We agree more than we think we do, but tech platforms distort our perceptions by amplifying the loudest, angriest and most dismissive voices online. In reality, they’re just a noisy faction. This Earth Day we ask Anthony Leiserowitz, Director of the Yale Program on Climate Change Communication, how he shifts public opinion on climate change. We’ll see how tech platforms could amplify voices of solidarity within our own communities. More importantly, we’ll see how they could empower 2 billion people to act in the face of global threats.
