Eleven years after "An Inconvenient Truth" helped bring the issues of global warming-and man's role in it's creation and possible curbing-prominently into the national discourse, former vice president Al Gore returns with another probing consideration of the consequences of unchecked fossil fuel consumption. The progress regarding movement towards renewable energy on various fronts across the planet, and the acknowledgment of the political hurdles that yet remain, are strikingly outlined in this effort. 98 min. Widescreen; Soundtrack: English.
