Melissa Fleming is spot on when she calls for hope based communication:

As for the doomism, I’m convinced us communicators need a shift of tone. Few people now deny the planet is warming (though shocking numbers apparently still reject the link to human activity). The time for focusing solely on the problems is over. Now is the time to galvanize audiences for change.

The only way to do this is by offering hope. Storytelling focused on solutions, that highlights and celebrates people and places doing the right thing can empower audiences to look beyond messages of impending doom and see we have the tools and knowledge to secure a livable future.
