Mountain glaciers being dynamically unstable systems reveal rapid reaction on climate change. Glacier recession implies the landscape changes in the glacial zone, origin of new lakes and activation of natural disaster processes, catastrophic mudflows, ice avalanches, outburst floods, and etc. The presence of glaciers in itself threats to human life, economic activity and growing infrastructure. Economical and recreational human activity in mountain regions requires relevant information on snow and ice objects. Absence or inadequacy of such information results in financial and human losses. One of the urgent aims is to study the current trends in development of mountain glaciation of the Earth in conditions of global climate warming. The unbiased assessment of current and future development of glaciers requires effective system of monitoring including in-situ and remotely sensed studies. In the paper we give an overview of recent results on mountain glacier changes on the territory of Russia received both by surface measurements and remote sensing observation
