Roundup: Cryospheric Microbes, Moving Borders, and a Glacial Chase Movie

New Article Reports Current Knowledge on the Microbial Ecology of the Cryosphere

A report synthesizes our current knowledge of microbial ecosystems in cold (below 5 degrees Celcius) environments, including glacial habitats.

From Applied Microbiology and Biotechnology: “Microorganisms in cold ecosystems play a key ecological role in their natural habitats. Since these ecosystems are especially sensitive to climate changes, as indicated by the worldwide retreat of glaciers and ice sheets as well as permafrost thawing, an understanding of the role and potential of microbial life in these habitats has become crucial. Emerging technologies have added significantly to our knowledge of abundance, functional activity, and lifestyles of microbial communities in cold environments. The current knowledge of microbial ecology in glacial habitats and permafrost, the most studied habitats of the cryosphere, is reported in this review.”

A Moving Border: Alpine Cartographies of Climate Change

A new book explores how global warming poses a challenge to national borders.

From the Columbia University Press description: “Italy’s northern border follows the watershed that separates the drainage basins of Northern and Southern Europe. Running mostly at high altitudes, it crosses snowfields and perennial glaciers—all of which are now melting as a result of anthropogenic climate change. As the watershed shifts so does the border, contradicting its representations on official maps. Italy, Austria, and Switzerland have consequently introduced the novel legal concept of a “moving border,” one that acknowledges the volatility of geographical features once thought to be stable.”

Scandinavia House Screens 2017 Film Following World War II Fighter Through Norway’s Frozen Landscapes

From Scandinavia House: “Based on the true-life tale of World War II resistance fighter Jan Baalsrud, The 12th Man follows a Norwegian mission group’s journey across the North Sea to sabotage a German military facility. When the group’s identity is compromised and they’re attacked by a Nazi warship, Baalsrud is the sole member to evade capture, who escapes by swimming across frigid fjord waters to a nearby island to hide within the mountains.What follows is a harrowing exodus, as Baalsrud fights to stay alive in sub-freezing temperatures, surrounded by landscapes that are as stunningly beautiful as they are treacherous. In his quest for survival under relentless pursuit by a Nazi officer, Baalsrud must rely on the compassion of locals willing to risk their lives to help him cross the border to safety in Sweden.”
