**Gangtok, Sikkim, November 2, 2024** – A catastrophic glacial lake outburst in Sikkim has underscored the urgent need for climate change mitigation, as rising temperatures threaten the stability of these natural wonders.
The South Lhonak lake, located in Sikkim, has seen its size expand dramatically over the past few decades, growing from a mere 17 hectares in 1977 to a formidable 167 hectares by 2023. This dramatic increase in size is directly linked to glacial retreat, a significant consequence of global warming.
The lake, fed by three glaciers, acts as a hydrological buffer, holding back meltwater from the surrounding mountains. This, however, poses a significant risk to downstream communities as the moraine dam that contains the lake is increasingly susceptible to breaches.
Last year, heavy rainfall overwhelmed the moraine dam, resulting in a devastating glacial lake outburst. The flood surged down the Teesta River, causing its levels to rise by six meters and leading to the collapse of the Teesta III dam.
Scientists at IIT-Roorkee warn that a future outburst from South Lhonak could unleash a devastating surge of over 12,000 cubic meters of water per second, posing a serious threat to downstream settlements.
This event serves as a stark reminder of the dangers posed by climate change and the need for proactive measures to monitor and mitigate the risks associated with glacial lake outbursts. The incident underscores the importance of understanding these beautiful, yet potentially dangerous, natural wonders.
