Solar geoengineering might reduce the economic impacts of climate change, but abruptly halting it could trigger a rapid temperature rebound known as termination shock, potentially causing greater damage than unchecked warming. Researchers warn that this risk underscores the need for sustained international cooperation. Without emission cuts, global temperatures could rise 4.5°C by 2100, leading to $868 billion in damages.
