OK, Slintper, my comment above referred to your repeated admonitions ("how many times do I have to tell you") about why I fail to communicate ("your weakness") that in your estimation uses words you struggle with. Sorry about that. My vocab is pretty normal, and I certainly don't intend to take most of my interlocutors for fools. Not a single other person has ever complained. You are one of a kind.
To answer your questions:
1. "Socialism and state controls": Almost (but not all) those agitating for or driving the AGW agenda through society also happen to be statist-collectivists, ie people who want more state control over the lives or ordinary people, especially in economic and commercial affairs. They support laws that mitigate private property and transfer that expropriated control to the state. Socialism.
2. Regarding environmental blighting through pollution: Current legislation is more than up to the task. We don't need more.
3. I don't quite buy your rather jaundiced view of business. It's far too sweeping, almost to the point of being false. It is certainly a false generalisation. I know many big and small businesses and big and small business owners who care strongly about very much more than the bottom line. They don't need legislation and state controls to teach them about fair employment practices, generous employee benefits, generous social spending, respect for the environment, and so on. In fact, quite contrary to your reductionist caricature, most businesses see these things as entirely consistent with their responsibility for the bottom line, especially over the longer term. And so do many perhaps even most of their shareholders.
4. "Cramp and limit the lives of billions": The regime of heavy taxes, controls, and subsidies beloved of climate saviours will limit the economic development necessary for human development. The bottom three billion will never get the chance to develop and benefit from modern, industrial societies. Stunted development is the intention and legacy of the AGWers, because their solar-powered carbon-reduced future is always that: in the future. It can only happen when vast resources are deflected from the infrastructural investments that made the West wealthy are poured into significantly more expensive"green" technologies. And I say that as someone who's house is solar-powered.
