A sunshade could potentially be one climate engineering method for mitigating global warming through solar radiation management, because internationally negotiated reductions in carbon emissions may be insufficient to stem climate change.
This could be a potential tool to reduce global warming. [2] Cirrus cloud thinning is an alternative category of climate engineering, in addition to solar radiation management. In 2021 the IPCC described CCT as a proposal "to reduce the amount of cirrus clouds by injecting ice nucleating substances in the upper troposphere." However it reported ...
If climate change causes low-level cloud cover to become more widespread, then these clouds will increase planetary albedo and contribute to cooling, making the overall cloud feedback negative (one that slows down the warming). But if clouds become higher and thinner due to climate change, then the net cloud feedback will be positive and ...
Research has been conducted into other potentially less dangerous SRM technologies, including marine cloud brightening, which involves the spraying of seawater from ships to make clouds more ...

Solar radiation modification (SRM) (or solar radiation management or sunlight reflection methods [1] or solar geoengineering), is a group of large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.
The overall impact of clouds on global climate depends on factors such as cloud type, altitude, thickness, and the amount of water or ice they contain. Thin, high-altitude cirrus clouds tend to have a net warming effect, since they allow incoming solar radiation to pass through while trapping heat radiating from the Earth's surface.
Marine cloud brightening: a proposed technique that would make clouds brighter, reflecting a small fraction of incoming sunlight back into space in order to offset anthropogenic global warming.
