This year will conclude as the second hottest on record, surpassed only by 2024.

In the aftermath of historically severe wildfires in 2020, a study of Cascade Range watersheds found that stream vertebrates are doing surprising well, highlighted by flourishing fish populations.

A new study co-led by the University of Oxford has found that global aviation emissions could be reduced by 50-75% through combining three strategies to boost efficiency: flying only the most fuel-efficient aircraft, switching to all-economy layouts, and increasing passenger loads. Crucially, the study shows that around a 11% reduction in global aviation emissions is achievable immediately, by using the most efficient aircraft that airlines already have more strategically on routes they already fly.

Climate change, trust in science and health were among the most popular topics covered by UZH media releases and articles in 2025. 

UC Santa Cruz researchers show how vessel-tracking data mirrored tuna roaming beyond their typical territory due to unusually warm ocean temperatures.

As these events become more common at midlatitudes, a phenomenon called an atmospheric inversion will determine how long they last.

Businesses along the Norwegian coastline are becoming increasingly vulnerable to storm surges and flooding. 

A large Chinese research team has developed an air quality model called EPICC (Emission and atmospheric Processes Integrated and Coupled Community Model) that demonstrates improved accuracy in its representations of ozone and particulate matter with a diameter of 2.5 micrometers or less. 

The UC San Diego-led program joins forces with research programs across the world to improve forecasts of extreme weather events.

Research involving scientists from the University of Plymouth has shed new light on natural processes in East Antarctica that could, over long timescales, help the Southern Ocean absorb more carbon dioxide from the atmosphere.
