Period of warming is registered at Khibiny Mountains in the end of XX century. Sensible rise in temperature occur in winter. The one of general indicators of present climate changes is multiyear dynamic of nival processes not only for contrast high-mountain conditions but also for more temperate green belt. Compatible variability of both data sets from high-mountain (1050 m) and green belt (320 m) stations allows to full appreciation of present changes. The results of data evaluation shows stability of snow cover characteristics against changing of winter temperature conditions and avalanche activity.
