Could SRM undermine emissions cuts?
Sunlight reflection methods (SRM) could cool the planet, but there are fears it could delay progress on emissions cuts and carbon removal.

GLOBAL TEMPERATURE INCREASE
IF SRM DELAYS PROGRESS
Delays would also commit future generations to SRM (or global warming) for longer.
Delaying emissions cuts would increase the amount of cooling needed from SRM.
