Dangers of this expedition

ENG: So, what are all these little problems and dangers that I'll face during these both trips ? Regardless of the season here's an idea:

• Storms : rain, snow, sand.
• Cold: freezing temperatures with . Add the windchill...
• Flash flooding: crossing rivers or quick melting of a glacier
• Sun: in the summer if I'm close to icecaps in nice weather without sunglasses, there's a risk of becoming snowblind. Something that already happened to me in New Zealand in 2004.
• Ice and crevasses, I will normally not be on the glaciers to avoid this risk
• Deep snow = slow and cold
• Not enough food, not enough fuel=not enough water
• Failure of fuel/gas stove = no water, no food.
• Fire in the tent.
• Whiteouts and "blackouts" = no visibility
• Battery failure, dead batteries = no electricity for GPS or Sattelite Phone.
• Avalanches
• Volcano eruption, earthquake: I hope not otherwise I'm pretty F***ed
• [more to come]
