When former US vice president Al Gore's An Inconvenient Truth came out in 2006, it landed with a bang. The documentary on the dangerous reality of global warming appeared to actually gain some traction with centrists—and maybe conservatives, too. But fast-forward a decade, and it seems that progress on the public perception of climate change has gone in reverse. This fallen world is the new setting for Gore's follow-up, An Inconvenient Sequel: Truth to Power. A white-haired, slightly more spacious Gore travels from the melting Greenland ice sheets to a flooded Miami Beach to demonstrate the impacts of climate change. He still gives a damned fine PowerPoint presentation, and he's as single-mindedly passionate about the issue as ever. But in many ways, Gore makes the same pitch he made in 2006. And that's where An Inconvenient Sequel fails: It doesn't address the root of the problem. by Sydney Brownstone
