Wildfire smoke accelerates glacier melt, affects mountain runoff

As global temperatures rise, wildfires are becoming more common. A new study by University of Saskatchewan (USask) hydrology researchers found that exposure to wildfire smoke can cause glaciers to melt faster, affecting mountain ...

Olympic National Park's glaciers could be gone by 2070

By 2070, the glaciers on the Olympic Peninsula in Washington State will have largely disappeared, according to a new study. The loss will alter the region's ecosystems and shrink a critical source of summer water for local ...

Glaciers a common thread throughout new UN climate report

Glaciers appear in many chapters and sections of the latest report from the Intergovernmental Panel on Climate Change (IPCC), titled the Working Group II report of the IPCC's Sixth Assessment. Released on 28 February, it ...

'Blue blob' near Iceland could slow glacial melting

A region of cooling water in the North Atlantic Ocean near Iceland, nicknamed the "Blue blob," has likely slowed the melting of the island's glaciers since 2011 and may continue to stymie ice loss until about 2050, according ...

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 ...

Glacier

A glacier is a large mass of ice moving slowly over some land surface or down a valley, formed over long periods from the accumulation of snow in areas where the amount of snow that falls exceeds the amount that melts. The word glacier comes from French via the Vulgar Latin glacia, and ultimately from Latin glacies meaning ice.

Glacier ice is the largest reservoir of fresh water on Earth, and second only to oceans as the largest reservoir of total water. Glaciers cover vast areas of the polar regions and are found in mountain ranges of every continent except Australia, as well as in New Zealand. In the tropics glaciers are restricted to the highest mountains. The processes and landforms caused by glaciers and related to them are referred to as glacial. The process of glacier growth and establishment is called glaciation. Glaciers are sensitive monitors of climate conditions and are crucial to both world water resources and sea level variation.
