Climate change has become part of our daily lexicon. Rarely does a week pass when a hurricane, drought, wildfire, or some other climate disruption is not front page news. These headlines often offer dire predictions of mass migration as well—a bracing vision of hordes of people moving to greener pastures, often found further inland and further north, where some political leaders leverage the narrative to push their own agendas.

There’s a scene near the climax of Agatha Christie’s Murder on the Orient Express when Hercule Poirot starts to plot out the possible murderers. There’s Colonel Arbuthnot, who had opportunity and motive. There’s Mr. McQueen, suspicious in his transparent attempts to misdirect the detective. There’s even the haughty, toad-faced Princess Dragomiroff. Like practically everyone on the train, she had good reason to wish the evil Ratchett dead.

“We need to give more weight to the voices of people who are most affected by climate change,” says Vanessa Nakate, a prominent Ugandan climate activist, in this week’s Friday Podcast. At the local, regional, and global levels, Nakate’s work sheds light on the imperative for policymakers to value the lived experiences of oft-overlooked groups such as women, youths, and citizens of developing nations. “When I talk about climate justice, it is not something that I want for the future—it is something that I want right now, because our present is catastrophic,” she says.

It helps to think of collaboration as a skill to develop, rather than a value to impart, said Francesca Gino, Professor and Unit Head of Negotiation, Organization and Markets at Harvard Business School, at a recent Wilson Center virtual event on the importance of cross-sectoral collaboration. Many organizations make collaboration one of their values, she said. However, this has no substantial effect. “It could be a first step, but on its own it doesn’t create a culture where all of a sudden people are collaborating effectively,” Gino said.
