The Nepal catastrophe that killed over a thousand is not an isolated localized accident but stark manifestation of accelerated global warming, writes Shashi Tharoor. And it carries bitter irony: Nepal, whose greenhouse emissions are virtually negligible, bears most brutal consequences of global climate change, while its vast industrialised neighbours, especially to north, account for substantial portion of atmospheric warming driving Himalayan glacial collapse.
Glaciers don't recognise international boundaries, nor glacial lake bursts, atmospheric currents. When glacial lake bursts, landslide dams transboundary river, or ice-rock avalanche releases millions cubic metres of meltwater creating barrier lake that could burst anytime, deluge flows downstream across sovereign frontiers.
During a conclave in Kathmandu, Rabi Lamichhane of Rastriya Swatantra Party noted whatever prevailing geopolitical frictions, strategic rivalries or sovereign boundary disputes among India, China and Nepal, all three unavoidably share single unified mountain system. Physical unity is undeniable.
Yet governance of Himalayan biome remains deeply fragmented. China controls Tibetan Plateau, source of Asia's major rivers - Yarlung Tsangpo (Brahmaputra), Indus, upper tributaries of Ganges like Bhote Koshi and Karnali. Beijing's approach to sharing hydrological data during monsoon has been transactional, bilateral MoUs rather than automatic open data. Lower-riparian nations left in dark during critical moments. During previous incidents involving natural dams from massive landslides in Tibet, both Indian authorities in Arunachal and Assam and downstream Nepali communities faced terrifying delays receiving actionable flow rates or structural assessment from Chinese stations. Similarly flash floods along upper trans-boundary tributaries like Pareechu or Bhote Koshi - downstream countries forced to rely on layered commercial satellite imagery rather than immediate official alerts.
Tharoor proposes three pillars for tripartite environmental mechanism to succeed where past arrangements stumbled, transcending political posturing:
First, information-sharing must become automated real-time protocol - high-altitude hydromet stations, seismic sensors, automated water-level gauges across Tibet, northern Nepal, Indian Himalayan region must feed into shared regional data grid. Downstream communities cannot afford to wait hours for administrative clearances.
Second, joint ecological research - mapping dangerous glacial lakes across Hindu Kush-Himalayan range, assessing hanging glaciers, predicting destabilising landslips requires joint scientific expeditions, cross-border remote sensing, shared ecological modelling.
Third, feasibility-based joint action on ground where high-risk glacial lakes threaten settlements across borders, joint engineering interventions - controlled siphoning, artificial drainage channels - must be undertaken collaboratively. Coordinated disaster drills and cross-border environmental conservation projects can build functional trust among military and civilian disaster response agencies that otherwise view each other through lens of geopolitical suspicion.
Himalaya is warming significantly higher than global average, threatening water security, safety, livelihoods of over a billion downstream. Nations can negotiate political boundaries, but not physics, geology, atmospheric temperatures. Mountains bind India, China, Nepal to shared destiny.
