👉 Geoengineering refers to large-scale interventions in the Earth's natural systems aimed at counteracting climate change or other environmental issues. It encompasses two primary categories: solar radiation management (SRM) and carbon dioxide removal (CDR). Solar radiation management involves techniques to reflect more sunlight back into space, thereby cooling the planet. Examples include stratospheric aerosol injection and marine cloud brightening. Carbon dioxide removal focuses on capturing and storing atmospheric CO2, either through direct air capture technologies or by enhancing natural processes like afforestation and ocean fertilization. Geoengineering aims to address the root causes of climate change but is controversial due to potential unintended consequences and ethical considerations.
