Key Points

• Glacier retreat is feeding a growing "last chance" tourism market at heavily visited ice sites.
• Tourism around glaciers creates a clear tension between local income and added emissions, waste, and physical disturbance.
• Glacier meltwater remains important for rivers and aquifers, so retreat carries direct water-security consequences far beyond tourism.
• Ice caves and similar glacier features are increasingly unstable, especially in warm seasons when meltwater raises collapse and flooding risk.
• The Iceland example shows how commercial demand can outrun safety guidance and push operations beyond scientifically supported limits.
• Governance responses are emerging, including shared safety portals and calls for tighter regulation, but the material suggests implementation still lags risk.
• The topic is coherent and structurally climate-linked rather than episodic: glacier loss, tourism pressure, and adaptation governance recur across the material.
