Publication

In a groundbreaking study, researchers from the University of Bern and ETH Zurich have shown how climate change is intensifying supercell thunderstorms in Europe. At a global temperature increase of 3 degrees Celsius, these powerful storms are expected to occur more frequently, especially in the Alpine region. This research utilizes a state-of-the-art digital map that provides unprecedented precision in tracking these storms.

Wind isn’t the only threat: USF-led scientists urge shift to more informed hurricane scale

University of South Florida
Peer-Reviewed Publication

A new paper published in Nature Scientific Reports finds that in order to keep people safe, the Saffir-Simpson Hurricane Wind Scale should be replaced with the Tropical Cyclone Severity Scale, which incorporates storm surge and rainfall in addition to wind.

Deep-learning model visualizes urban heat stress at the meter scale

Karlsruher Institut für Technologie (KIT)
Peer-Reviewed Publication

Cities are particularly vulnerable to heat stress because paved and densely built-up areas tend to store the heat. More frequent and intense heatwaves are a growing challenge for public health and urban infrastructure. A new deep-learning based model developed by the University of Freiburg and Karlsruhe Institute of Technology (KIT) calculates for the first time how heat stress will develop on each square meter of a city in the future. The model supports cities in their efforts to adapt to the climate change and provides stimuli for climate-friendly urban planning. Published in Urban Climate. (DOI: 10.1016/j.uclim.2025.102564)

Tropical volcanic eruptions push rainfall across the equator

Princeton University, Engineering School
Peer-Reviewed Publication

Major eruptions create distinct patterns of flooding depending on the location of the volcano and the dispersal of its plume. The patterns mostly divide along the line of the equator. When a volcano’s plume is generally contained in one hemisphere, flooding decreases in that hemisphere and increases in the other hemisphere. The pattern most strongly affects the tropical regions and demonstrates little to no effect on other regions.
