"Apocalyptic future scenarios don't become likely unless we fail to transform our energy system by 2050."

Odd that you would say that and think yourself informed on the topic. Steven Chu (Energy Secretary under Obama) and a physicist reports that we are going to exceed 600ppm 'no matter what'. He also admits to extremely dangerous warming levels to soon be reached. Even if all carbon emissions stopped, this will still happen because many former carbon sinks are now emitting carbon. The truth is this: apocalyptic scenarios are extremely likely to happen now.

Even your energy claims are factually wrong: http://energyskeptic.com/2017/we-all-fall-off-the-net-energy-cliff-in-2022-just-6-years-away/

It's panic time (seriously).
