Claim:
Artificial intelligence will have a net positive impact on the climate.
SOME BS
Alps-wide records show 2025–26 avalanche fatalities near the ~100 long-term average.
Claim:
The number of avalanches in the Alps has increased significantly in 2026 compared to previous years, and this increase is attributed to climate change.
