Within my opinion it doesn't matter what we do as co2 is going to keep going up. Why do I think this? We have hit a natural tipping point in our rain forest and ocean sinks as our world has now reached a level of warmth enough to allow for release of co2 into our atmosphere. I was reading a report a few days ago about how the amazon release 20% of human emissions over its norm in the last few years because of heat and drought...The three biggest droughts in recorded history have all happened within the past 17 years there. It is becoming normal as their climate is changing. Other reports show that our ocean can't hold as much co2 and yet others show our corral reefs bleaching nearly every year within the last decade be it nino or not.
Sure, It matters in the way that following 8.5 or even 4.5 of the IPCC report would have likely made large portions of our planet uninhabitable for human life(yes, if we followed that I believe co2 levels would of reached a few thousand ppm's within the next couple of centuries and ended up ending very badly for us), BUT that isn't the point of this thread. What doesn't matter is the reality that we have either reached the tipping points for some major sinks or are about to in others to cause centuries worth of added co2 release into our atmosphere from natural sources. We're locked in for at least 500ppm by mid century and that hasn't occurred in 6-8 million years at the minimum. That my friend is enough to kill off the current rain forest and it will take centuries for new rainforest to develop in order to take over!
Our human emissions will go down as china and india are doing as we speak but it is too late not to get seriously hurt from climate change. So yes, we have saved our species from extinction with the actions of China and India but things will still get ugly.
