In this Climate Chat episode, we interview climate scientist Francisco Estrada about his recent paper assessing the risks of "Termination Shock" following the implementation of Solar Radiation Management (SRM, a.k.a., solar-geoengineering). Termination Shock is a rapid, severe warming spike that would occur if SRM were suddenly stopped, because accumulated greenhouse gases would heat the planet al...

In this Climate Chat episode, host Dan Miller discusses SRM and its possible impact on various tipping points.
