Observing Glaciers in 'Real Time'

Written by Markus Gross. Source: ETH ZurichHot summers cause glaciers to melt. That not only changes the makeup of the landscape and hence the maps of Switzerland, it also affects every area of society. A new, dynamic glacier inventory makes the impact of climate change and the changing landscape visible.[caption id="attachment_3695" align="alignright" width="300"] Glacier observation under the spell of several Valais four-thousand-metre peaks. (Image copyright: GLAMOS / ETHZ)The last time Swiss glaciers managed to grow at all was in 2001. Since then, the country’s 1,500 glaciers – as well as others elsewhere – have been suffering a slow but inexorable death. Until now, though, we have understood only partially how quickly they are really disappearing, and what effect that has on the landscape, people and animals. That is about to change, thanks to the Glacier Monitoring in Switzerland (GLAMOS) project. GLAMOS is working on behalf of various Swiss federal offices to...

MRI Synthesis Workshop on Treeline Spatial Patterns

Most mountain inhabitants and visitors will have clear mental images of the alpine treeline, the conspicuous transition from forest to treeless alpine vegetation. These images are likely to be as varied across the globe as the actual variation in form and landscape positions that can be observed between sites and mountain ranges. These spatial patterns can provide insights in what makes each treeline unique and in what makes some of them similar enough to allow generalised predictions about their dynamics. Pictured: Workshop participants visit a treeline site in the Pyrenees (here with a view on Ordesa y Monte Perdido National Park). Photo: Dave CairnsIn a recent workshop, held near the Pyrenees between 31 August and 5 September 2017, nine treeline researchers gathered to discuss how this global variation in spatial patterns at treelines from the subarctic to the tropics can be captured, quantified and used to predict dynamics at different treeline...
