True. On the other hand, people in democracies of Western type overlook the obvious: bureaucracy is a core element of democracy, because it does not slow down all processes meaninglessly, but provides a system of checks & balances that allows dissent and thus ensures social balancing mechanisms. Inevitably, it is slower than in a dictatorship. It would be slower even if bureaucracy were made more efficient.
One cannot desire an expansion like in dictatorships while maintaining democracy at the same time.
I agree with you 100% - logically. The argument "but the others" then no longer applies to us if, for example, China soon gets far ahead of us in renewable energies (which I assume). Autocracy / democracy aside. This "argument" simply no longer exists. That was all I wanted to point out.
So, in the long run, things will go slower and the +1.5°C target will certainly, and the old +2.0°C target very likely, be missed. And yet life must go on.
But you should tell that to the people who currently live in regions of the Earth or have children / grandchildren there who will no longer be inhabitable by the end of the century ;)
Which regions these will be is sadly already agreed upon in scientific circles. This is not a matter of belief.
