Watch: What caused the flash floods in the Nepal-Tibet border
At least 270 people have died in the massive flash floods, while more than 800 others are missing.
TL;DR
- Floods on the Nepal-Tibet border were caused by a 'glacial collapse'.
- Initial reports incorrectly suggested an earthquake was the cause.
- The cause of the glacial collapse itself is undetermined.
- Himalayan glaciers are melting faster due to rising temperatures and climate change, according to scientists.
