Geoengineering is a term that describes the use of technologies to manipulate the environment of the Earth in order to combat climate change. There are two types of geoengineering: “mitigation” geoengineering, which focuses on reducing greenhouse gas emissions, and “adaptation” geoengineering, which focuses on adapting to the effects of climate change.

There are several methods of geoengineering :

  • Carbon sequestration: This involves capturing carbon dioxide (CO2) emitted by factories and power plants and then burying it in geological reservoirs.

  • Albedo modification: This involves reflecting more sunlight to reduce global temperature by using methods such as the use of space reflectors.

  • Forest regeneration: This involves planting trees to absorb carbon dioxide from the atmosphere.

  • Phyto-extraction: This involves growing plants that absorb carbon dioxide from the atmosphere and then using them to produce biofuels.

  • Using green fertilizers to increase plant growth to increase the amount of carbon stored in soils.

  • Modifying oceans to increase carbon storage capacity or to remove carbon dioxide from the atmosphere.

  • Modifying ocean currents to reduce global temperature or to reduce greenhouse gas emissions.

The potential benefits of geoengineering include:

  • Reducing greenhouse gas concentrations in the atmosphere by removing CO2
  • Mitigating the effects of climate change, such as reducing global temperature or modifying precipitation.
  • Slowing the pace of climate warming by reducing the amount of sunlight that reaches the Earth’s surface
  • Increasing carbon storage capacity by storing carbon in geological reservoirs, which can help reduce greenhouse gas emissions and increase carbon storage capacity.
