The threats to the Himalaya that rose and retreated this year
Live MintA single year in the vast timeline of Himalayan history is all but insignificant. Though it has caused enormous human suffering and economic hardship, a dramatic reduction in carbon emissions, on account of India’s lockdown, provided a brief respite from airborne pollution and the immediate effects of greenhouse gases. Aside from demonstrating convincingly how vehicular exhaust and industrial smog veil the sky, these few short months of clarity also provided the mountains with a momentary reprieve from particles of carbon and other forms of dust that are carried by the wind to settle upon snowcaps and glaciers, darkening their surfaces and causing them to absorb more sunlight and melt at a faster rate. In the year ahead, as we eventually begin to emerge from the Covid-19 crisis, it is unlikely that anyone will recall or appreciate the recent environmental lessons the Himalaya have taught us. Tectonic forces that began fifty million years ago, when primordial continents collided, continue to push the Himalaya skyward while the corrosive and creative flow of water constantly scours the land even as it generates new life.
