Two decades have passed since Al Gore’s movie An Inconvenient Truth hit theaters, in May 2006, catapulting climate change into the global spotlight. The film, with its dramatic visuals and dire warnings, transformed the issue from a niche ecological concern into a front-page crisis. World leaders in rich countries began labeling it an “existential threat,” and it dominated international agendas. Gore’s message especially resonated with the elites who travel by private jet to attend global conferences, and it inspired a generation of influencers, activists, and policymakers.
As we approach the film’s 20th anniversary, it’s a time to reflect on not just its impact but its accuracy. The film’s predictions of escalating catastrophes have largely failed to materialize, its policy prescriptions have fallen short, and the $16 trillion currently spent in pursuit of its vision has delivered scant benefits. An Inconvenient Truth encapsulates the past two decades of climate debate: heavy on emotion and costs, light on evidence and benefits.
