On one hand “A journey of a thousand miles starts with a single step.”
On the other hand unless there is a plan/mechanism to take the remaining 1.7 milion steps why even start? I have not studied the framework of the Paris agreement to know if it really puts a mechanism place to complete the journey.
Certainly, the goals are so modest and the measuring process so poor that they fall well within in the error range of any climate models. Meaning if we get 2100 (I won’t of course) and the climate isn’t a disaster we will have no way of knowing if the Paris impact had any impact at all But if the climate is a disaster in 2100, then we know that it wasn’t enough. The problem with feel good, symbolic gestures is they give people a false sense of security, I don’t which group the Paris accord falls into an important step or feel good gesture.
