Cloud brightening for climate fever

Cloud brightening for climate fever

Kelly Wanser is a climate activist who wants to use a strategy called cloud brightening to fight climate change, using a naturally occurring process to bounce rays from the sun back out to space. She and others have described it compellingly as “emergency medicine for the earth’s climate fever,” and suggest it could buy us more time to implement policies addressing the root causes of climate change. But climate change is a planetary problem – so who gets to decide what countries or groups are allowed to take the risk of geoengineering to fix it? How can one country pursue a risky mitigation strategy if neighboring countries would be the most adversely affected if things went wrong?
