Geoengineering: Science Fiction or a Solution to the Climate Crisis? | GZERO World

What are the most promising climate solutions? Elizabeth Kolbert discusses the three types of technologies that are being considered to address climate change, which include cutting edge, science fiction-like technologies like geoengineering, pulling carbon out of the atmosphere and nuclear fusion. Kolbert, a Pulitzer Prize winning climate journalist, spoke with Ian Bremmer on GZERO World about the opportunities and unknowns involved in assessing these extreme solutions. "You can say, 'Well, we've unwittingly geoengineered the planet, let's try to think this through rationally and can we come up with technologies like solar geoengineering to mitigate or counteract that?'" The episode is airing on US public television starting April 16.
