Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope, essentially documenting the ...

"The nucleation of ice is really important for the atmospheric science community and climate modelling," said Davies. "At the moment there is no viable way to predict ice nucleation other than ...

By producing fewer and larger ice crystals, clouds that undergo heterogenous nucleation end up reflecting less solar radiation, but they also allow more radiation from Earth to escape into space.

Ice particles in the atmosphere influence clouds, precipitation and climate, and often form with help from aerosols that serve as ice-nucleating particles. Biological particles 1, including non ...

With governments and scientists trying to find tangible solutions to cool our planet and limit warming to a 1.5 C to 2 C temperature rise during this century, a new idea has been pitched to stop that ...

Even if solar geoengineering worked perfectly, it wouldn't solve all the problems associated with CO2 emissions, such as the acidification of the ocean caused by carbon build-up, Keutsch said.

A representational image of a plane that scientists would use to inject two tons of particles of ice 11 miles high each week, which would freeze the water that would fall back to Earth.

The team found that ash-rich volcanic eruptions caused clouds to host fewer, but larger ice crystals. “At the beginning of the study, we did expect clouds affected by volcanic eruptions to look ...
