honest question: can you point me to any US politician that has stood up to a corporation or corporate interest with laws that effectively say, "No, you can't have what you want, the people need <this> instead." and - most importantly - got those laws passed? I can't think of one. I think obamacare came close (which became one of the most hardfought wins ever), and yet the health insurance lobby still came out ahead. I dare say that no congress shall ever pass a law that harms a corporation (a de facto constitutional amendment).
What does that have to do with carbon control ? ICE auto industry, coal industry, oil and gas, etc, would all be "harmed" if US lawmakers passed anything that had a material impact on CO2 emissions. It would require multiple layers of alternative realities for that to ever happen, in my (admittedly cynical) opinion. I'm sorry if this sounds like I'm saying we should give up/not try. I _want_ us to solve global warming. I just can't picture it happening (at least for the redress method I listed above).
