Numbers can be powerful things, but they don't necessarily help the average person grasp what's actually going on in science. Instead, personal stories tend to make a bigger impact. And that's understandable. Things you can see—or things that someone can show you—are going to stick in your head a bit more than a barrage of data.
This is especially a problem, I think, with climate change. Some of the largest impact of climate change, so far, have happened in places far removed from the experiences of the people who create the most anthropogenic greenhouse gases. So it's often hard to take the idea "the Earth is getting warmer" and really grok what that actually means.
That's why people like Will Steger are important. Steger is an explorer and science communicator who has won the National Geographic Society's John Oliver La Gorce Medal—an award that's also been given to Amelia Earhart, Robert Peary, Roald Amundsen and Jacques Cousteau.
He does most of his work in the Arctic and Antarctic, places where he has clearly seen the results of climate change. In a video of a presentation at the University of Minnesota, Steger shows you his experiences—and what they mean. How has climate change altered the landscape of the poles? What does that mean for the future of the Earth? Steger does a good job of making the data feel like something real.
I wish I could figure out how to embed this, but you should go watch it, nonetheless. It's a long video, but worth the time.
