A rock and ice avalanche triggered a massive flood in Nepal's steep valley, killing thousands.

The incident is a stark example of the growing dangers posed by melting glaciers and thawing permafrost across the Himalayas. As these natural barriers weaken, the likelihood of catastrophic floods and landslides increases, threatening lives and infrastructure.

More people are moving into flood-prone areas in Nepal's Himalayan valleys, putting them at greater risk from extreme weather events.

The long-term outlook is grim as climate change continues to melt glaciers and thaw permafrost, exacerbating the risks of floods and landslides.

What is the long-term climate outlook for this region?

As temperatures rise, glacial lakes will expand and mountain permafrost will continue to thaw, increasing flood risks. The growing population in these areas means more lives are at stake, making it imperative for Nepal to develop robust early warning systems and evacuation plans.

The outlook remains negative due to the escalating climate threats and rising population density.
