It appears that the film begins with a report on the dire situation regarding climate changes on our planet but ends with hope that the rapidly-expanding renewable energy industry may yet save the day.

Not everyone may know that when Al Gore studied at University of California at San Diego, one of his teachers was Roger Revelle, the first scientist to use the term 'greenhouse effect'. Al Gore has stated that since he had access to the political realm thru his father, a U.S. Congressman and Senator from Tennessee, he decided to enter politics himself in order to battle climate change.
