This paper presents the estimated direct costs of a stratospheric aerosol injection (SAI) program through the end of this century. It displays a range of future solar geoengineering deployment scenarios that are intended to reduce anthropogenically-caused radiative forcing beginning in 2035. The scenarios reviewed herein include three commonly modeled representative concentration pathways (4.5, 6.0, and 8.5) and three possible radiative forcing targets (halving future warming, halting warming… 

Assessing the consequences of including aerosol absorption in potential Stratospheric Aerosol Injection Climate Intervention Strategies

Abstract. Theoretical Stratospheric Aerosol Intervention (SAI) strategies model the deliberate injection of aerosols or their precursors into the stratosphere thereby reflecting incident sunlight

A subpolar-focused stratospheric aerosol injection deployment scenario

Stratospheric aerosol injection (SAI) is a prospective climate intervention technology that would seek to abate climate change by deflecting back into space a small fraction of the incoming solar

Review of possible very high-altitude platforms for stratospheric aerosol injection

Economically efficient injection of aerosols into the stratosphere for the purpose of deflecting incoming sunlight and managing the Earth’s energy budget would require high-altitude deployment

Climate response to off-equatorial stratospheric sulfur injections in three Earth System Models - Part 1: experimental protocols and surface changes

. There is now a substantial literature of climate model studies of equatorial or tropical stratospheric SO 2 injections that aim to counteract the surface warming produced by rising concentrations

Brief Communication: Reduction of the future Greenland ice sheet surface melt with the help of solar geoengineering

Abstract. The Greenland Ice Sheet (GrIS) will be losing mass at an accelerating pace throughout the 21st century, with a direct link between anthropogenic greenhouse gas emissions and the magnitude

Updated and outdated reservations about research into stratospheric aerosol injection

In this paper, we seek to ground discussions of the governance of stratospheric aerosol injection research in recent literature about the field including an updated understanding of the technology’s

Aerosol Monitoring at High Mountains Remote Station: A Case Study on the Yunnan Plateau (China)

In January 2016, a measurement campaign was carried out by the China Meteorological Administration, the Beijing Research Institute of Telemetry, and the Physics Department of the University of Naples

The Climate Change Challenge: A Review of the Barriers and Solutions to Deliver a Paris Solution

Global greenhouse gas (GHG) emissions have continued to grow persistently since 1750. The United Nations Framework Convention on Climate Change (UNFCCC) entered into force in 1994 to stabilize GHG

Linking solar geoengineering and emissions reductions: strategically resolving an international climate change policy dilemma

ABSTRACT Solar geoengineering appears able to reduce climate change risks but raises controversy, the leading cause of which is the concern that its research, development, and evaluation might



Stratospheric aerosol injection tactics and costs in the first 15 years of deployment

We review the capabilities and costs of various lofting methods intended to deliver sulfates into the lower stratosphere. We lay out a future solar geoengineering deployment scenario of halving the

Production of Sulfates Onboard an Aircraft: Implications for the Cost and Feasibility of Stratospheric Solar Geoengineering

Injection of sulfate aerosols into the stratosphere, a form of solar geoengineering, has been proposed as a means to reduce some climatic changes by decreasing net anthropogenic radiative forcing.

The Impact of Geoengineering Aerosols on Stratospheric Temperature and Ozone

Anthropogenic greenhouse gas emissions are warming the global climate at an unprecedented rate. Significant emission reductions will be required soon to avoid a rapid temperature rise. As a potential

What is the limit of climate engineering by stratospheric injection of SO 2

Abstract. The injection of sulfur dioxide (SO2) into the stratosphere to form an artificial stratospheric aerosol layer is discussed as an option for solar radiation management. The related reduction

Sensitivity of the radiative forcing by stratospheric sulfur geoengineering to the amount and strategy of the SO 2 injection studied with the LMDZ-S3A model

Abstract. The enhancement of the stratospheric sulfate aerosol layer has been proposed as a method of geoengineering to abate global warming. Previous modelling studies found that stratospheric

Strategically applied geoengineering is proposed to reduce some of the known side effects of stratospheric aerosol modifications. Specific climate goals could be reached depending on design choices

The Climate Response to Stratospheric Aerosol Geoengineering Can Be Tailored Using Multiple Injection Locations

By injecting different amounts of SO2 at multiple different latitudes, the spatial pattern of aerosol optical depth (AOD) can be partially controlled. This leads to the ability to influence the

Albedo Enhancement by Stratospheric Sulfur Injections: A Contribution to Resolve a Policy Dilemma?

Fossil fuel burning releases about 25 Pg of CO2 per year into the atmosphere, which leads to global warming (Prentice et al., 2001). However, it also emits 55 Tg S as SO2 per year (Stern, 2005),

Sensitivity of Aerosol Distribution and Climate Response to Stratospheric SO2 Injection Locations

Injection of SO2 into the stratosphere has been proposed as a method to, in part, counteract anthropogenic climate change. So far, most studies investigated injections at the equator or in a region
