Powerful stories of frontline communities' climate solutions can change the world
When you're trying to persuade people to do something important, you can present statistics, policy statements, graphs, and spreadsheets. But without a story that paints a picture of what's at stake, touches the heartstrings, and sparks the imagination to envision possibilities, it's hard to move people to take action. One formula for accelerating transformational change is to amplify the right message from the right messenger at the right moment in time.
