Abstract

Geoengineering is a technological response to anthropogenic climate change. There are two kinds of geoengineering: Solar Radiation Management (SRM) and Carbon Dioxide Removal (CDR). SRM aims at reducing the amount of incoming solar light and CDR at reducing the CO2 concentration in the atmosphere. Over the past decades, geoengineering has moved from a fringe proposal to a more mainstream contender along with mitigation and adaptation to avert climate change. However, it faces important ethical challenges.
