Salt left on sublimating sea ice could have reflected 93% of sunlight, helping an already frozen Earth become even colder.

Pure water freezes only at around -38°C (-36°F). Tiny mineral dust particles act as so-called ice nucleators—crystallization ...

Nanoscale imaging shows ice can form across flat microcline surfaces without relying only on cracks or step edges.

Previously, a 2015 study of Antarctic sea ice observed salt crystallizing in cold, windswept ice and found its reflectivity increased as temperatures dropped. And in a 2016 study of simulated Snowball ...

Bengaluru witnessed a striking 22-degree sun halo around noon, with a bright ring appearing around the sun. The optical ...

Earth may have been pushed deeper into a global deep freeze by something surprisingly ordinary: salt. Around 700 million years ago, Earth entered periods of extreme glaciation known as Snowball Earth, ...

A prismatic halo surrounds the midday sun above Downtown Santa Cruz. According to the National Weather Service website, Earth ...

The better question isn’t if you can, but if you should.

Metro Detroit power outages have left many wondering about food in refrigerators and freezers. Here's what to toss and what ...

Ever wonder why the ice at your favorite cocktail bar looks like glass, while the cubes from your freezer look like tiny frozen clouds? It’s not magic; it’s a little bit of temperature science. When a ...
