Geoengineering also referred to as climate engineering, is deliberate and large-scale intervention of Earth’s climate system in order to mitigate climate warming. Two kinds of techniques are involved in geoengineering, Carbon Dioxide Removal (CDR) and Solar Radiation Management (SRD). CDR is removing greenhouse gases out of atmosphere and SRD attempts to offset greenhouse effect by reducing solar energy absorption. Emission control is always the first option to mitigate climate warming, and geoengineering could serve as a backup plan as it can be mentioned in similar dissertations https://topdissertations.com/dissertation-for-sale/
