An Inconvenient Truth, a documentary that exposes and predicts climate change, also features Gore's personal activities in the film. Published in a global tour of the briefing, Gore pointed to the scientific evidence for global warming, discussed the economic and political dimensions of global warming, and stated his belief that if human-generated greenhouse gases are not reduced, the global climate will change significantly in the near future. .
The film contains many passages to counter those who believe that global warming is not apparent or proven. Gore, for example, discusses the risk of melting ice sheets in Greenland or Antarctica, which could raise global sea levels by nearly 6 meters, flood coastal areas, and make about 100 million refugees as a result. Greenland's melting ice and snow have lower salinity levels, which could disrupt the Gulf Stream and cause temperatures to plummet in northern Europe.
