The Earth’s atmosphere is a complex and dynamic envelope comprised primarily of nitrogen and oxygen, with trace gases such as carbon dioxide, methane, water vapour and ozone playing outsized roles in ...

Atmospheric methane rose faster than ever in the early 2020s, driven less by fossil fuels and more by changes in nature itself.

Criegee intermediates are transient carbonyl oxide species generated during the ozonolysis of alkenes, and they play a pivotal role in atmospheric oxidation processes. Their formation initiates a ...

Nitrates in the atmosphere reduce air quality and play an important role in climate change. An international team led by Hokkaido University researchers has revealed how chemical processes in the ...

The Dibble group investigates chemistry of the atmosphere, combustion, and irradiation, focusing on atmospheric chemistry. A current focus is atmospheric mercury, but we have long been involved in ...

FRANKFURT/MAINZ/HELSINKI/LEIPZIG. Who hasn’t enjoyed the aromatic scent in the air when walking through the woods on a summer’s day? Partly responsible for this ...

Which human activities are changing our climate, and does climate change constitute a major problem? We will investigate these questions through an introduction to climate processes and an exploration ...

A temporary weakening of the atmosphere's chemical capacity to break down methane, combined with elevated emissions from tropical wetlands, drove the ...
