I interpret climate inaction not as science ineptitude, but as defecting in a prisoners dilemma sense. The high capita emitters (AU/US/CA/NZ) are refusing to slow down economic growth (each country has to slow down to different degrees, depending on their existing energy mix), and are relying on other nations to make progress. Rich countries will adapt. Poor country may not have the resources to do this, and thus climate inaction is an inequality issue, not just a scientific issue. Politicians respond to votes and slowing economic growth is not popular. Either rich countries will willingly sacrifice growth to help the poor of the world (not going to happen), or we encourage international cooperation. This is what's happening (Paris, Kyoto), albeit with defectors who need to be punished.
