Dear Mr. President

Remember when adults were, like, really smart? Here’s one, talking about climate change: “I believe there is weather, I believe there is change and I believe it goes up and it goes down and it goes up again and it changes depending on the years and centuries.” But wiser voices are weighing in. “Burning all these fossil fuels creates carbon dioxide into our atmosphere and gets stuck,” That’s Diego, 12, reading from his letter, one of thousands collected by Protect Our Winters as part of its effort to mobilize the outdoor sports community against climate change. Who’s the grown-up now?
