Increasing ocean temperature threatens Greenland’s ice sheet — ScienceDaily

Scientists at the University of California, Irvine and NASA’s Jet Propulsion Laboratory have for the first time quantified how warming coastal waters are impacting individual glaciers in Greenland’s fjords. Their work is the subject of a study published recently in Science Advances. Working under the auspices of the Oceans Melting Greenland mission for the past […]

Global ice loss increases at record rate

And the findings also reveal that the Earth lost 28 trillion tonnes of ice between 1994 and 2017 – equivalent to a sheet of ice 100 metres […]

Pluto’s haze made up of ice crystals with cyanide hearts

The haze shrouding Pluto might be made up of ice crystals possessing cyanide hearts, a new study finds. Hazes, which are made of tiny motes of dust, smoke, ice and other substances, are not unique to Earth — scientists have detected hazes enveloping Mars, Venus, Saturn and Jupiter.  Nor are hazes limited to planets. Saturn’s […]

The Catcher in the Ice

A new device used to extract gas trapped in ice cores by sublimation will shave hours off the time needed by previous versions of the technology. It will use a light source with a more suitable wavelength, which will rotate around the ice sample. “Ice cores contain actual samples of the past atmosphere,” said Michael […]

Ice covers the Sahara Desert for just 4th time in 50 years

On Tuesday (Jan. 19), one of the world’s driest places awoke to an otherworldly dusting of frost. In the Sahara Desert of northwestern Algeria, just outside the town of Ain Sefra, sand dunes were streaked with ice crystals as far as the eye could see. Local photographer Karim Bouchetata captured the unusual weather in pictures […]

Dire wolves are actually ice age mega-foxes

The giant predators weren’t closely related to today’s canines, even if they look quite a lot alike. (MAURICIO ANTÓN/) When you picture a dire wolf, the image that comes to mind is probably one of those unbelievably fluffy yet terrifying creatures that inhabited Winterfell in Game of Thrones. And you’d hardly be the only one, […]

Juno Maps Water Ice Across Northern Ganymede

Jupiter’s moon Ganymede is the largest planetary satellite in the solar system. It’s also one of the most intriguing: Ganymede is the only moon with its own magnetic field, it is the most differentiated of all moons, and it likely possesses a subsurface ocean of liquid water. It was studied by the early […]

Hikers find ghostly ‘hair ice’ clinging to trees in an Irish forest

Hikers in Ireland were strolling among the frosty trees last week when they stumbled into what looked like an enchanted candy forest. White wisps of fluffy frost bloomed from tree branches like cotton candy, but the mysterious fluff disappeared with a single touch, the hikers tweeted. There’s no witchcraft afoot in the forest (and no, […]

Ice Age hunters’ leftovers may have fueled dog domestication

dog on a leash

Sometime between around 29,000 and 14,000 years ago, hunter-gatherers navigating northern Eurasia’s frigid landscapes turned wolves into dogs by feeding them lean-meat leftovers. That, at least, is a likely scenario that would have benefited both wolves and people, say archaeologist Maria Lahtinen of the Finnish Food Authority in Helsinki and colleagues. In harsh Ice Age […]
