And if the the question was how can we reduce greenhouse gas emissions you'd have clear cut solution.
I mean, short-term effective start (or ramp up, where it's already started) steadily shifting the massive subsidies we're feeding into fossil fuels into... not fossil fuels. Even beyond various sorts of regulation or direct investment opportunities in renewables or emission capture/reduction, you do that and suddenly the market becomes even more interested than it already was in building infrastructure et al that puts less emissions in the air.
And that's just one pretty bloody straightforward solution to greenhouse gas emissions, maybe not a silver bullet or "best" solution, but an effective one that isn't some kind of convoluted 20 year plan or whatever.
It's not exhaustive, folks more plugged in to the renewable et al field have been beating their various drums on stuff like that probably longer than either of us have been alive. There's a pile of pretty bloody clear cut ways to help on that front if certain folks with more money than sense would stop getting in the friggin' way.
Bloody clear cut is not the scientific method. Unlike the previous proposition, the debate on climate change is inherently political involving economic, social, and political ramifications. For example in the UK, many would find your bloody straightforward solution vastly insufficient arguing that UK should do much more than steady shift, although interestingly even if tomorrow UK drop from the face of earth it this will not significantly effect climate change.
Addressing climate change requires international cooperation (particularly that of China) meaning that you have to worry about international actors which have conflicting perspectives, sense of urgency, capabilities, and focus on their own interests.
I already touched on this in another thread, but that was about narratives and Russia:
[..]More importantly, one should understand that climate change is global problem, but green tech is not a viable or desirable solution for everyone, and thus someone will need to pick up the slack. Then there are super national considerations, and political realities.
For example, in Russia solar and wind energy are not as viable as they are in north Africa and north-west Europe respectively. Russia lack the infrastructure, even countries like Germany had issues, and Russia due to dilapidated state and its huge size would need to invest MUCH more with far LESS profit margins (wrose if you consider electric car charging stations). There are security considerations, many advanced schemes require cooperation and dependence on other countries, and one may not want the possibility of your industry grinding into halt with a flick of switch or hitting couple of main transmission lines. Finally, there are economic realities (Russia have a lot of cheap fissile fuels) and the global market.
Here just few other quick points of the many issues involved here:
* The argument is that shift to a low-carbon economy can provide new economic opportunities, it would also impact existing industries and those who depend on them (cost of living too?) and historically these things tend to effect disproportionately particularly low-income communities with job retraining may not be accessible everywhere
* The high cost of infrastructure can be a barrier to developing and even developed countries, an opportunity cost loss that would have negative effects on their economic growth.
* Tough its called green tech it would require significant resources, the extraction and manufacturing of which would inevitably cause much environmental degradation and human rights abuses in the usual suspects with weak environmental and labor protections.
* Power politics, I am sure that if the west give it Taiwan China would be amicable to a big compromise.. ( Not sure that anything short of a blowjob from Biden could do the same for Putin )
Anyway. Your expletives hide that your greater good equitable solution is faith based. You nor anyone else can formulate a clear solution for climate change that would address all the above. This is why international effort have been lackluster with everyone agreeing on a small step in the right direction that everyone can live with.
