Ice in motion: Satellites view decades of change
New time-lapse videos of Earth's glaciers and ice sheets as seen from space—some spanning nearly 50 years—are providing scientists with new insights into how the planet's frozen regions are changing.

Heat from the landmass beneath the Antarctic ice sheet is a major contributor to the way that glaciers melt and flow—and their impact on potential sea level rise. Hotter conditions allow meltwater to lubricate the base ...

Can water reach minus 263 degrees Celsius without turning into ice? Yes it can, say researchers from ETH Zurich and the University of Zurich, if it is confined in nanometre-scale lipid channels.

Thwaites Glacier on the edge of West Antarctica is one of the planet's fastest-moving glaciers. Research shows that it is sliding unstoppably into the ocean, mainly due to warmer seawater lapping at its underside.

A volcano on Mars half the size of France spewed so much lava 3.5 billion years ago that the weight displaced the Red Planet's outer layers, according to a study released Wednesday.

Planetary scientists would be thrilled if they could peel the Earth like an orange and look at what lies beneath the thin crust. We live on the planet's cold surface, but the Earth is a solid body and the surface is continually ...

A collection of fossilized owl pellets in Utah suggests that when the Earth went through a period of rapid warming about 13,000 years ago, the small mammal community was stable and resilient, even as individual species changed ...

The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. Consequently, ...
