Large Arctic wildfires have caused around 21,000 excess deaths each year between 2001 and 2020, of which roughly 8000 occurred in countries outside the Arctic Council, suggest Earth model simulations.

Despite stringent efforts to reduce greenhouse gas emissions, California is the largest emitter of sulfuryl fluoride in the USA, according to atmospheric measurements and an inverse model.

JWST collects vast amounts of information about exoplanets light years away from Earth. Back home, the measured optical constants of laboratory aerosols are critically input parameters in models to interpret the observational results.

Gebanruo Chen explains how tethered air balloons can take high-resolution and high-altitude water vapour measurements to give insights into the atmospheric water cycle

Air pollution is a leading cause of death globally. Efforts to clean the air will not only save lives but contribute to addressing broader environmental and socioeconomic challenges.

Africa’s worsening air pollution has received too little attention. We argue that actions are needed in energy transition management, transport emission regulation and waste management to protect Africa’s air quality.
