Why optimism is a radical act

Optimism is not a mood. It’s a courageous choice — and some weeks, it’s harder than ever to make. Right now, as the devastation in Jamaica reminds us yet again of how climate change magnifies injustice and loss, it can feel almost impossible to hold on to hope. Yet that’s when it matters most. If we don't have hope, there is no reason to act: yet we know the science is clear that our actions matter. In this week’s Talking Climate newsletter, I’m honored to feature kindred spirit Anne Theres...

Jane Goodall's final lesson

This month, we lost one of the world’s greatest advocates for people and nature. When I was a child, she was the first scientist I ever saw on screen — a young woman in Africa, working with chimpanzees. Decades later, I met her backstage at the Paris climate talks: still tireless, still hopeful, still reminding us that “only when our clever brain and our human heart work together in harmony can we achieve our true potential.” Even in her final days, Dr. Jane Goodall was urging us not ...
