Sunday morning came with news of a major disaster in a part of the Himalayas we have been planning to travel to. A part of a glacier fell into the Dhauli Ganga river right up near the part of the mountains that we wanted to visit. It sped downriver, destroying a dam, several bridges, and burying people. The count of people missing keeps rising. The work of rescue started soon, and it has been partly successful. Some of the people who were dug out will live. Finding others is proving to be difficult, and it has been very cold.
It is too early for the press to turn to the question of the reasons for this disaster, I’m afraid an old narrative will take over. Journalists are finely tuned to seek out policy errors behind the news; that is their job as part of the mechanism of checks and balances which builds a democracy. But this is not a story only of immediate policy errors. I’m afraid it feeds into a theme which had haunted my posts through last week, and which I wanted to stop writing about: the theme of climate change and a warming earth.
When you look at the featured news photo, you see people being dug out of rocks covered with glacial mud. That is part of the evidence. The other part is that the landslide accelerated down river, according to reports, traveling faster than a hydraulic hammer. The speed and the acceleration is consistent with a mass of solid accelerating under gravity. So, the underlying cause of the damage seems to be the century-long melting of these glaciers due to the warming of the earth. We have seen the glaciers of the Antarctica sliding into the ocean, the Arctic ice melting away totally. We should have seen this coming. The world’s reserves of ice, its pagosphere, is melting fast. The most immediate harm will come to people who live in high mountains.
The acceleration of the mass downstream may have been aided by the dams. The water and mud held in them could have lubricated the passage of the glacial mass, and allowed it to speed up to the extent seen. Certainly they contributed to downstream flooding. So perhaps long time human neglect has interacted with short term policy errors. Unfortunately, it is a story which could repeat. It will take very wise decision making to prevent such things from repeating. I’m also afraid we are at the beginning of climate migrations. People from the subpluvial regions of the earth have already started to migrate, creating a refugee crisis whose causes have been ascribed to economics rather than climate change (not entirely wrong, but perhaps inadequate for framing policies). Before the migration of island nations, there could be a migration of people who live in the world’s pagosphere. Since this could be mainly an internal migration, not a crossing of international borders, it may go unrecognized. But recognizing it could be a key to understanding the stresses that climate change will put on human society. But for now I’m happy to leave you with the conclusion of the tense story that began in the featured photo and ends with the one above.
Note added: Two weeks after the events, 68 people were confirmed dead. 136 are still missing, and are now presumed dead. What a tragedy!
