Aperçu des méthodes de réflexion de la lumière solaire
Les méthodes de réflexion de la lumière solaire (MRS) sont des approches hypothétiques visant à abaisser les températures mondiales en augmentant la quantité de lumière solaire réfléchie vers l’espace.
Sunlight
Space-based SRM
Reflective material between the earth and sun could scatter light, but delivery would be extremely costly.
Stratospheric aerosol injection (SAI)
Tiny particles released in the stratosphere could reflect a small fraction of sunlight, producing a global cooling.
Cirrus cloud
thinning (CCT)
Seeding might thin cirrus clouds, allowing more heat to escape to space.
Heat
Surface albedo modification
Brighter surfaces could reflect more sunlight, but global cooling potential is limited.
Marine cloud brightening (MCB)
Sea-salt particles could be sprayed from ships to enhance the reflectivity of low-lying clouds.
