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.
