It is not late, but we have to start seriously
This study published in Nature is very interesting because makes numbers about emission targets, the peak emission year and the consequences up to 2100. The study recognizes the great grade of uncertainty in some aspects as the absolute amount of consequences and this in my opinion gives it more credibility.
On the other hand it states clearly than the date and the amount of the peak of emission is more important than the later reduction rate. It says that even if it very difficult to know what will happen exactly the proportion of it will be much lower if we peak our emissions fast.
I find this result interesting, important and encouraging at the same time. Because it would not be so difficult to peak world emissions:
- Most European nations and maybe the USA have done so
- The BRICS, concretely China and India had better add new power by renewables than coal, it makes sense in many aspects.
- The poorest countries do not have much influence in the decisions nor in the emissions, but for them too renewables with help of richer countries make more sense.
Going further to the 80% reduction from current emissions as the final target seems much more difficult but this study finds we have some extra time for that. So let’s start with the first step: the world emissions peak.
