Geoengineering

 The large-scale operation of a specific process used to tackle the effects of the climate changes on the earth by directly removing CO2 from the air or limiting up the amount of sunlight reaching the planet's surface. Geoengineering also most commonly refers to climate engineering, Geological engineering, Engineering geology, Geotechnical engineering and Geophysical engineering. Geoengineering approaches are sometimes viewed as potential options for limiting the changes and impacts on the earth’s climate. The measures employed for addressing climate changes have economic, physical and political limitations.  Most of the experts advises against relying on the climate engineering techniques as a main solution to global warming. This global climate and the solar radiation reflectance are controlled by several mechanisms including Earth’s surface albedo, cloud coverage and the presence of atmospheric greenhouse gases such as carbon dioxide (CO2).
