Due to the steady changes in precipitation in recent years, a deeper than usual snow cover has formed in Northeast Siberia . This alters the capacity of reindeer to access lichen, their primary food source. Late onset of cold weather has led to difficulties in the herds moving to their winter pastures. In the summer, increased rainfall has led to waterlogging of low-lying pastures. The most important challenge is the instability of the weather . This includes frequent, never-before-seen warming, combined with rains in the late winter and early spring. Sharp temperature drops of over 30℃ occurring within a few hours lead to formation of an ice crust on the ground which becomes a challenge for reindeer, especially in autumn, and are becoming more frequent. Furthermore, the number of summer storms and rapid cooling accompanied with snowfall during July has increased. Using IK to predict weather is the basis of effective survival. It has become extremely difficult due to the unprecedented fast changing conditions  . All of these events lead to increased risks in the lives of Indigenous Peoples .
