Warnings from a Warming Himalayas
As I write this, over 1,300 lives are confirmed lost and many thousands are still missing in the floods in Nepal, as the mighty Himalayas came down as rubble. This is an enormous and painful human tragedy, but it is also about wilful actions and inactions of humans. It is about our mindset, the belief that we can re-engineer everything; that we are in control of the universe and all things in it. This is on us. Let me break this down. What happened in Nepal on August 26? The images are of the mountain coming down as the flash flood and massive quantity of debris buried everything in its path. We know now that this flash flood was not caused by an extreme cloudburst. It was triggered by the collapse of a high-altitude glacier near the Langtang Lirung peak. An estimated 142 million cubic metres of ice and rocks were dislodged, creating a 5.2 magnitude seismic event. This led to the formation of natural dams, behind which water and moraine accumulated. When the dams broke, they unleashed devastating floods downstream.
