This is exactly why I made sure when buying my house/section that it was more than 5m higher than sea level and inland from the coast. Not that that will mitigate the societal collapse following the glaciers’.
The world might be able to geoengineer saving one maybe two glaciers. But not all of them, not Greenland’s icesheet and not the entire Antarctic icesheet.
It’s pragmatism. Hope for the best, prepare for the worst.
