Geoengineering is the deliberate, large-scale intervention in Earth’s natural systems to combat climate change and its effects. It encompasses various strategies aimed at reducing global temperatures and mitigating environmental impacts. These strategies are broadly categorized into two types: carbon dioxide removal (CDR) and solar radiation management (SRM). CDR techniques focus on removing CO2 from the atmosphere through methods such as afforestation, ocean fertilization, and direct air capture. SRM techniques aim to reflect a small percentage of the sun’s light and heat back into space using methods like stratospheric aerosol injection and cloud brightening. While geoengineering holds potential for addressing climate change, it also raises significant ethical, environmental, and political concerns that require careful consideration and governance.
