Yes, that could have been written. That there are some people who are readily throw humanity into the biggest crisis for their own profit.
The situation is very dire. There is hardly done anything to improve the situation and there are people who misinform and spread doubt. Scientists and activists get ridiculed and attacked.
That all can be written. I just don’t find the comparison to pre WW2 very matching.
This could be interesting to be studied more. All too often I hear “we need to stay optimistic to act” and “doomerism leads to inaction” without anything to back that up.
Decades of optimism about climate change have lead to hardly any action.
Personally I believe the average person needs to worry much more than they do now. While more people know about human made climate change now, most of them do so only superficially and very optimistically.
