In short, no, because your question is heavily loaded and based on false assumptions and assertions.

Firstly governments can only more or less wield the degree of power citizens will collectively accede. Even in a seemingly autocratic China, if the CCP goes too far it would risk being removed, and knows it. The CCP operates under something comparable to The Heavens Mandate of the past. It is largely because the CCP has delivered exceptional improvements to most Chinese peoples economic conditions and expectations, that they remain in power. Another example is the Covid mandates which governments were eventually forced to give up on when too many citizens objected/refused to comply. Very few democratic governments that imposed Covid mandates remained in power at the next election. So consider this when you talk hypothetically about governments being given absolute power- we are all ultimately the government and governments can only wield, more or less, the power we accede to them.

Given the above reality about the nature of government power (rather than your hypothetical but unobtainable absolute) it is in fact very difficult for governments to deal with climate change.

The 'best effort' so far, collectively, the Paris Agreement has been agreed to by all governments except

Iran Libya Yemen And now the USA

Notwithstanding that the Paris Agreement doesn't appear very effective- I am no expert on it but the impression is it is so mired in compromise that its not going to have much effect...because to have effect sacrifices need to be made and politicians have struggled to pledge sacrifices on behalf of their citizens to whom they have to answer. The need to act decisively and collectively in the global best interest is challenging when such significant sacrifices would need to be made to succeed.

So theoretically, solving climate crisis, imo, relies upon enough citizens globally acknowledging there is a problem and supporting government action to resolve it. It is not a problem that will be solved as long as there is significant citizen level resistance to the science behind it and the need for it- this is why bullshit such as is being propagated here on SN by the OP and others deserves to be challenged.

The combination of small but vocal deniers and the very wealthy vested interests who inherently do not want to reduce emissions, is enough to endanger everyone.
