"the only known option for countering it requires government (or world) regulation."

Disagree. The regulation is only neccesary, if the common people/companys don't acknowledge the problem.

And even then, I don't think regulation helps much. More likely the opposite. Because if it is just ordered from above, then many just get childish rebellish and do the opposite. This is in my opinion the main problem.

Conservative people also like unpolluted citys I believe (side effect of electric cars) - most of them just taken a anti position to the leftish-green-hippi-liberal pro-enviroment stand.

So if people wants it, then it will happen. But I believe, we are allready on a good way. It just takes time to change the core of our industry and transport ... it is a huge effort. And will it be too late? That depends. I don't think it will be the end of the world, if the polar bear goes distinct or the netherlands get flooded. And we are allready causing great distruction to nature and people are starving by the millions. And this might get worse, but it is all connected, as the global population numbers are still greatly increasing who all want more things. So I don't see how regulating things down in Europe or US can help with that on a global scale.

So we as humanity have big problems, yes, but climate change is only one of them. And the solution to most, in my opinion, is better technology which will supply humanity in a sustainable way. Once people are not hungry anymore and are educated and connected with the rest of the world, then they usually tend to think, before just making more babys - about wheter they really want to raise a child and into what world they want to raise that child ...

And back to the topic, if you don't tell the conservatives what to do and think, but just show them how it can be done differently, then they will change, too, I believe.
