Sunlight reflection and carbon removal proposals for “climate engineering”(CE) confront
governance challenges that many emerging technologies face: their futures are uncertain …

Solar radiation management (SRM) is a climate engineering strategy to reduce temperature
increases due to global climate change. The most well-researched SRM methodology is …

This report assesses the effects of stratospheric ozone depletion and anticipated ozone
recovery on the intensity of ultraviolet (UV) radiation at the Earth's surface. Interactions …

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 …

Solar geoengineering refers to deliberately reducing net radiative forcing by reflecting some
sunlight back to space, in order to reduce anthropogenic climate changes; a possible such …

Climate change is among the world's most important problems, and solutions based on
emission cuts or adapting to new climates remain elusive. One set of proposals receiving …

We are in the middle of a planetary crisis that urgently requires stronger modes of earth
system governance. At the same time, calls for justice are becoming increasingly …

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 …

This study assesses the impacts of stratospheric aerosol intervention (SAI) and solar
dimming on stratospheric ozone based on the G6 Geoengineering Model Intercomparison …

Geoengineering technologies aim to make large-scale and deliberate interventions in the
climate system possible. A typical framing is that researchers are exploring a 'Plan B'in case …
