"Lack of political will" ignores the complexity of the situation, when actors are motivated to cheat or exclude themselves from consensus. It's not a far cry from saying we lack the political will to end all wars.
I'm an engineer. Rather than complaining about what I wish I could do if I only had the resources, I think about what I can do with the resources that I have. In the case of something like fossil fuel, I think about how to create a less expensive alternative. Truly cheap wind/solar would put oil out of business by default.
This is also why I idolize Elon Musk. Rather than complaining about the lack of political will on the part of governments to get humanity off Earth permanently and stop using fossil fuel altogether, he created SpaceX and Tesla, and is making it profitable to solve humanity's deepest problems.
