That's an important question. My thought is that it doesn't really matter in the short term. Our ecosystems out here in the west won't withstand another couple of decades of this. Any attempts to fix the root cause haven't worked fast enough, so it's time to try something else. In the long term, I hope that the economic forces of cheap renewables and energy storage might be enough to get us down to a reasonable PPM. And maybe, just maybe, we'll see advances in sequestration that get us down to where we were before. I'm not an expert, so please don't take any of my views as fact. I'm just a layman trying to find some hope in what looks like a pretty hopeless situation.
