Maybe it is easier to address various problems in an autocracy, but there's still way more that democracies can do to tackle these and other problems. In fact, there are plenty of democracies that are doing a lot to curb carbon emissions or fight other problems. And in the end, reducing carbon is just another problem that requires political action.

I suppose it's true that in an autocracy, there are less people that need to be convinced that something is a problem before something can be done, but it's not like democracies are doomed to indecision. We have been able to take action before, we can take action on this. It's not that hard. But we do need to stop making excuses.
