Climate Journal Club: "Geoengineering, the world's largest control problem"
Date and Time
Location
GS Cristi Proistosescu leads this week's ClimaTea seminar on geoengineering. He summarizes the discussion as the following:
Solar Radiation Management/Sunlight Reflection Methods (SRM) is a proposed geoengineering technique that might reduce damage from anthropogenic climate change. However, there is no one optimal method of applying SRM - the degree of compensation will vary, with residual climate changes larger over some regions and time scales than others.
The papers we will be discussing this week treat SRM as a feedback and discuss geoengineering as a control problem. The authors discuss (a) how to properly design an SRM feedback in order to manage significant uncertainty in both radiative forcing and the climate system's response; (b) how to optimize the distribution of radiative effect to minimize regional disparities.
