There are presently five reflectivity intervention methods that are potentially low enough risk and cost-effective.

It may be cost-effective to thicken winter ice on the Arctic Ocean

Eliminating sulfur from ship fuels has likely accelerated global warming by 2-3 years

Jordan and Henry

Another study concludes that reducing sulfur in ship fuels has reduced brightness of marine clouds, increasing warming

Gettelman and others

Warming increased in 2020 when sulfur was eliminated from fuel for ships that cross the oceans, thereby reducing brightness of marine clouds.
