Cover factsheet Stratospheric Aerosol Injection

Stratospheric Aerosol Injection (SAI)

Factsheet
Stratospheric aerosol injection is a proposed solar geoengineering method in which large quantities of tiny reflective particles are released into the stratosphere to cool the Earth by reflecting sunlight back into space.
cover factsheet enhanced photosynthesis

Enhanced Photosynthesis

Factsheet
Enhanced photosynthesis techniques are theoretical geoengineering technologies based on the idea that plants and algae can be genetically modified to absorb and metabolize and therefore store more carbon dioxide.
Cover factsheet microbubbles and sea foam

Microbubbles and Sea Foam

Factsheet
Microbubbles proposals suggest that by injecting millions of tiny air bubbles into the ocean or spraying sea foam onto surface waters, the albedo of large areas of ocean could be increased, thereby reflecting more sunlight back into space.
Cover Factsheet Ocean Fertilisation

Ocean Fertilization

Factsheet
Ocean fertilization is a proposed method for CO2 removal in which large quantities of micro- or macronutrients are introduced into marine areas with low biological productivity to stimulate the growth of phytoplankton.
