WHEN I THINK of the incredible challenges we must confront in the face of a changing climate, my mind focuses on young people. Eventually, they will be the ones either to enjoy the fruits or bear the burdens resulting from actions taken today.
I think of my 9-year-old granddaughter. By the time she turns 20, she may be witness to climate change so profound that it pushes an additional 100 million people into poverty. By the time she turns 40, 140 million may become climate migrants— people forced to flee homes that are no longer safe or able to provide them with livelihoods. And if she lives to be 90, the planet may be 3–4° hotter and barely livable.
Unless we act. We can avoid this bleak future, and we know what we have to do—reduce emissions, offset what cannot be reduced, and adapt to new climate realities. No individual or institution can stand on the sidelines.
