Super El Niño could amplify Himalayan warming after deadly avalanche
Rescue teams are still responding to a landslide-triggered avalanche and floods that have killed over 1,000 people in Nepal and Tibet, while scientists warn a strong upcoming El Niño may intensify regional warming.
A catastrophic debris avalanche and subsequent flooding in Nepal and Tibet have claimed over 1,000 lives, prompting continued rescue and cleanup operations. Scientists attribute the trigger to a huge landslide high in the Himalayas, a phenomenon increasingly linked to warming mountain environments. The region is now facing a potentially historic super El Niño, which could boost summer heat and produce a drier monsoon season, heightening melt risks.
Climate specialists Kaustubh Thirumalai of the University of Arizona explain that El Niño makes Himalayan weather less predictable, while Mingfang Ting of Columbia University's Climate School warns that a shift to La Niña could add heavy precipitation, stressing glaciers further. Although August’s unusually warm temperatures may have contributed to slope instability, researchers cannot yet confirm a direct El Niño influence on the recent disaster. They advise close monitoring of the upcoming El Niño’s evolution to anticipate heightened warming and related hazards.
Why it matters
Understanding how a strong El Niño could worsen Himalayan climate risks helps prepare vulnerable communities for future disasters.
