🌡️London War Game Simulates Geoengineering Race
Geoengineering arms race looms as distrust grows
TL;DR
A war game in London simulated a global race to develop geoengineering tech, highlighting the risks of an uncontrolled deployment. Players from the US and China clashed over research and control, underscoring the need for international cooperation.
A war game in London simulated a global race to develop geoengineering tech, with players from the US and China clashing over research and control. The exercise revealed the risks of an uncontrolled deployment, with some regions suffering from unintended consequences. The cooling effect of solar geoengineering is widely accepted, but the fallout is uncertain and unequal, with sub-Saharan Africa experiencing drying and the Atlantic seeing more intense tropical storms. The game also highlighted the threat of falling behind a rival, with neither the US nor China willing to cede control over the global thermostat.

Key Points
A war game in London simulated a global race to develop geoengineering tech, with players from the US and China clashing over research and control.
The game unfolded over simulated meetings set at three points in time: the present, September 2027, and September 2028.
Players representing both the US and China refused to sign a deal that constrained their pursuit of research considered to be in their 'national interest'.
China approached a player representing SpaceX to float the idea of a technology-sharing program, but the US demanded an international investigation and abandoned the talks.
The former British diplomat with a background in national security said that there is an interdependence between solar radiation management and nuclear arms dynamics.
