Scientists warn that Thulagi Glacial Lake in Nepal, now over 1 square kilometer and holding 10 billion gallons of water, is on an ICIMOD watchlist of 47 dangerous Himalayan lakes. The imminent risk of a glacial lake outburst flood (GLOF) threatens to unleash catastrophic floods within hours, destroying downstream communities.

This isn't just a humanitarian crisis; it's a direct attack on economic infrastructure. A GLOF from Thulagi specifically endangers four hydropower projects, along with roads, bridges, and agricultural land. The 2021 Marsyangdi River floods, which rerouted rivers and wiped out villages, provide a traumatic precedent for the scale of potential livelihood and tourism disruption.

Mitigation is underway but vastly underfunded. A $36.1 million Green Climate Fund grant aims to lower water levels at four lakes, including Thulagi, yet no early warning systems cover the immediate threat. The fundamental solution requires massive international investment in resilient infrastructure to protect billions in regional energy and development assets from an accelerating climate threat.

Quick Fact: A $36.1 million grant targets four glacial lakes, including Thulagi.
