ETH Zurich researchers conducted an experiment to investigate the initial steps in the formation of aerosols. Their findings are now aiding efforts to better understand and model that process - for example, the formation of clouds in the atmosphere.

The first COVID-19 lockdowns led to significant changes in urban air pollution levels around the world, but the changes were smaller than expected - a new study reveals.

Many of the most advanced climate models simulate smoke that is darker, or more light absorbing, than what researchers see in observations.

ASU School of Earth and Space Exploration scientist Amanda Clarke and her team have been working to solve the mysterious root cause of the Sunset Crater eruption and any lessons learned to better understand the threats similar volcanoes may pose around the world today. But as to why it erupted, that has remained a mystery, until now. Clarke's group is among the first to show the importance of carbon dioxide in volcanic eruptions.

A new study led by researchers at the Universities of Bristol, Exeter, and Bath helps to shed light on the winter weather we may soon have in store following a dramatic meteorological event currently unfolding high above the North Pole. Weather forecasting models are predicting with increasing confidence that a sudden stratospheric warming (SSW) event will take place today, 5 January 2021.

Although stellar flares are typically viewed as a detriment to habitability, study shows "life might still have a fighting chance." Researchers find that flares drive a planets atmospheric composition to a new chemical equilibrium.
