The Download: the solar geoengineering race, and future gazing with the The Simpsons

Last week, an American-Israeli company that claims it's developed proprietary technology to cool the planet announced it had raised $60 million, by far the largest known venture capital round to date for a solar geoengineering startup. The company, Stardust, says the funding will enable it to develop a system that could be deployed by the start of the next decade, according to Heatmap, which broke the story. As scientists who have worked on the science of solar geoengineering for decades, we have grown increasingly concerned about emerging efforts to start and fund private companies to deploy technologies that could alter the climate of the planet. We also strongly dispute some of the technical claims that certain companies have made about their offerings. This story is part of Heat Exchange, MIT Technology Review's guest opinion series offering expert commentary on legal, political and regulatory issues related to climate change and clean energy. Can "The Simpsons" really predict the future?
