What if someone wanted to deploy a massive project to try to reverse climate change today? Perhaps some researchers wanted to spray sulfur particles into the stratosphere to reflect away some of the sun’s energy, cooling the Earth in an attempt to compensate for global warming.
Or perhaps a group wanted to unload some fertilizer into the ocean, so more algae will grow and absorb carbon dioxide from the atmosphere. Their actions may have global consequences, but would such projects have to answer to a global governing body?
Such geoengineering projects — Earth-altering plans to combat global warming — sound pretty futuristic. Indeed, it would be decades before such projects are likely to be deployed, if they ever are, say scientists InnovationNewsDaily contacted. Yet a little bit of the future is already here, as researchers have just started to propose outdoor experiments for technologies that would apply to geoengineering projects. Previously, researchers studied the effects of geoengineering in labs or using computer programs, but now a few groups want to try experiments outside of the lab. Harvard University researchers David Keith and James Anderson recently grabbed headlines for a proposal to put small amounts of sulfur particles into the air, to study how such particles interact with the atmosphere.
