Under socialism, the workers’ state can impose mandatory emissions controls and implement emissions reduction technology in a coordinated fashion. The worst case scenario of global warming can be averted.
Such mandatory controls would need to be worldwide, not just nationwide. The question, as always, is how could such a global government be implemented – especially since we don’t have decades for this to happen. Action is needed now.
We need some kind of worldwide controlling body that has the power to mandate climate control changes because it’s highly doubtful that private enterprise will do it en masse on their own because of the cost. Such a controlling body would also have to be composed of highly competent (and non-corruptible) people. It would have to be able to build consensus and implement the changes in a way that made the players want to participate. Again, we don’t have time for conflict and violent disagreements, as the climate change clock continues to tick.
Also, solutions won’t scale worldwide. What works in the US won’t work in, say, Bangladesh. There are probably hundreds of millions of people who burn animal dung and chop down trees for fuel. While this is ecologically disastrous when done on a large scale, a governing body can’t tell them to stop doing so without providing alternative, clean fuel – not unless they want protests and uprisings. Here in the States, forcing coal plants to close would be politically impossible unless new sources of energy have already been created.
Somehow, we need worldwide consensus on climate change, then mandating the changes becomes relatively much simpler.
