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.
Which is unfortunate because even if we dropped emissions to zero tomorrow, we would still be in for a few more decades of escalating climate crisis.
In the grand spectrum of what's already be chosen as far as climate change goes, this is just the very, very beginning. Our chance to act to prevent what we're seeing now was 30-40 years ago.
