The optimal combined design of climate mitigation and geoengineering

TL;DR

This paper investigates the combined design of climate mitigation and geoengineering, demonstrating that such an approach can achieve climate goals with better economic utility and fewer constraints than mitigation alone.

Contribution

It introduces a novel combined approach to climate mitigation and geoengineering, showing its feasibility under strict emission and temperature constraints.

Findings

Combined approach offers better economic utility.

Feasible solutions exist even when mitigation alone does not meet constraints.

The approach reduces emission control rates and temperature increases.

Abstract

Combined climate mitigation/geoengineering approach has better economic utility, less emission control rate and temperature increase than mitigation alone. If setting the 50% reduction rate and 2^\circC temperature increase as constrains, we find there is no a feasible solution for emission control, but combined design is still available.
