It's a press release. It skimps out on a detailed enumeration of everything we do know about the chemistry and dynamics of atmospheric aerosols, which has been an active research area for 60 years now. The beginner in the field needs to slog through the 2000+ pages of Pruppacher and Klett, Seinfeld and Pandis, and Finlayson-Pitts and Pitts.
The only thing new with the CLOUD results is (a) molecular-level building block understanding of the precise nucleation pathway, confirming decades of previous bulk and stochastic experiments, and (b) the fact that IIN (the mechanism whereby GCRs could enhance aerosol formation) is pretty much irrelevant anytime you get trinary sulfate-nitrate-water nucleation occurring.
> EDIT: Not surprisingly, over in /r/science [sic] they jump to the conclusion that this is a confirmation of CAGW ClimateScienceTM rather than a demonstration of how little is actually understood (and therefore cannot even attempt to be "modeled").
The only one jumping to conclusions here is you and the parallel post on the front-page of this forum criticizing Mann's tweet. In reality, this paper is a death-knell for Svensmark's GCR-climate theory; the original Kirkby et al, 2011 paper is overruled with this new understanding since it moved towards the direction of more atmospherically-relevant aerosol loadings and illustrated how the one way that GCRs could affect aerosols and thereby clouds is irrelevant in the context of the free atmosphere.
And by the way, the entire point of this paper is that the authors developed a model which very well details their experimental results:
> Our experimental measurements are well reproduced by a dynamical model based on quantum chemical calculations of binding energies of molecular clusters, without any fitted parameters.
Haven't actually worked out of them myself but I've heard good things about Atmospheric Chemistry and Physics by Seinfeld and Pandis or Introduction to Atmospheric Chemistry by Jacobs
