Greenland’s glaciers have retreated so far that they can no longer support the ice sheet that feeds them. The ice sheet system has reached a new normal of consistent annual ice loss.

For the first time, scientists have been able to quantify how much climate change contributed to glacial melt, using more than 40 years of data from New Zealand’s retreating glaciers.

Auckland’s extreme drought and the rapid retreat of glaciers in the Southern Alps both highlight how important long-term observations are for water management policy and planning.
A glacial depositional feature – an erratic – is a large rock that has been ‘bull-dozed’ and deposited by a moving glacier.

These findings are in stark contrast with the original worldview that suggested the entire globe was at a maximum glaciated state around 20 000 years ago.
Glacier mice were first documented in 1951, but they continue to mystify scientists.

Meltwater lakes forming at the head of glaciers are causing them to shrink faster, which will affect the flow of big rivers that supply millions of people downstream in Asia.

Peruvian glaciers have shrunk by 25% since 1987, causing water shortages in rural villages. But ancient technology could help manage this precious resource.
A small boat in the Illulissat Icefjord is dwarfed by the icebergs that have calved from the floating tongue of Greenland’s largest glacier, Jacobshavn Isbrae.

Satellites hundreds of miles overheard are helping scientists to predict drought, track floods and see how climate change is changing access to water resources.

A new report predicts that one-third of the ice in the Himalayas will melt, even if we contain global warming to 1.5C. So what does that mean for the flood-prone valleys below?
The Quelccaya Glacier in Peru, which has major social and economic value, is disappearing along with other tropical glaciers.
