Not a chance anything significant happens.

Politicians are pathetic and power hungry with a focus on the next election term. In front of the catastrophy hitting us, they keep stuttering the same old mantra: "bbbbut jooobs, bbbbut ekkkonomy, bbbbut grooowth". The industrial and carbon lobby put all their weight in maintaining this message and status quo. And the general population is woefully unwilling to change its own habits: it's always the others who are the big polluters and must make the effort. "Not me, the industry must... China must... The rich must... Africa must not..."

Avoiding a +2°C average increase? Forget it, that ship has long sailed and cannot be stopped.

With no one doing anything significant, the fact is that the +5°C scenario that climatologists *know* is likely but they dare not communicate too much about will happen. Say bye to ice caps, say bye to low-level coastal lines. Consequences will be a slow cataclysm, still faster than people think, unrolling it's dramatic consequences over the next 50 years, costing a billion humans an early death.

Forget about altering the course of global warming, just prepare for it and make choices to enable you and your loved ones to live a happy life in that coming new world.
