Geoengineering is the deliberate large-scale manipulation of the Earth’s environment to counteract climate change.
There are several proposed methods of geoengineering, including:
-
Solar radiation management: This involves reflecting a small amount of incoming sunlight back into space, thereby reducing the amount of heat absorbed by the Earth’s surface.
-
Carbon dioxide removal: This involves removing carbon dioxide from the atmosphere and storing it underground or in the ocean.
-
Cloud seeding: This involves injecting particles into clouds to increase the amount of precipitation.
-
Ocean fertilization: This involves adding nutrients to the ocean to increase the growth of phytoplankton, which can absorb carbon dioxide from the atmosphere.
It’s important to note that geoengineering is still a largely untested and uncertain field. While it could potentially provide a way to mitigate the effects of climate change, it also has the potential to create unintended consequences and could have negative impacts on the environment and human society.
Also, there is a lot of debate on the ethics and governance of geoengineering, as it is a global issue with potential unintended consequences. Most geoengineering methods have not been fully tested and have unknown long-term effects
