The rate of co2 growth is no longer exponential. This is improvement. Yes, it's still growing, but at a slower rate than it used to. We're moving in the right direction, thought much too slowly.

Think of it like a big ship hurtling along.

Currently, we're braking. Still moving forward but slower. We need to stop and reverse, and that's the plan, but we need to do it faster.

All of this has made a difference. Between 2000 and 2010, global emissions rose 3 percent per year on average. But between 2011 and 2019, emissions grew more slowly, at roughly 1 percent per year.
