Geoengineering, also known as climate engineering, refers to the deliberate large-scale intervention in the Earth's natural systems to mitigate the impacts of climate change. The term is derived from the Greek words geo (meaning "earth") and engineering, reflecting the application of engineering principles to planetary-scale environmental issues. In Hebrew, geoengineering is translated as הנדסה גאורגית (handasa geurgit). Other relevant translations include Géo-ingénierie in French, Geoingeniería in Spanish, and Geo-Ingenieurwesen in German. Geoengineering encompasses a range of techniques, broadly categorized into two main types: carbon dioxide removal (CDR) and solar radiation management (SRM). CDR methods aim to remove greenhouse gases from the atmosphere, such as through afforestation, direct air capture, or ocean fertilization. SRM techniques, on the other hand, seek to reflect sunlight away from the Earth, potentially through stratospheric aerosol injection or marine cloud brightening. While geoengineering presents potential benefits in combating climate change, it also raises significant ethical, political, and environmental concerns, including uncertainties about its long-term effects and the potential for unintended consequences.
