Robert Gifford, a psychologist at the University of Victoria in British Columbia who studies the behavioral barriers to combating climate change, calls these habits of mind “dragons of inaction.” We have trouble imagining a future drastically different from the present. We block out complex problems that lack simple solutions. We dislike delayed benefits and so are reluctant to sacrifice today for future gains. And we find it harder to confront problems that creep up on us than emergencies that hit quickly. “You almost couldn’t design a problem that is a worse fit with our underlying psychology,” says Anthony Leiserowitz, director of the Yale Project on Climate Change Communication.
