CBC’s Quirks and Quarks: Geoengineering: the good, bad and the ugly of this ‘break glass in case of emergency’ fix

Geoengineering could help us avoid certain tipping points, but not if we drag our heels, according to a climate modelling study. It found that efforts to inject aerosols into the stratosphere to halt the weakening of a vital ocean current in the Atlantic would be a lot less effective if we delay until 2080. That is just one of many geoengineering ideas under consideration to counter the effects of global warming, but they come with huge risks, forcing scientists to weigh their pros and cons if we don’t decarbonize quickly enough. Dr. Julienne Stroeve, professor of polar climate science at the University of Manitoba, argues that resources would be better spent advancing carbon capture technology rather than furthering work on risky geoengineering ideas.
