A study led by the EPFL suggests that shipping emissions influence climate-relevant cloud formation and may affect regional ...

Clouds need two essential ingredients to form, and both must be present simultaneously for the process to begin. There are two ingredients needed for clouds to form: water and nuclei. The first ...

Tiny particles bubbling up from melting Arctic sea ice play a key role in cloud formation, suggests new research. The discovery may explain why Arctic clouds behave differently — and lead to improved ...

Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how ...

Miriam Freedman (left), professor of chemistry at Penn State, and Heidi Busse, a graduate student at Penn State, studied the freezing activity of four different types of microplastics to see how they ...

Clouds form when water vapor — an invisible gas in the atmosphere — sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, ...

Marine cloud brightening (MCB) is a form of geoengineering in which salt water is fired into the clouds in order to increase their brightness and reflectivity. The method shows promise in helping to ...
