Your framing of the argument seems a bit off to me. If global warming, therefore Marxism and since Marxism is a bad idea, therefore we should ignore any potential global warming. The concentration of CO2 and its environmental impacts are independent of any policy solution, it's just a physics problem. I think we should start there. I also think dismissing a few degrees change as no big deal is probably unwise in a system as complex as global climate.
I am with you with a 'and therefore, tax oil companies and immediately switch to unreliable solutions' is peak idiocy and will do more to make the problem worse than better, but a sober look at a nuclear future and a grid with a renewable mix is not liberal alarmism and lunacy.
It's been cooler with more CO2 and hotter with less. CO2 is not now, nor was ever, a pollutant or cause for changes. If there was a "Big Water" to go after, instead of "Big Oil", they'd be focused on water vapor which is loads more impactful than CO2.
In all the ruckus about AGW, they stopped looking at actual causes like solar cycles and the like.
