The Nepal incident is also messy because it's a extremely specific local/regional phenomenon, which was always a threat (and has happened before in other, less-populated areas around the Himalayas), but without consistent warming leading to glacier loss, it would be a random rare tragedy. Now that we know what happened and what causes it, we can pretty well expect that it will happen again... but there are so many similar hanging glacers high above steep V-shaped river valleys that we can't easily monitor or predict, not to mention alert locals and evacuate people in time. How many other similar local phenomena will appear? Impossible to say.
