In August, a glacier collapse in Nepal triggered a catastrophic flood, and the danger still isn't over. Fragile new lakes have formed from the debris, and authorities are warning that another flood could burst through at any moment, putting rescuers still working in the area at risk. It's called a Glacier Lake Outburst Flood, and unlike most disasters, it doesn't really have an aftermath. The same lake can collapse again and again for years.
These floods are becoming more common as the climate warms. But there's also a rare bit of good news: a decade ago, Nepal's own army successfully defused a similar lake, flying equipment up a mountain to build a permanent drain. Alaska's capital Juneau has the same problem and the same fix on the table. It just hasn't built it.
