Stratospheric aerosol injection
A
Airplanes release tiny aerosol particles
that reflect light back into space.
Cirrus cloud thinning
B
The least understood method, seeding
thin cirrus clouds in the upper tropos-
phere with ice nuclei could reduce
their lifespan and increase cooling.
Marine cloud brightening
C
Boats release aerosol particles that
increase the reflectivity of low clouds.
