The US should urgently develop and test GE

"The most plausible route to averting the worst impacts of climate change is geoengineering. That such an approach—highly speculative and untested—is the current most feasible option speaks to how implausible a global net-zero transition currently is. Geoengineering includes radical ideas such as spewing aerosols into the stratosphere to reflect sunlight back into outer space and cool the planet. The United States should urgently develop and test such approaches at ever greater scales to prepare for a “break glass” emergency when these techniques may need to be deployed. The United States should also carefully evaluate the risks of these technologies and prepare to deter other countries from unilaterally deploying them, or cooperate internationally to do so."
