When there's broad acceptance by the public that there really is a problem and that the cost of doing nothing is huge, viable solutions will come.
Except the
slight little problem that nobody actually knows the cost of doing nothing.
In summary, we have this:
1) man is polluting the environment on a vast scale. It is likely this is impacting the environment, and is likely to continue doing so.
2) Reducing pollution, including greenhouse gasses and such, would be good, but nobody has a real workable framework yet to achieve such a thing. All we have is vague notions and efforts to increase taxation and the scope of government.
3) Governments in places like China, India, Russia etc are not going to be on board with whatever framework is set up if it negatively impacts their economy, so a large percentage of pollution will remain unaffected no matter what we do.
4) We don't know the actual impact or costs of doing nothing. We have models that have been proven over and over again to be woefully inadequate, and some vague predictions.
5) we don't know the cost / impact of some of the proposed "solutions", either from an economic perspective or from an environmental / climate perspective. We don't know what they will really cost, and we don't know if they'll do any good (or even do harm).
6) This whole issue has effectively been driven out of the realm of science into the realm of politics, making it even more unlikely that we're going to get real (scientific) answers to a lot of the questions.
Given this scenario, it makes absolutely no sense to take any large scale steps until a lot more information is available.
