1/ I disagree a bit, but likely circle back to same conclusion as Katharine. SSPs are socioeconomic stories, not forcing scenarios. They become forcing trajectories when run through IAMs that integrate a bunch of assumptions with climate/energy/land systems to generate emissions scenarios.

RCP and SSP scenarios are not emission scenarios.
I repeat: they are not emission scenarios.
They are radiative forcing scenarios.
Forcing = human emissions + the response of the climate system to those emissions
You can only back out emissions by making assumptions about climate sensitivity.
