Q&A: Aerospace engineer discusses the design challenge of solar geoengineering

Solar geoengineering—artificially reflecting sunlight back into space—is a double-edged sword. It would cool the rapidly warming planet, but is it too risky to consider as a viable option? Douglas MacMartin, an aerospace engineer and visiting scholar at the Stanford Woods Institute for the Environment, thinks of solar geoengineering as a design problem. His research is dedicated to understanding how to most effectively optimize the cooling effects from climate engineering while minimizing the potential risks to humans and ecosystems. That way, if the time comes that we need to deploy it to avert the worst effects of climate change, we'll be ready.
