Could we change the weather?

The idea that people can change weather has a long history - both as part of mythology and as part of modern day conspiracy theory. But the science of geoengineering is one that some scientists think could be an important opportunity to give the world space to make progress on reducing CO2 emissions. But geoengineering, including stratospheric aerosol injection, remains very controversial and little understood. Alistair Duffey is a scientist at University College London and one of a small number of researchers looking into solar geoengineering. He spoke about his work, the risks and potentialities that go with it, and whether it might be something we can expect in the near future. Alistair Duffey mentions a novel about this subject, Termination Shock.
