Geoengineering

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.

Geoengineering
Deliberate and large-scale intervention in Earth's climate system
Geoengineering is the deliberate large-scale interventions in the Earth’s climate system intended to counteract human-caused climate change. The term commonly encompasses two broad categories: large-scale carbon dioxide removal (CDR) and solar radiation modification (SRM). CDR involves techniques to remove carbon dioxide from the atmosphere and is generally considered a form of climate change mitigation. SRM aims to reduce global warming by reflecting a small portion of sunlight away from Earth and back into space. Although historically grouped together, these approaches differ substantially in mechanisms, timelines, and risk profiles, and are now typically discussed separately. Some other large-scale engineering proposals—such as interventions to slow the melting of polar and alpine ice—are also sometimes classified as forms of geoengineering.
