China and Nepal have developed a close collaboration in glacier research. By sampling data on the north (Chinese) and south (Nepali) sides of the Himalayas, scientists from both countries can trace the movement of black carbon and heavy metals from South Asia across the mountains into the Tibetan Plateau, a topic of importance for water resources and for human health.
Greenland is a landscape dominated by ice. The Greenland Ice Sheet flows into terminal glaciers, which calve into icebergs, which in winter are locked in by sea ice. Ice shapes the entire food web, from ocean microbes to the fish that fuel 90 percent of Greenland’s GDP. The relationship between glaciers and Greenlandic fisheries just […]
A visit to a research station in the Qilian Mountains of western China brought the author to a glacier whose meltwater supplies oases along the Silk Road. Reflecting the region’s long history, the glacier has three names, one of them very surprising.
In September, a new report titled “Well Under 2 Degrees Celsius” was produced by the Committee to Prevent Extreme Climate Change, a global think-tank group made up of scientists, policy makers and military experts.
For the past 30 years, extensive conservation efforts have protected the Arctic National Wildlife Refuge from oil and gas interests. Now, the U.S. Department of the Interior (DOI) under the Trump administration has renewed a movement to open up the refuge to energy exploration. In a document obtained by the Washington Post on September 15, the […]
The residents of four Quechua villages in the Chicón valley in highland Peru performed a complex ritual on August 6 this year, as they have done for years, as a means of making offerings to Pachamama, the earth mother, understood as the source of vitality for humans and other beings. Such offerings, made at this […]
A recent paper in the Journal of Latin American Geography, “The Patagonian Imaginary: Natural Resources and Global Capitalism at the Far End of the World,” analyzes the construction of southern Andean Patagonia as an “ecoregion,” a label that has come to dominate the representation of the glaciated territory of Chile and Argentina. Through this representation, resource […]
On 17 August, the Intergovernmental Panel on Climate Change (IPCC) announced the list of experts it has invited to work on a major document, the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). Hans Poertner, the co-chair of IPCC Working Group II, underscored the importance of this report. In a statement issued […]
The Trump administration reviews a 545-page draft report about the causes and impacts of global warming including the imminent threat of glacial retreat, which is part of the National Climate Assessment.
Trump Administration Disbands Climate Advisory Committee From Nature: “The advisory group’s charter expired on 20 August, and Trump administration officials informed members late last week that it would not be renewed. ‘It really makes me worried and deeply sad,’ says Richard Moss, a climate scientist at the University of Maryland in College Park and co-chair […]
Trump on Climate: Deny, Deny, Deny From HuffPost: “Perry went on to defend his and others’ denial of near-universally accepted climate science, suggesting that those who question the scientific community’s findings are more intelligent. Also in June, Interior Secretary Ryan Zinke said glaciers in Montana’s Glacier National Park started melting ‘right after the end of […]
In the Arctic, global climate change is a story of disappearing ice. Midwinter sea ice has decreased by two million square kilometers since satellite records began 40 years ago, and glaciers in the Arctic have been melting at unparalleled speeds, profoundly impacting Arctic species and ecosystems. When it comes to activism about this troubling issue, […]
