CO2 will rise, but it will eventually necessary uncouple from it's relationship to temperature at which point some other factor we are wholy unaware of will probably do something as equally disturbing to our environmental "equilibrium".
If you transform the system in respect to time, you'll find that from some perspective almost nothing ever happened, and from another the whole thing was wildly unstable and unpredictable.
It already doesn't matter what CO2 levels are doing now. Up and to the right and how hard is probably completely irrelevant. What matters is the flux of the system, and everything points to the fact that weve already left the station. There's no unwinding this thing, and it's not going where anyone thinks it's going.
The truly conservative thing to be doing would be to prepare ourselves for the most violent future, but instead what we're trying to do is grip onto the past with our already dying hand. Weakening our heart at the very moment we need to bolster it.
Everything is going to be fine, but you and I will be dead. I assure you of that.
