There are 100k glaciers and lakes tracked on that site. From what I can tell this is just a catalog. There seems to be no active data nor any kind of threat assessment. How can you conclude that this catalog makes this disaster avoidable?
1. getting the world on reducing carbon dioxide at least from the 70s on worldwide. This also could have saved some lives in the middle east.
2. Use the list as an start for monitoring the glaciers and alerting the people for evacuation with an regular test of all alarming systems, but this also would have taken years to implement.
I think #1 requires a LOT more nuance than carbon levels.
This was launched a week before the Nepal floods.
