The political consensus surrounding climate policy is collapsing. If you are not aware of this fact you will be very soon. The collapse is not due to the cold winter in places you may live or see on the news. It is not due to years without an increase in global temperature. It is not due to the overturning of the scientific consensus on the role of human activity in the global climate system.
It is due to the fact that policy makers and their political advisors (some trained as scientists) can no longer avoid the reality that targets for stabilization such as 450 ppm (or even less realistic targets) are simply not achievable with the approach to climate change that has been at the focus of policy for over a decade. Policies that are obviously fictional and fantasy are frequently subject to a rapid collapse.
