Microplastics Are Affecting Melt Rates Of Snow And Ice
Current measurements and instruments do not take into account the effect that microplastics have on snow and ice, potentially overestimating the role of black carbon.
Glaciers may seem remote from the concerns of most people in the world. Their location atop high mountains makes them distant from population centers. Yet they bring new insights at the present time, since they lie at the frontlines of climate change. The mountain communities who take steps to address changing water supplies and natural hazards provide lessons for others who seek new forms of adaptation, policy and advocacy. The researchers who integrate geoscience and ecology in the study of landscapes guide research in sustainability in other areas as well. And the sheer beauty and majesty of glaciers inspire Indigenous peoples, climbers, artists and others, showing the depth of human connection to the natural world. Each week, GlacierHub offers these stories and images, showing the relevance of the world’s high icy places for all humanity.

An upcoming installation at the Brooklyn Botanic Garden intertwines the sounds of glacial recession and tree growth to help visitors connect with the area’s history.
As melting glaciers alter ecosystems in and around Antarctica, scientists study how sea squirts react.
A popular way of portraying icebergs is inaccurate. Through a viral tweet, watercolors, and interactive websites, people are learning about how icebergs actually float in water.
As glaciers recede in the Italian Alps, a shift toward grasslands is threatening native herbs like Artemisia genipi, a key ingredient in the region’s traditional liqueurs.
A recent study shows how on Siachen Glacier, the impacts of high-altitude warfare are two-way. As India and Pakistan’s armies have harmed the glacier, Siachen’s brutal conditions have also constrained military operations.
Montana Senator Jon Tester has proposed a bill that would add 17 rivers to the Wild and Scenic Rivers Act.
A recent study examines the changes in the foreland of a melting Icelandic glacier. With ice gone, new plant life is springing up and changing a centuries-old ecosystem.
The triumphant tale of 10 Nepali mountaineers’ pioneering winter ascent of the second highest mountain in the world stands apart from historic mountaineering narratives dominated by white men.
Ice is melting more rapidly than previously thought, according to two new studies, which examine some of the specific causes.
