10 years on – did this film achieve what it set out to do – raise public awareness and change people’s behaviour in order to reduce greenhouse gas emissions? While the direct effect of the original screening of the film may have dissipated, the impact of those inspired to communicate realities of climate change persists. For me, the film precipitated a series of events that ultimately redirected the course of my life. An Inconvenient Truth wasn’t just behaviour-changing, it was life-changing. No lab experiment can quantify that level of impact.
