Maybe I'm not getting your point, but Assad regime is secular dictatorship, more or less? So if you wanted to say that this is something completely impossible, well, the metaphor is not quite correct. And Iran before 1979 revolution could be considered secular dictatorship as well.
A green dictatorship would signal that everyone is given equal treatment. It's also an emergency measure.
Of course the word "dictatorship" has a very bad connotation here, because it implies oppression and violation of human rights, but that's not what I am advocating.
I am advocating for the revocation of the right to emit co2. It is a very strong restriction when look around you, because consumers are really friendly towards their lifestyle which directly finance lobbying efforts to avoid a carbon tax.
What is needed to do, while the industry adapt, is to allow the minimum, necessary items people needs to live: food, water, hygiene, shelter etc. while diminishing co2 emissions to their most lowest possible, and let industry to work without emissions to gradually change their process.
You cannot trust the industry to reduce emissions and do a slow switch because it's going to be too slow, and you cannot trust liberalism to find quick solutions if there is no strong enough incentives. Lobbies are never going to let change happen. It's going to be too slow and chaotic, not to mention fraud and people who will disagree with human responsibility.
Look at Tocqueville. Democracy is great, but when there is urgency about a complicated problem, democracy can be a problem.
If a political party or politician proposed what you're saying, they probably wouldn't get elected. If they tried it when in power, then the next party who gets elected would probably withdraw said restrictions. If they tried to 'turn off democracy' to do this, then people would get extremely angry, probably revolt and there would be a huge debacle. Especially given that worldwide, it'd be seen as an authoritarian coup in a democratic society, and responded to with economic sanctums, anger on the international stage and perhaps a war/support for overthrowing the government.
The problem isn't that such a dictatorship or authoritarian rule is necessarily against the long term interests of the population (though many authoritarian regimes (including China) would argue the same thing for their countries). It's that it's not democratic, not backed by most of the population and (perhaps rightly) seen as an alarming development in a country's history.
> seen as an alarming development in a country's history.
What do you mean? How would "an alarming development" be problematic? Democracy or not, action is required, and despite knowledge of the problem, I don't see any progress. I have nothing against democracy.

I think there is enough support for drastic measures, I don't think instability is a big risk. And if there is not enough support today, there will be more at each new heatwave and forest fire.
