Climate change affects everyone, but it is especially noticeable for children. How should we discuss this sometimes scary topic with them? Anna Murray asks an expert. My children ask me many questions. Where do babies come from? How do fish breathe underwater? Why is the sky blue? Why do I have to brush my teeth if I'm going to fall out anyway? I usually know what to say, even if it sometimes means a quick google on my phone. But my nine-year-old stopped me at dinner a few weeks ago with this casual question: “What is climate change? I decided to be as scientific as possible with my answer and mumbled something about the warming of the planet. I didn't talk about what a warming planet means for all of us. Mostly because I'm a coward who can't face talk of an existential crisis over spaghetti bologna, but also because I want my kids to have as much time as possible before any anxious thoughts about the future creep in. But I guess I can't stick my head in the sand forever, so I talked to someone who knows more about children and climate change than I do. (Anna Murray, Opinions and Explainers Editor)
