Natural Hazards & Mountaineering

High-Altitude Mountaineering and Natural Hazards

Despite increased comfort and improved safety, high-altitude expeditions are still a risky thing. Given the ongoing and intensifying climate change, high mountains are particularly prone to changes in the climate regime, e.g. the wind and precipitation patterns. How do these climate patterns change? Do potential changes affect high-altitude mountaineering via changes in the Natural Hazard portfolio, e.g. snow storm intensity, wind storms or avalanche frequency? As a passionate climber and mountaineer, I try to find answers for such questions (also see under Opportunities).
