Mountain glaciers may hold less ice than previously thought

Mountain glaciers are essential water sources for nearly a quarter of the global population. But figuring out just how much ice they hold—and how much water will be available as glaciers shrink in a warming world—has ...

Melting glaciers, as well as ice sheets, raising Earth's seas

As the planet's polar ice sheets destabilise amid rising temperatures, a landmark UN assessment of Earth's retreating frozen spaces is also set to spell out how melting mountain glaciers will impact humanity in the decades ...
