Yup. Geo-engineering based on solar radiation management (SRM) is probably one of the drastic options we have to try to mitigate climate change effects. That said, the quoted paper's conclusion is that the increase in yields from reduced heating would more or less cancel out the loss in productivity from reduced sunlight. Taking that conclusion at face value, it simply says that there is no net agricultural impact from aerosel based SRM which honestly... is pretty awesome.
