Al Gore’s climate documentary “An Inconvenient Truth” arrived in theaters 20 years ago, in May 2006. The film had a profound effect on the public’s awareness and understanding of climate change, a number of surveys found.

I count myself among those who were dramatically influenced by “An Inconvenient Truth.”

In 2006, the topic of climate change had not yet significantly breached the public consciousness. Despite having just embarked on a career as an environmental scientist and having recently completed my graduate studies with degrees in astrophysics and physics, I had only a vague notion about the problem of climate change before seeing the documentary.
