Glaciers sizzle as they disappear into warmer water

Scientists have recorded and identified one of the most prominent sounds of a warming planet: the sizzle of glacier ice as it melts into the sea. The noise, caused by trapped air bubbles squirting out of the disappearing ...

Global sea level rise dampened by Australia floods

When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by the National Center for Atmospheric Research (NCAR) shows that when three atmospheric patterns came together over the Indian ...

Coastal Antarctic permafrost melting faster than expected

For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, ...

Melting ice pulls Norway closer to Asia

The town of Kirkenes in northernmost Norway used to be further away from Asia than virtually any other European port, but it suddenly seems a lot closer. The reason: Global warming.

Brittle material toughened: Tungsten-fibre-reinforced tungsten

Tungsten is particularly suitable as material for highly stressed parts of the vessel enclosing a hot fusion plasma, it being the metal with the highest melting point. A disadvantage, however, is its brittleness, which under ...

How the ice ages ended

A study of sediment cores collected from the deep ocean supports a new explanation for how glacier melting at the end of the ice ages led to the release of carbon dioxide from the ocean.
