Reconstructing Quantum mechanics from 5 axioms, but the axioms seem a bit complicated at first sight: probabilistic description, simplicity (defined in a rather non-simple way), subspaces, composite systems and continuity. Overall, this paper tries hard to convince that quantum probabilities are “special”, but I think that it does so by unnecessarily restricting the set of allowed “classical” experiments (notably, experiments where you don’t know everything).

If you are to debate CO2 and other greenhouse effects, per-country and per-capita emissions may be useful.
