PHILADELPHIA — It was a jarring transition. At the Democratic National Convention last Wednesday, a video by James Cameron depicted the impacts of climate change against a dramatic score — global warming as disaster movie, essentially. Then California Gov. Jerry Brown took the stage and said climate change “affects the entire earth and all living things. It’s slow. It’s relentless.” But even as they tried to emphasize the importance of climate change, speakers struggled to make it resonate.

The evening became much more powerful when it turned to an emotional string of speeches about gun violence. Christine Leinonen, the mother of an Orlando nightclub shooting victim, spoke, as did Erica Smegielski, the daughter of a Sandy Hook victim, and two survivors of the Charleston church shooting, Felicia Sanders and Polly Sheppard. Sen. Chris Murphy of Connecticut, who’s advocated for gun control legislation since the Sandy Hook shooting, also gave a passionate speech, as well as former congresswoman Gabrielle Giffords, who is still recovering from a 2011 shooting. Each had a story to tell of how gun violence has hurt them and loved ones. And it wasn’t the only night Democrats zeroed in on gun control, highlighting personal stories to show why many Americans have had enough of lax policies.

I couldn’t help but wonder: Where are the personal, powerful stories about climate change?
