Climate change is an urgent issue prompting a shift from fossil fuels to renewable energy sources. However, progress has been slow, and climate stability is increasingly at risk.

This urgency has led to considering geoengineering, or climate engineering, which involves manipulating the climate to combat global warming. 

Some geoengineering methods include reflecting sunlight back into space and direct air carbon capture. The idea of solar radiation management, such as marine cloud brightening and stratospheric aerosol injection, mimics natural phenomena like volcanic eruptions to cool the planet.
