Climate Change

In the last two decades, Climate Change, both regional and global, has been an ongoing and often controversial topic in public debate and media. Nevertheless, it is widely acknowledged to have a profound effect on our world’s biosphere, atmosphere and hydrosphere. This is illustrated by findings of, e.g., extreme temperature fluctuations, flooding, droughts and receding glaciers.

Mountain regions as climate-limited environments are known to be especially sensitive to Climate Change, i.e. to temperature and precipitation. For example, the higher elevations of the Northern Rocky Mountains (North America) have experienced three times the global average temperature increase over the past century (Lina Barrera, Portraits of Climate Change: The Rocky Mountains). Such changes might affect extension of glaciers, snow melting time and distribution of runoff, availability of freshwater for natural systems and human uses, such as agriculture and food production. Changes in stream flow and higher water temperatures also could affect insects and other invertebrates that live in streams and rivers, with repercussions up the food chain. Possible consequences are changes in diversity and habitat range of high-elevation plant and animal species and shifting species communities.

Although research has gained much success within the last few years in the understanding of mountainous climate, it is still limited due to the complex geographical structure of mountain regions. The research scope of the MICMoR Research School is to understand the mechanisms and interactions of Climate Change in mountain regions by following an integrative approach through research at the interfaces of atmosphere- biosphere- pedo-/hydrosphere processes. 

While the scope of Climate Change research in the past tended to be strongly specialised, focusing on a single Earth-System compartment (e.g. atmosphere, biosphere or pedo-/hydrosphere), it is now well recognised that essential exchanges and interactions occur across interfaces and involve physical, chemical and biological processes over a wide range of spatial and temporal scales. An integrative approach of multi-disciplinary research collaboration is required to improve knowledge in this field of research and to bridge existing gaps in the understanding of environmental processes across scales and compartment boundaries.
