Termination shock could make the cost of climate damage even higher | Solar geoengineering could halve the economic cost of climate change, but stopping it would cause temperatures to rebound sharply, leading to greater damage than unabated global warming

This is kind of a big deal — [the long atmospheric lifetime of CO₂](https://www.nature.com/articles/climate.2008.122.epdf?sharing_token=1S_0Th24Bg9IxPZtwFIYwtRgN0jAjWel9jnR3ZoTv0PofJzPf-DjN3kkXOM-08nJJHq-TfOn6WSCYcYH6dQJGgBhcBGZVDEw5nwzzG-DShFkwJd5X_JP9M_eVhiVCYUoH6csR8n1dlkQtGW9g4BvVi_siLK049-Rhst5X0zoztnMsykHZp76aXztJcG3m-FQJeVtzLpEUqlf5FmgJbT2fgGBPjj0hDgZipqY9bQOjVv5ZHZzULTgyT55tNRDJvBKgLa6db2-2k49pDXaehOgiNToP1XLAR_Auu0tJE4BdU8%3D) means that once started, people need to maintain the technical infrastructure for geoengineering for longer than civilizations last.
