The latest issue of the open access journal Mountain Research and Development is now available online – and contains two articles related to the MRI co-led GEO Global Network for Observations and Information in Mountain Environments (GEO-GNOME) initiative!
The latest issue of Mountain Research and Development (MRD) asks the question, 'what makes a mountain a mountain?' Answers to this question are complex, and have significant implications. As Roger Sayre and his co-authors – MRI Executive Director Carolina Adler among them – write in this issue of MRD, "knowing exactly where mountain ecosystems are distributed on the planet is a precursor to conserving them."
An estimated three-quarters of the water used by farms, ranches, and dairies in California originates as snow in the Sierra Nevada mountain range, but the future viability of that resource is projected to be at heightened risk due to global climate change.
In a study published in Proceedings of the National Academy of Sciences, University of California, Irvine (UCI) researchers argue that a 1.0 degree Celsius increase in the global average winter temperature will lead to a 20 percent jump in the likelihood of below-average snow accumulation in the high country, resulting in lower spring runoff. In this article, the authors describe how snow water equivalent, an important measure of water availability, and the elevation of the snowpack respond to different levels of warming.
