ABSTRACT

Technologies for Solar Radiation Management (SRM) could limit global
warming by manipulating the Earth’s radiation balance. A major objection to
SRM is the termination problem: the catastrophic consequences that are
likely to result from its sudden discontinuation. The termination problem
limits the reversibility of policy choices and poses the risk of
inadvertent or enforced program collapse. It is often considered a major
impediment to the governability of SRM. In a first attempt to
systematically engage with the question of institutional design for
resolving the termination problem, the scenarios in which the termination
problem arises as well as their respective drivers are identified.
Scenarios and drivers are then used to derive institutional solutions in
the form of excludable benefits, scientific oversight and phase-out
mechanisms. While other objections to SRM may remain valid, it is concluded
that the termination problem raises fewer challenges for international
governance than is usually assumed.

Abstract

The problem of the optimal control of aerosol emissions into the
stratosphere to stabilize the Earth’s climate is considered based on the
zero-dimensional energy balance model. The global surface-temperature
deviation from the undisturbed value is the state variable, and the albedo
of the artificial aerosol layer, whose time variations are functionally
related to the change in the total mass of aerosol particles and,
consequently, the rate of their emissions, is the control variable. The
problem is solved with and without consideration for the system phase path
and control variable constraints for the given performance measure
(objective function). Unlike previous studies, the aerosol emission
scenarios are not set a priori, but represent a rigorous solution of the
optimal control problem, ensuring the minimization of the objective
function. The method is illustrated using the RCP8.5 scenario of growing
concentration of greenhouse gases in the atmosphere. The approach
considered in this paper can be easily extended to the cases of applying
other known methods of climate engineering to manipulate the climate.
