Solar radiation management

Solar radiation management Solar radiation modification (SRM) (or solar geoengineering) is a group of large-scale approaches to reduce global warming by increasing the amount of sunlight that is reflected away from Earth and back to space. It is not intended to replace e ...

Stratospheric aerosol injection (climate engineering) Solar radiation reduction due to volcanic eruptions, considered the best analogue for stratospheric aerosol injection. Stratospheric aerosol injection (SAI) is a proposed method of solar geoengineering (or solar radiation modification) to reduc ...

Marine cloud brightening Marine cloud brightening (MCB), also known as marine cloud seeding or marine cloud engineering, may be a way to make stratocumulus clouds over the sea brighter, thus reflecting more sunlight back into space in order to limit global warming. It i ...

Cool roof Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to ...

Space sunshade A space sunshade or sunshield is something that diverts or otherwise reduces some of the Sun's radiation, preventing it from hitting the Earth and thereby reducing its insolation, which results in reduced heating. Light can be diverted by diff ...

Carbon dioxide removal

Carbon dioxide removal Carbon dioxide removal (CDR) is a process in which carbon dioxide () is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.IPCC, 2021:Annex VII: Glossar ...

Biochar Biochar is a form of charcoal, sometimes modified, that is intended for organic use, as in soil. It is the lightweight black remnants remaining after the pyrolysis of biomass, consisting of carbon and ashes. Despite its name, biochar is steril ...

Bio-energy with carbon capture and storage Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon dioxide (CO2) that is produced. Greenhouse gas emissions from bioenergy can be low because when vegetation ...

Ocean fertilization Ocean fertilization or ocean nourishment is a type of technology for carbon dioxide removal from the ocean based on the purposeful introduction of plant nutrients to the upper ocean to increase marine food production and to remove carbon dioxid ...

Enhanced weathering Enhanced weathering, also termed ocean alkalinity enhancement when proposed for carbon credit systems, is a process that aims to accelerate the natural weathering by spreading finely ground silicate rock, such as basalt, onto surfaces which speeds ...

Arctic geoengineering Glacial geoengineering is a set of proposed geoengineering approaches that focus on slowing the loss of glaciers, ice sheets, and sea ice in polar regions and, in some cases, alpine areas. Proposals are motivated by concerns that feedback loops ...

Cirrus Cloud Thinning Cirrus cloud thinning (CCT) is a proposed method of climate engineering. Cirrus clouds are high cold ice that, like other clouds, both reflect sunlight and absorb warming infrared radiation. However, they differ from other types of clouds in that ...

Sea ice refreezing Sea ice refreezing refers to various climate engineering techniques aimed at directly facilitating the formation or restoration of ice in Polar regions of Earth, polar regions, particularly in the Arctic Ocean. These approaches are being investigat ...
