Changes in Earth's tilt relative to the sun have governed the movements of giant ice sheets over the past 800,000 years, triggering the start and end of eight ice ages, new research suggests. The ...

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.

Researchers have developed a novel method to detect and study how ice forms in mixed-phase clouds, significantly boosting scientists' ability to forecast weather and model climate change.

Clouds are essential to regulating Earth’s climate and energy balance. They cover about 70 percent of the planet’s surface and play a key role in both reflecting sunlight and absorbing heat.

In clouds in the mid-to upper atmosphere where temperatures are between 32 and minus 36 F (0 to minus 38 C), ice crystals normally form around mineral dust particles from dry soils or biological ...

Other investigations have focused on the kinetics of atmospheric ice nucleation, providing advanced parameterisations that integrate classical and non‐classical nucleation pathways, thereby ...

Well, according to researchers, Earth ice is made up of orderly lattice crystal designs. These all showcase the six-fold symmetry of snowflakes in the underlying structure.

Specifically, they found that the end of any given ice age, the last of which was 11,700 years ago, is brought about by a combination of changes in precession of Earth's axis, which affects peak ...

Predictions of a link between Earth’s orbit of the sun and fluctuations between glacial and interglacial conditions have been around for over a century but were not confirmed by real-word data until ...

MIKE MOSS SAYS: Bill, Rings around the moon can be caused by ice crystals or by small water droplets in clouds that are shallow enough to allow the moon to be seen behind them, and the ring size ...

The extent of Antarctic sea ice dropped precipitously in 2023. Analysis shows that this decline has increased the transfer of ocean heat to the atmosphere — in turn affecting ocean circulation ...
