As the decade draws to a close, we will celebrate that our efforts have cut emissions in half globally over the past 10 years. Many countries will reach the goal of zero carbon emissions far sooner than their leaders thought possible. We will finally be on pace for a world without catastrophic climate change. But that will be only a small part of our achievement.

We will have remade what it looks and feels like to be alive. We will have done all this because we had to in order to survive. But, after it is done, we will realise that we did it so that we could thrive.

We will be unable to remember what the old world was like. The key, in hindsight, was understanding that revolutionary change starts with changing how we see how each of us fit into the world.
