Plan A+: How stratospheric aerosol geoengineering could play a role in climate policy

In this talk, Dr. Peter Irvine (UCL, Earth sciences) will introduce the idea of Stratospheric Aerosol Injection (SA) geoengineering, a proposal that aims to mimic the cooling effect of major volcanic eruptions, and he will explain the role it could play in climate policy. His talk will address the feasibility, side-effects and potential of SAI as a means of reducing the risks of climate change, and the broader concerns around this idea. He will also explain that while there’s a risk that it could undermine the motivation to tackle anthropogenic emissions of CO2, there are reasons to believe it might actually make it easier to address our impact on the carbon cycle.
